 * 
Using info and markup

 *
 * 

 * One of the parameters to Suite's run method is a Reporter, which
 * will collect and report information about the running suite of tests.
 * Information about suites and tests that were run, whether tests succeeded or failed, 
 * and tests that were ignored will be passed to the Reporter as the suite runs.
 * Most often the reporting done by default will be sufficient, but
 * occasionally you may wish to provide custom information to the Reporter from a test.
 * For this purpose, an Informer that will forward information
 * to the current Reporter is provided via the info parameterless method.
 * You can pass the extra information to the Informer via its apply method.
 * The Informer will then pass the information to the Reporter via an InfoProvided event.
 * Here's an example that shows both a direct use as well as an indirect use through the methods
 * of GivenWhenThen:
 * 

 *
 * 
 * package org.scalatest.examples.suite.info
 *
 * import collection.mutable
 * import org.scalatest._
 * 
 * class SetSuite extends Suite with GivenWhenThen {
 *
 *   def `test: an element can be added to an empty mutable Set` {
 *
 *     given("an empty mutable Set")
 *     val set = mutable.Set.empty[String]
 *
 *     when("an element is added")
 *     set += "clarity"
 *
 *     then("the Set should have size 1")
 *     assert(set.size === 1)
 *
 *     and("the Set should contain the added element")
 *     assert(set.contains("clarity"))
 *
 *     info("That's all folks!")
 *   }
 * }
 * 

 *
 * If you run this Suite from the interpreter, you will see the messages
 * included in the output:
 *
 * 
 * scala> new SetSuite execute
 * SetSuite:
 * - an element can be added to an empty mutable Set
 *   + Given an empty mutable Set
 *   + When an element is added
 *   + Then the Set should have size 1
 *   + And the Set should contain the added element
 *   + That's all folks!
 * 

 *
 * 

 * Trait Suite also carries a Documenter named markup, which
 * you can use to transmit markup text to the Reporter.
 * 

 * --------------
 * 
Assertions and ===

 *
 * 

 * Inside test methods in a Suite, you can write assertions by invoking assert and passing in a Boolean expression,
 * such as:
 * 

 *
 * 
 * val left = 2
 * val right = 1
 * assert(left == right)
 * 

 *
 * 

 * If the passed expression is true, assert will return normally. If false,
 * assert will complete abruptly with a TestFailedException. This exception is usually not caught
 * by the test method, which means the test method itself will complete abruptly by throwing the TestFailedException. Any
 * test method that completes abruptly with an exception is considered a failed
 * test. A test method that returns normally is considered a successful test.
 * 

 *
 * 

 * If you pass a Boolean expression to assert, a failed assertion will be reported, but without
 * reporting the left and right values. You can alternatively encode these values in a String passed as
 * a second argument to assert, as in:
 * 

 * 
 * 
 * val left = 2
 * val right = 1
 * assert(left == right, left + " did not equal " + right)
 * 

 *
 * 

 * Using this form of assert, the failure report will include the left and right values, 
 * helping you debug the problem. However, ScalaTest provides the === operator to make this easier.
 * (The === operator is defined in trait Assertions which trait Suite extends.)
 * You use it like this:
 * 

 *
 * 
 * val left = 2
 * val right = 1
 * assert(left === right)
 * 

 *
 * 

 * Because you use === here instead of ==, the failure report will include the left
 * and right values. For example, the detail message in the thrown TestFailedException from the assert
 * shown previously will include, "2 did not equal 1".
 * From this message you will know that the operand on the left had the value 2, and the operand on the right had the value 1.
 * 

 *
 * 

 * If you're familiar with JUnit, you would use ===
 * in a ScalaTest Suite where you'd use assertEquals in a JUnit TestCase.
 * The === operator is made possible by an implicit conversion from Any
 * to Equalizer. If you're curious to understand the mechanics, see the documentation for
 * Equalizer and the convertToEqualizer method.
 * 

 *
 * 
Expected results

 *
 * Although === provides a natural, readable extension to Scala's assert mechanism,
 * as the operands become lengthy, the code becomes less readable. In addition, the === comparison
 * doesn't distinguish between actual and expected values. The operands are just called left and right,
 * because if one were named expected and the other actual, it would be difficult for people to
 * remember which was which. To help with these limitations of assertions, Suite includes a method called expectResult that
 * can be used as an alternative to assert with ===. To use expectResult, you place
 * the expected value in parentheses after expectResult, followed by curly braces containing code 
 * that should result in the expected value. For example:
 *
 * 
 * val a = 5
 * val b = 2
 * expectResult(2) {
 *   a - b
 * }
 * 

