MassBank of America (MoNA), is an auto curating repository for storing, comparing and querying mass spectra of chemical compounds. It is metadata centric and it was designed to allow easy integration into other tools by utilize its REST based application programming interface. At the current time it contains over 200k predicted and 40k unique experimental mass spectra and their associated metadata. The predicted spectra were obtained by utilizing the lipid blast library and the experimental spectra were acquired from 30 different facilities all over the world, including several major research facilities in the United States and Japan. MoNA is utilizing the InChI Key as unique identifier for chemicals and is designed for easy scalability and expendability. This is realized by utilizing common applications like nginx, grails, AngularJS, postgresSQL and tomcat. MoNA is currently integrated in applications like MSDial, BinBase, MZMine and the statistics package R. This was accomplished by utilizing its REST based API, which is also utilized by its main AngularJS based web interface. We consider MoNA to be highly useful for crosslinking mass spectra in publications, identification of unknowns and integration in data acquisition software. This package provides you with access to the REST api of the main MoNA installation.

Pact provider ============= sub project of https://github.com/DiUS/pact-jvm The pact provider is responsible for verifying that an API provider adheres to a number of pacts authored by its clients This library provides the basic tools required to automate the process, and should be usable on its own in many instances. Framework and build tool specific bindings will be provided in separate libraries that build on top of this core functionality. ### Provider State Before each interaction is executed, the provider under test will have the opportunity to enter a state. Generally the state maps to a set of fixture data for mocking out services that the provider is a consumer of (they will have their own pacts) The pact framework will instruct the test server to enter that state by sending: POST &quot;${config.stateChangeUrl.url}/setup&quot; { &quot;state&quot; : &quot;${interaction.stateName}&quot; } ### An example of running provider verification with junit This example uses Groovy, JUnit 4 and Hamcrest matchers to run the provider verification. As the provider service is a DropWizard application, it uses the DropwizardAppRule to startup the service before running any test. **Warning:** It only grabs the first interaction from the pact file with the consumer, where there could be many. (This could possibly be solved with a parameterized test) ```groovy class ReadmeExamplePactJVMProviderJUnitTest { @ClassRule public static TestRule startServiceRule = new DropwizardAppRule&lt;DropwizardConfiguration&gt;( TestDropwizardApplication.class, ResourceHelpers.resourceFilePath(&quot;dropwizard/test-config.yaml&quot;)) private static ProviderInfo serviceProvider private static Pact&lt;RequestResponseInteraction&gt; testConsumerPact private static ConsumerInfo consumer @BeforeClass static void setupProvider() { serviceProvider = new ProviderInfo(&quot;Dropwizard App&quot;) serviceProvider.setProtocol(&quot;http&quot;) serviceProvider.setHost(&quot;localhost&quot;) serviceProvider.setPort(8080) serviceProvider.setPath(&quot;/&quot;) consumer = new ConsumerInfo() consumer.setName(&quot;test_consumer&quot;) consumer.setPactSource(new UrlSource( ReadmeExamplePactJVMProviderJUnitTest.getResource(&quot;/pacts/zoo_app-animal_service.json&quot;).toString())) testConsumerPact = PactReader.loadPact(consumer.getPactSource()) as Pact&lt;RequestResponseInteraction&gt; } @Test void runConsumerPacts() { // grab the first interaction from the pact with consumer Interaction interaction = testConsumerPact.interactions.get(0) // setup the verifier ProviderVerifier verifier = setupVerifier(interaction, serviceProvider, consumer) // setup any provider state // setup the client and interaction to fire against the provider ProviderClient client = new ProviderClient(serviceProvider, new HttpClientFactory()) Map&lt;String, Object&gt; failures = new HashMap&lt;&gt;() verifier.verifyResponseFromProvider(serviceProvider, interaction, interaction.getDescription(), failures, client) if (!failures.isEmpty()) { verifier.displayFailures(failures) } // Assert all good assertThat(failures, is(empty())) } private ProviderVerifier setupVerifier(Interaction interaction, ProviderInfo provider, ConsumerInfo consumer) { ProviderVerifier verifier = new ProviderVerifier() verifier.initialiseReporters(provider) verifier.reportVerificationForConsumer(consumer, provider) if (!interaction.getProviderStates().isEmpty()) { for (ProviderState providerState: interaction.getProviderStates()) { verifier.reportStateForInteraction(providerState.getName(), provider, consumer, true) } } verifier.reportInteractionDescription(interaction) return verifier } } ``` ### An example of running provider verification with spock This example uses groovy and spock to run the provider verification. Again the provider service is a DropWizard application, and is using the DropwizardAppRule to startup the service. This example runs all interactions using spocks Unroll feature ```groovy class ReadmeExamplePactJVMProviderSpockSpec extends Specification { @ClassRule @Shared TestRule startServiceRule = new DropwizardAppRule&lt;DropwizardConfiguration&gt;(TestDropwizardApplication, ResourceHelpers.resourceFilePath(&apos;dropwizard/test-config.yaml&apos;)) @Shared ProviderInfo serviceProvider ProviderVerifier verifier def setupSpec() { serviceProvider = new ProviderInfo(&apos;Dropwizard App&apos;) serviceProvider.protocol = &apos;http&apos; serviceProvider.host = &apos;localhost&apos; serviceProvider.port = 8080 serviceProvider.path = &apos;/&apos; serviceProvider.hasPactWith(&apos;zoo_app&apos;) { pactSource = new FileSource(new File(ResourceHelpers.resourceFilePath(&apos;pacts/zoo_app-animal_service.json&apos;))) } } def setup() { verifier = new ProviderVerifier() } def cleanup() { // cleanup provider state // ie. db.truncateAllTables() } def cleanupSpec() { // cleanup provider } @Unroll def &quot;Provider Pact - With Consumer #consumer&quot;() { expect: verifyConsumerPact(consumer).empty where: consumer &lt;&lt; serviceProvider.consumers } private Map verifyConsumerPact(ConsumerInfo consumer) { Map failures = [:] verifier.initialiseReporters(serviceProvider) verifier.runVerificationForConsumer(failures, serviceProvider, consumer) if (!failures.empty) { verifier.displayFailures(failures) } failures } } ```

pact-jvm-consumer-junit5 ======================== JUnit 5 support for Pact consumer tests ## Dependency The library is available on maven central using: * group-id = `au.com.dius` * artifact-id = `pact-jvm-consumer-junit5_2.12` * version-id = `3.6.x` ## Usage ### 1. Add the Pact consumer test extension to the test class. To write Pact consumer tests with JUnit 5, you need to add `@ExtendWith(PactConsumerTestExt)` to your test class. This replaces the `PactRunner` used for JUnit 4 tests. The rest of the test follows a similar pattern as for JUnit 4 tests. ```java @ExtendWith(PactConsumerTestExt.class) class ExampleJavaConsumerPactTest { ``` ### 2. create a method annotated with `@Pact` that returns the interactions for the test For each test (as with JUnit 4), you need to define a method annotated with the `@Pact` annotation that returns the interactions for the test. ```java @Pact(provider=&quot;ArticlesProvider&quot;, consumer=&quot;test_consumer&quot;) public RequestResponsePact createPact(PactDslWithProvider builder) { return builder .given(&quot;test state&quot;) .uponReceiving(&quot;ExampleJavaConsumerPactTest test interaction&quot;) .path(&quot;/articles.json&quot;) .method(&quot;GET&quot;) .willRespondWith() .status(200) .body(&quot;{\&quot;responsetest\&quot;: true}&quot;) .toPact(); } ``` ### 3. Link the mock server with the interactions for the test with `@PactTestFor` Then the final step is to use the `@PactTestFor` annotation to tell the Pact extension how to setup the Pact test. You can either put this annotation on the test class, or on the test method. For examples see [ArticlesTest](src/test/java/au/com/dius/pact/consumer/junit5/ArticlesTest.java) and [MultiTest](src/test/groovy/au/com/dius/pact/consumer/junit5/MultiTest.groovy). The `@PactTestFor` annotation allows you to control the mock server in the same way as the JUnit 4 `PactProviderRule`. It allows you to set the hostname to bind to (default is `localhost`) and the port (default is to use a random port). You can also set the Pact specification version to use (default is V3). ```java @ExtendWith(PactConsumerTestExt.class) @PactTestFor(providerName = &quot;ArticlesProvider&quot;) public class ExampleJavaConsumerPactTest { ``` **NOTE on the hostname**: The mock server runs in the same JVM as the test, so the only valid values for hostname are: | hostname | result | | -------- | ------ | | `localhost` | binds to the address that localhost points to (normally the loopback adapter) | | `127.0.0.1` or `::1` | binds to the loopback adapter | | host name | binds to the default interface that the host machines DNS name resolves to | | `0.0.0.0` or `::` | binds to the all interfaces on the host machine | #### Matching the interactions by provider name If you set the `providerName` on the `@PactTestFor` annotation, then the first method with a `@Pact` annotation with the same provider name will be used. See [ArticlesTest](src/test/java/au/com/dius/pact/consumer/junit5/ArticlesTest.java) for an example. #### Matching the interactions by method name If you set the `pactMethod` on the `@PactTestFor` annotation, then the method with the provided name will be used (it still needs a `@Pact` annotation). See [MultiTest](src/test/groovy/au/com/dius/pact/consumer/junit5/MultiTest.groovy) for an example. ### Injecting the mock server into the test You can get the mock server injected into the test method by adding a `MockServer` parameter to the test method. ```java @Test void test(MockServer mockServer) throws IOException { HttpResponse httpResponse = Request.Get(mockServer.getUrl() + &quot;/articles.json&quot;).execute().returnResponse(); assertThat(httpResponse.getStatusLine().getStatusCode(), is(equalTo(200))); } ``` This helps with getting the base URL of the mock server, especially when a random port is used. ## Changing the directory pact files are written to By default, pact files are written to `target/pacts` (or `build/pacts` if you use Gradle), but this can be overwritten with the `pact.rootDir` system property. This property needs to be set on the test JVM as most build tools will fork a new JVM to run the tests. For Gradle, add this to your build.gradle: ```groovy test { systemProperties[&apos;pact.rootDir&apos;] = &quot;$buildDir/custom-pacts-directory&quot; } ``` For maven, use the systemPropertyVariables configuration: ```xml &lt;project&gt; [...] &lt;build&gt; &lt;plugins&gt; &lt;plugin&gt; &lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt; &lt;artifactId&gt;maven-surefire-plugin&lt;/artifactId&gt; &lt;version&gt;2.18&lt;/version&gt; &lt;configuration&gt; &lt;systemPropertyVariables&gt; &lt;pact.rootDir&gt;some/other/directory&lt;/pact.rootDir&gt; &lt;buildDirectory&gt;${project.build.directory}&lt;/buildDirectory&gt; [...] &lt;/systemPropertyVariables&gt; &lt;/configuration&gt; &lt;/plugin&gt; &lt;