 *
 * 

 * In this case, the expected value is 2, and the code being tested is a - b. This expectation will fail, and
 * the detail message in the TestFailedException will read, "Expected 2, but got 3."
 * 

 *
 * 
Intercepted exceptions

 *
 * 

 * Sometimes you need to test whether a method throws an expected exception under certain circumstances, such
 * as when invalid arguments are passed to the method. You can do this in the JUnit style, like this:
 * 

 *
 * 
 * val s = "hi"
 * try {
 *   s.charAt(-1)
 *   fail()
 * }
 * catch {
 *   case _: IndexOutOfBoundsException => // Expected, so continue
 * }
 * 

 *
 * 

 * If charAt throws IndexOutOfBoundsException as expected, control will transfer
 * to the catch case, which does nothing. If, however, charAt fails to throw an exception,
 * the next statement, fail(), will be executed. The fail method always completes abruptly with
 * a TestFailedException, thereby signaling a failed test.
 * 

 *
 * 

 * To make this common use case easier to express and read, ScalaTest provides an intercept
 * method. You use it like this:
 * 

 *
 * 
 * val s = "hi"
 * intercept[IndexOutOfBoundsException] {
 *   s.charAt(-1)
 * }
 * 

 *
 * 

 * This code behaves much like the previous example. If charAt throws an instance of IndexOutOfBoundsException,
 * intercept will return that exception. But if charAt completes normally, or throws a different
 * exception, intercept will complete abruptly with a TestFailedException. The intercept method returns the
 * caught exception so that you can inspect it further if you wish, for example, to ensure that data contained inside
 * the exception has the expected values. Here's an example:
 * 

 *
 * 
 * val s = "hi"
 * val caught =
 *   intercept[IndexOutOfBoundsException] {
 *     s.charAt(-1)
 *   }
 * assert(caught.getMessage === "String index out of range: -1")
 * 

 *
 * 
Using matchers and other assertions

 *
 * 

 * ScalaTest also supports another style of assertions via its matchers DSL. By mixing in
 * trait ShouldMatchers, you can 
 * write suites that look like:
 * 

 *
 * 
 * package org.scalatest.examples.suite.matchers
 *
 * import org.scalatest._
 *
 * class SetSuite extends Suite with ShouldMatchers {
 *
 *   def `test: an empty Set should have size 0` {
 *     Set.empty.size should equal (0)
 *   }
 *
 *   def `test: invoking head on an empty Set should produce NoSuchElementException` {
 *     evaluating { Set.empty.head } should produce [NoSuchElementException]
 *   }
 * }
 * 

 * 
 * 
If you prefer the word "must" to the word "should," you can alternatively mix in
 * trait MustMatchers.
 * 

 *
 * 

 * If you are comfortable with assertion mechanisms from other test frameworks, chances
 * are you can use them with ScalaTest. Any assertion mechanism that indicates a failure with an exception
 * can be used as is with ScalaTest. For example, to use the assertEquals
 * methods provided by JUnit or TestNG, simply import them and use them. (You will of course need
 * to include the relevant JAR file for the framework whose assertions you want to use on either the
 * classpath or runpath when you run your tests.) 
 * 

 */

/**
 * A suite of tests. A Suite instance encapsulates a conceptual
 * suite (i.e., a collection) of tests.
 *
 * 

 * This trait provides an interface composed of "lifecycle methods" that allow suites of tests to be run.
 * Its implementation enables a default way of writing and executing tests.  Subtraits and subclasses can
 * override Suite's lifecycle methods to enable other ways of writing and executing tests.
 * 

 *
 * 

 * Prior to ScalaTest 2.0.M4, trait Suite served two purposes: 1) It served as the base
 * class of ScalaTest's family of style traits, and 2) It was itself a style trait in which tests are methods.
 * Although it will continue to serve its first purpose, it has been deprecated as a style trait. Pre-existing code
 * that used Suite as a style trait to define tests as methods will continue to work during the
 * deprecation period, but will generate a deprecation warning. Please change all such uses of Suite
 * to use trait Spec instead.
 * 

 *
 * 
Nested suites

 *
 * 

 * A Suite can refer to a collection of other Suites,
 * which are called nested Suites. Those nested  Suites can in turn have
 * their own nested  Suites, and so on. Large test suites can be organized, therefore, as a tree of
 * nested Suites.
 * This trait's run method, in addition to invoking its
 * test methods, invokes run on each of its nested Suites.
 * 

 *
 * 

 * A List of a Suite's nested Suites can be obtained by invoking its
 * nestedSuites method. If you wish to create a Suite that serves as a
 * container for nested Suites, whether or not it has test methods of its own, simply override nestedSuites
 * to return a List of the nested Suites. Because this is a common use case, ScalaTest provides
 * a convenience Suites class, which takes a variable number of nested Suites as constructor
 * parameters. Here's an example:
 * 

 *
 * 
 * package org.scalatest.examples.suite.nested
 *
 * import org.scalatest._
 *
 * class ASuite extends FunSuite {
 *   test("A should have ASCII value 41 hex") {
 *     assert('A' === 0x41)
 *   }
 *   test("a should have ASCII value 61 hex") {
 *     assert('a' === 0x61)
 *   }
 * }
 * class BSuite extends FunSuite {
 *   test("B should have ASCII value 42 hex") {
 *     assert('B' === 0x42)
 *   }
 *   test("b should have ASCII value 62 hex") {
 *     assert('b' === 0x62)
 *   }
 * }
 * class CSuite extends FunSuite {
 *   test("C should have ASCII value 43 hex") {
 *     assert('C' === 0x43)
 *   }
 *   test("c should have ASCII value 63 hex") {
 *     assert('c' === 0x63)
 *   }
 * }
 *
 * class ASCIISuite extends Suites(
 *   new ASuite,
 *   new BSuite,
 *   new CSuite
 * )
 * 

 *
 * 

 * If you now run ASCIISuite:
 * 

 *
 * 
 * scala> new ASCIISuite execute
 * 

 *
 * 

 * You will see reports printed to the standard output that indicate the nested
 * suites—ASuite, BSuite, and
 * CSuite—were run:
 * 

 *
 * 
 * ASCIISuite:
 * ASuite:
 * - A should have ASCII value 41 hex
 * - a should have ASCII value 61 hex
 * BSuite:
 * - B should have ASCII value 42 hex
 * - b should have ASCII value 62 hex
 * CSuite:
 * - C should have ASCII value 43 hex
 * - c should have ASCII value 63 hex
 * 

 *
 * 

 * Note that Runner can discover Suites automatically, so you need not
 * necessarily define nested Suites explicitly. See the documentation
 * for Runner for more information.
 * 

 *
 * 
The config map

 *
 * 

 * In some cases you may need to pass information to a suite of tests.
 * For example, perhaps a suite of tests needs to grab information from a file, and you want
 * to be able to specify a different filename during different runs.  You can accomplish this in ScalaTest by passing
 * the filename in a config map of key-value pairs, which is passed to run as a Map[String, Any].
 * The values in the config map are called "config objects," because they can be used to configure
 * suites, reporters, and tests.
 * 

 *
 * 

 * You can specify a string config object is via the ScalaTest Runner, either via the command line
 * or ScalaTest's ant task.
 * (See the documentation for Runner for information on how to specify 
 * config objects on the command line.)
 * The config map is passed to run, runNestedSuites, runTests, and runTest,
 * so one way to access it in your suite is to override one of those methods. If you need to use the config map inside your tests, you
 * can access it from the NoArgTest passed to withFixture, or the OneArgTest passed to
 * withFixture in the traits in the org.scalatest.fixture package. (See the
 * documentation for fixture.Suite
 * for instructions on how to access the config map in tests.)
 * 

 *
 * 
Executing suites in parallel

 *
 * 

 * The run method takes as one of its parameters an optional Distributor. If 
 * a Distributor is passed in, this trait's implementation of run puts its nested
 * Suites into the distributor rather than executing them directly. The caller of run
 * is responsible for ensuring that some entity runs the Suites placed into the 
 * distributor. The -P command line parameter to Runner, for example, will cause
 * Suites put into the Distributor to be run in parallel via a pool of threads.
 * If you wish to execute the tests themselves in parallel, mix in ParallelTestExecution.
 * 

 *
 * 
 * 
Treatment of java.lang.Errors

 *
 * 

 * The Javadoc documentation for java.lang.Error states:
 * 

 *
 * 

 * An Error is a subclass of Throwable that indicates serious problems that a reasonable application should not try to catch. Most
 * such errors are abnormal conditions.
 * 

 *
 * 

 * Because Errors are used to denote serious errors, trait Suite and its subtypes in the ScalaTest API do not always treat a test
 * that completes abruptly with an Error as a test failure, but sometimes as an indication that serious problems
 * have arisen that should cause the run to abort. For example, if a test completes abruptly with an OutOfMemoryError, 
 * it will not be reported as a test failure, but will instead cause the run to abort. Because not everyone uses Errors only to represent serious
 * problems, however, ScalaTest only behaves this way for the following exception types (and their subclasses):
 * 

 *
 * 
    
 * 
  • java.lang.annotation.AnnotationFormatError
    • 
 * 
  • java.awt.AWTError
    • 
 * 
  • java.nio.charset.CoderMalfunctionError
    • 
 * 
  • javax.xml.parsers.FactoryConfigurationError
    • 
 * 
  • java.lang.LinkageError
    • 
 * 
  • java.lang.ThreadDeath
    • 
 * 
  • javax.xml.transform.TransformerFactoryConfigurationError
    • 
 * 
  • java.lang.VirtualMachineError
    • 
 * 

 *
 * 

 * The previous list includes all Errors that exist as part of Java 1.5 API, excluding java.lang.AssertionError. ScalaTest
 * does treat a thrown AssertionError as an indication of a test failure. In addition, any other Error that is not an instance of a
 * type mentioned in the previous list will be caught by the Suite traits in the ScalaTest API and reported as the cause of a test failure. 
 * 

 *
 * 

 * Although trait Suite and all its subtypes in the ScalaTest API consistently behave this way with regard to Errors,
 * this behavior is not required by the contract of Suite. Subclasses and subtraits that you define, for example, may treat all
 * Errors as test failures, or indicate errors in some other way that has nothing to do with exceptions.
 * 

 *
 * 
Extensibility

 *
 * 

 * Trait Suite provides default implementations of its methods that should
 * be sufficient for most applications, but many methods can be overridden when desired. Here's
 * a summary of the methods that are intended to be overridden:
 * 

 *
 * 
    
 * 
  • run - override this method to define custom ways to run suites of
 *   tests.
    • 
 * 
  • runNestedSuites - override this method to define custom ways to run nested suites.
    • 
 * 
  • runTests - override this method to define custom ways to run a suite's tests.
    • 
 * 
  • runTest - override this method to define custom ways to run a single named test.
    • 
 * 
  • testNames - override this method to specify the Suite's test names in a custom way.
    • 
 * 
  • tags - override this method to specify the Suite's test tags in a custom way.
    • 
 * 
  • nestedSuites - override this method to specify the Suite's nested Suites in a custom way.
    • 
 * 
  • suiteName - override this method to specify the Suite's name in a custom way.
    • 
 * 
  • expectedTestCount - override this method to count this Suite's expected tests in a custom way.
    • 
 * 

 *
 * 

 * For example, this trait's implementation of testNames performs reflection to discover methods starting with test,
 * and places these in a Set whose iterator returns the names in alphabetical order. If you wish to run tests in a different
 * order in a particular Suite, perhaps because a test named testAlpha can only succeed after a test named
 * testBeta has run, you can override testNames so that it returns a Set whose iterator returns
 * testBeta before testAlpha. (This trait's implementation of run will invoke tests
 * in the order they come out of the testNames Set iterator.)
 * 

 *
 * 

 * Alternatively, you may not like starting your test methods with test, and prefer using @Test annotations in
 * the style of Java's JUnit 4 or TestNG. If so, you can override testNames to discover tests using either of these two APIs
 * @Test annotations, or one of your own invention. (This is in fact
 * how org.scalatest.junit.JUnitSuite and org.scalatest.testng.TestNGSuite work.)
 * 

 *
 * 

 * Moreover, test in ScalaTest does not necessarily mean test method. A test can be anything that can be given a name,
 * that starts and either succeeds or fails, and can be ignored. In org.scalatest.FunSuite, for example, tests are represented
 * as function values. This
 * approach might look foreign to JUnit users, but may feel more natural to programmers with a functional programming background.
 * To facilitate this style of writing tests, FunSuite overrides testNames, runTest, and run such that you can 
 * define tests as function values.
 * 

 *
 * 

 * You can also model existing JUnit 3, JUnit 4, or TestNG tests as suites of tests, thereby incorporating tests written in Java into a ScalaTest suite.
 * The "wrapper" classes in packages org.scalatest.junit and org.scalatest.testng exist to make this easy.
 * No matter what legacy tests you may have, it is likely you can create or use an existing Suite subclass that allows you to model those tests
 * as ScalaTest suites and tests and incorporate them into a ScalaTest suite. You can then write new tests in Scala and continue supporting
 * older tests in Java.

  /**
   * Executes one or more tests in this Suite, printing results to the standard output.
   *
   * 

   * This method invokes run on itself, passing in values that can be configured via the parameters to this
   * method, all of which have default values. This behavior is convenient when working with ScalaTest in the Scala interpreter.
   * Here's a summary of this method's parameters and how you can use them:
   * 

   *
   * 

   * The testName parameter
   * 

   *
   * 

   * If you leave testName at its default value (of null), this method will pass None to
   * the testName parameter of run, and as a result all the tests in this suite will be executed. If you
   * specify a testName, this method will pass Some(testName) to run, and only that test
   * will be run. Thus to run all tests in a suite from the Scala interpreter, you can write:
   * 

   *
   * 
   * scala> new ExampleSuite execute
   * 

   *
   * 

   * (The above syntax actually invokes the overloaded parameterless form of execute, which calls this form with its default parameter values.)
   * To run just the test named "my favorite test" in a suite from the Scala interpreter, you would write:
   * 

   *
   * 
   * scala> new ExampleSuite execute ("my favorite test")
   * 

   *
   * 

   * Or:
   * 

   *
   * 
   * scala> new ExampleSuite execute (testName = "my favorite test")
   * 

   *
   * 

   * The configMap parameter
   * 

   *
   * 

   * If you provide a value for the configMap parameter, this method will pass it to run. If not, the default value
   * of an empty Map will be passed. For more information on how to use a config map to configure your test suites, see
   * the config map section in the main documentation for this trait. Here's an example in which you configure
   * a run with the name of an input file:
   * 

   *
   * 
   * scala> new ExampleSuite execute (configMap = Map("inputFileName" -> "in.txt")
   * 

   *
   * 

   * The color parameter
   * 

   *
   * 

   * If you leave the color parameter unspecified, this method will configure the reporter it passes to run to print
   * to the standard output in color (via ansi escape characters). If you don't want color output, specify false for color, like this:
   * 

   *
   * 
   * scala> new ExampleSuite execute (color = false)
   * 

   *
   * 

   * The durations parameter
   * 

   *
   * 

   * If you leave the durations parameter unspecified, this method will configure the reporter it passes to run to
   * not print durations for tests and suites to the standard output. If you want durations printed, specify true for durations,
   * like this:
   * 

   *
   * 
   * scala> new ExampleSuite execute (durations = true)
   * 

   *
   * 

   * The shortstacks and fullstacks parameters
   * 

   *
   * 

   * If you leave both the shortstacks and fullstacks parameters unspecified, this method will configure the reporter
   * it passes to run to not print stack traces for failed tests if it has a stack depth that identifies the offending
   * line of test code. If you prefer a short stack trace (10 to 15 stack frames) to be printed with any test failure, specify true for
   * shortstacks:
   * 

   *
   * 
   * scala> new ExampleSuite execute (shortstacks = true)
   * 

   *
   * 

   * For full stack traces, set fullstacks to true:
   * 

   *
   * 
   * scala> new ExampleSuite execute (fullstacks = true)
   * 

   *
   * 

   * If you specify true for both shortstacks and fullstacks, you'll get full stack traces.
   * 

   *
   * 

   * The stats parameter
   * 

   *
   * 

   * If you leave the stats parameter unspecified, this method will not fire RunStarting and either RunCompleted
   * or RunAborted events to the reporter it passes to run.
   * If you specify true for stats, this method will fire the run events to the reporter, and the reporter will print the
   * expected test count before the run, and various statistics after, including the number of suites completed and number of tests that
   * succeeded, failed, were ignored or marked pending. Here's how you get the stats:
   * 

   *
   * 
   * scala> new ExampleSuite execute (stats = true)
   * 

   *
   *
   * 

   * To summarize, this method will pass to run:
   * 

   * 
    
   * 
  • testName - None if this method's testName parameter is left at its default value of null, else Some(testName).
   * 
  • reporter - a reporter that prints to the standard output
    • 
   * 
  • stopper - a Stopper whose apply method always returns false
    •

   * 

   * Note:  In ScalaTest, the terms "execute" and "run" basically mean the same thing and
   * can be used interchangably. The reason this method isn't named run is that it takes advantage of
   * default arguments, and you can't mix overloaded methods and default arguments in Scala. (If named run,
   * this method would have the same name but different arguments than the main run method that
   * takes seven arguments. Thus it would overload and couldn't be used with default argument values.)
   * 

   *
   * 

   * Design note: This method has two "features" that may seem unidiomatic. First, the default value of testName is null.
   * Normally in Scala the type of testName would be Option[String] and the default value would
   * be None, as it is in this trait's run method. The null value is used here for two reasons. First, in
   * ScalaTest 1.5, execute was changed from four overloaded methods to one method with default values, taking advantage of
   * the default and named parameters feature introduced in Scala 2.8.
   * To not break existing source code, testName needed to have type String, as it did in two of the overloaded
   * execute methods prior to 1.5. The other reason is that execute has always been designed to be called primarily
   * from an interpeter environment, such as the Scala REPL (Read-Evaluate-Print-Loop). In an interpreter environment, minimizing keystrokes is king.
   * A String type with a null default value lets users type suite.execute("my test name") rather than
   * suite.execute(Some("my test name")), saving several keystrokes.
   * 

   *
   * 

   * The second non-idiomatic feature is that shortstacks and fullstacks are all lower case rather than
   * camel case. This is done to be consistent with the Shell, which also uses those forms. The reason 
   * lower case is used in the Shell is to save keystrokes in an interpreter environment.  Most Unix commands, for
   * example, are all lower case, making them easier and quicker to type.  In the ScalaTest
   * Shell, methods like shortstacks, fullstacks, and nostats, etc., are 
   * designed to be all lower case so they feel more like shell commands than methods.
   * 

   *
   * @param testName the name of one test to run.
   * @param configMap a Map of key-value pairs that can be used by the executing Suite of tests.

   * This method, which simply invokes the other overloaded form of execute with default parameter values,

   * interpreter with a minimum of finger typing:

   * scala> new SetSpec execute
   * An empty Set
   * - should have size 0
   * - should produce NoSuchElementException when head is invoked !!! IGNORED !!!
   * 

   *
   * 

   * If you do ever want to invoke execute outside the Scala interpreter, it is best style to invoke it with
   * empty parens to indicate it has a side effect, like this:
   * 

   *
   * 
   * // Use empty parens form in regular code (outside the Scala interpreter)
   * (new ExampleSuite).execute()
   * 

   */

   * A Map whose keys are String tag names with which tests in this Suite are marked, and
   * whose values are the Set of test names marked with each tag.  If this Suite contains no tags, this
   * method returns an empty Map.
   *
   * 

   * This trait's implementation of this method uses Java reflection to discover any Java annotations attached to its test methods. The
   * fully qualified name of each unique annotation that extends TagAnnotation is considered a tag. This trait's
   * implementation of this method, therefore, places one key/value pair into to the
   * Map for each unique tag annotation name discovered through reflection. The mapped value for each tag name key will contain
   * the test method name, as provided via the testNames method. 
   * 

   * 
   * 

   * In addition to test methods annotations, this trait's implementation will also auto-tag test methods with class level annotations.  
   * For example, if you annotate @Ignore at the class level, all test methods in the class will be auto-annotated with @Ignore.
   * 

   *
   * 

   * Subclasses may override this method to define and/or discover tags in a custom manner, but overriding method implementations
   * should never return an empty Set as a value. If a tag has no tests, its name should not appear as a key in the
   * returned Map.

  *
  * 

  * Suite has been deprecated as a style trait. During the deprecation period, the following behavior will continue
  * to work as before, but will go away at the conclusion of the deprecation period:
  * This trait's implementation of this method uses Java reflection to discover all public methods whose name starts with "test",
  * which take either nothing or a single Informer as parameters. For each discovered test method, it assigns a test name
  * comprised of just the method name if the method takes no parameters, or the method name plus (Informer) if the
  * method takes a Informer. Here are a few method signatures and the names that this trait's implementation assigns them:
  * 

  *
  * 
  * def testCat() {}         // test name: "testCat"
  * def testCat(Informer) {} // test name: "testCat(Informer)"
  * def testDog() {}         // test name: "testDog"
  * def testDog(Informer) {} // test name: "testDog(Informer)"
  * def test() {}            // test name: "test"
  * def test(Informer) {}    // test name: "test(Informer)"
  * 

  *
  * 

  * This trait's implementation of this method returns an immutable Set of all such names, excluding the name
  * testNames. The iterator obtained by invoking elements on this
  * returned Set will produce the test names in their natural order, as determined by String's
  * compareTo method.
  * 

  *
  * 

  * This trait's implementation of runTests invokes this method
  * and calls runTest for each test name in the order they appear in the returned Set's iterator.
  * Although this trait's implementation of this method returns a Set whose iterator produces String
  * test names in a well-defined order, the contract of this method does not required a defined order. Subclasses are free to
  * override this method and return test names in an undefined order, or in a defined order that's different from String's
  * natural order.
  * 

  *
  * 

  * Subclasses may override this method to produce test names in a custom manner. One potential reason to override testNames is
  * to run tests in a different order, for example, to ensure that tests that depend on other tests are run after those other tests.
  * Another potential reason to override is allow tests to be defined in a different manner, such as methods annotated @Test annotations
  * (as is done in JUnitSuite and TestNGSuite) or test functions registered during construction (as is
  * done in FunSuite and FunSpec).
  * 

  *
  * 

  * In ScalaTest's event model, a test may be surrounded by “scopes.” Each test and scope is associated with string of text.
  * A test's name is concatenation of the text of any surrounding scopes followed by the text provided with the test
  * itself, after each text element has been trimmed and one space inserted between each component. Here's an example:
  * 

  *
  * 
  * package org.scalatest.examples.freespec
  * 
  * import org.scalatest.FreeSpec
  * 
  * class SetSpec extends FreeSpec {
  * 
  *   "A Set" - {
  *     "when empty" - {
  *       "should have size 0" in {
  *         assert(Set.empty.size === 0)
  *       }
  *       
  *       "should produce NoSuchElementException when head is invoked" in {
  *         intercept[NoSuchElementException] {
  *           Set.empty.head
  *         }
  *       }
  *     }
  *   }
  * }
  * 

  *
  * 

  * The above FreeSpec contains two tests, both nested inside the same two scopes. The outermost scope names
  * the subject, A Set. The nested scope qualifies the subject with when empty. Inside that
  * scope are the two tests. The text of the tests are:
  * 

  *
  * 
    
  * 
  • should have size 0
    • 
  * 
  • should produce NoSuchElementException when head is invoked
    • 
  * 

  *
  * 

  * Therefore, the names of these two tests are:
  * 

  *
  * 
    
  * 
  • A Stack when empty should have size 0
    • 
  * 
  • A Stack when empty should produce NoSuchElementException when head is invoked
    • 
  * 

  *
  * 

  * Note that because the component scope and test text strings are trimmed, any leading or trailing space will be dropped
  * before they are strung together to form the test name, with each trimmed component separated by a space. If the scopes
  * in the above example had text " A Set " and " when empty ", and the first test had text
  * " should have size 0 ", its test name would still be the same, "A Set when empty should have size 0".
  *

   * This method takes a Filter, which encapsulates an optional Set of tag names that should be included
   * (tagsToInclude) and a Set that should be excluded (tagsToExclude), when deciding which
   * of this Suite's tests to run.
   * If tagsToInclude is None, all tests will be run
   * except those those belonging to tags listed in the tagsToExclude Set. If tagsToInclude is defined, only tests
   * belonging to tags mentioned in the tagsToInclude Set, and not mentioned in the tagsToExcludeSet
   * will be run. However, if testName is defined, tagsToInclude and tagsToExclude are essentially ignored.
   * Only if testName is None will tagsToInclude and tagsToExclude be consulted to
   * determine which of the tests named in the testNames Set should be run. This trait's implementation
   * behaves this way, and it is part of the general contract of this method, so all overridden forms of this method should behave
   * this way as well.  For more information on test tags, see the main documentation for this trait and for class Filter.
   * Note that this means that even if a test is marked as ignored, for example a test method in a Suite annotated with
   * org.scalatest.Ignore, if that test name is passed as testName to runTest, it will be invoked
   * despite the Ignore annotation.
   * 

   *
   * 

   * If testName is None, this trait's implementation of this method
   * invokes testNames on this Suite to get a Set of names of tests to potentially run.
   * (A testNames value of None essentially acts as a wildcard that means all tests in
   * this Suite that are selected by tagsToInclude and tagsToExclude should be run.)
   * For each test in the testName Set, in the order
   * they appear in the iterator obtained by invoking the elements method on the Set, this trait's implementation
   * of this method checks whether the test should be run based on the Filter.
   * If so, this implementation invokes runTest, passing in:
   * 

   *
   * 
    
   * 
  • testName - the String name of the test to run (which will be one of the names in the testNames Set)
    • 
   * 
  • reporter - the Reporter passed to this method, or one that wraps and delegates to it
    • 
   * 
  • stopper - the Stopper passed to this method, or one that wraps and delegates to it
    • 
   * 
  • configMap - the configMap passed to this method, or one that wraps and delegates to it
    • 
   * 

   *
   * 

   * If a test is marked with the org.scalatest.Ignore tag, implementations
   * of this method are responsible for ensuring a TestIgnored event is fired for that test
   * and that runTest is not called for that test.
   * 

   *
   * @param testName an optional name of one test to run. If None, all relevant tests should be run.
   *                 I.e., None acts like a wildcard that means run all relevant tests in this Suite.

If testName is None, this trait's implementation of this method

   *
   * 
    
   * 
  1. runNestedSuites(report, stopper, tagsToInclude, tagsToExclude, configMap, distributor)
    2. 
   * 
  2. runTests(testName, report, stopper, tagsToInclude, tagsToExclude, configMap)
    3. 
   * 

   *
   * 

   * If testName is defined, then this trait's implementation of this method
   * calls runTests, but does not call runNestedSuites. This behavior
   * is part of the contract of this method. Subclasses that override run must take
   * care not to call runNestedSuites if testName is defined. (The
   * OneInstancePerTest trait depends on this behavior, for example.)
   * 

   *
   * 

   * Subclasses and subtraits that override this run method can implement them without
   * invoking either the runTests or runNestedSuites methods, which
   * are invoked by this trait's implementation of this method. It is recommended, but not required,
   * that subclasses and subtraits that override run in a way that does not
   * invoke runNestedSuites also override runNestedSuites and make it
   * final. Similarly it is recommended, but not required,
   * that subclasses and subtraits that override run in a way that does not
   * invoke runTests also override runTests (and runTest,
   * which this trait's implementation of runTests calls) and make it
   * final. The implementation of these final methods can either invoke the superclass implementation
   * of the method, or throw an UnsupportedOperationException if appropriate. The
   * reason for this recommendation is that ScalaTest includes several traits that override
   * these methods to allow behavior to be mixed into a Suite. For example, trait
   * BeforeAndAfterEach overrides runTestss. In a Suite
   * subclass that no longer invokes runTests from run, the
   * BeforeAndAfterEach trait is not applicable. Mixing it in would have no effect.
   * By making runTests final in such a Suite subtrait, you make
   * the attempt to mix BeforeAndAfterEach into a subclass of your subtrait
   * a compiler error. (It would fail to compile with a complaint that BeforeAndAfterEach
   * is trying to override runTests, which is a final method in your trait.) 
   *

   * Throws TestPendingException to indicate a test is pending.

   * 

   * A pending test is one that has been given a name but is not yet implemented. The purpose of
   * pending tests is to facilitate a style of testing in which documentation of behavior is sketched
   * out before tests are written to verify that behavior (and often, the before the behavior of
   * the system being tested is itself implemented). Such sketches form a kind of specification of
   * what tests and functionality to implement later.
   * 

   *
   * 

   * To support this style of testing, a test can be given a name that specifies one
   * bit of behavior required by the system being tested. The test can also include some code that
   * sends more information about the behavior to the reporter when the tests run. At the end of the test,
   * it can call method pending, which will cause it to complete abruptly with TestPendingException.
   * Because tests in ScalaTest can be designated as pending with TestPendingException, both the test name and any information
   * sent to the reporter when running the test can appear in the report of a test run. (In other words,
   * the code of a pending test is executed just like any other test.) However, because the test completes abruptly
   * with TestPendingException, the test will be reported as pending, to indicate
   * the actual test, and possibly the functionality it is intended to test, has not yet been implemented.
   * 

   *
   * 

   * Note: This method always completes abruptly with a TestPendingException. Thus it always has a side
   * effect. Methods with side effects are usually invoked with parentheses, as in pending(). This
   * method is defined as a parameterless method, in flagrant contradiction to recommended Scala style, because it 
   * forms a kind of DSL for pending tests. It enables tests in suites such as FunSuite or FunSpec
   * to be denoted by placing "(pending)" after the test name, as in:
   * 

   *
   * 
   * test("that style rules are not laws") (pending)
   * 

   *
   * 

   * Readers of the code see "pending" in parentheses, which looks like a little note attached to the test name to indicate
   * it is pending. Whereas "(pending()) looks more like a method call, "(pending)" lets readers
   * stay at a higher level, forgetting how it is implemented and just focusing on the intent of the programmer who wrote the code.

   * automatically turn back into a failing test once the problem originally causing the test to fail has been fixed.
   * At that point, you need only remove the pendingUntilFixed call. In other words, a
   * pendingUntilFixed surrounding a block of code that isn't broken is treated as a test failure.
   * The motivation for this behavior is to encourage people to remove pendingUntilFixed calls when

   to make room for the icon in that case. An info inside such a test will have level 1. And agin, in that
   case no need to subtract 1. Such a test is "outermost test" and the info inside is "in outermost test" in:
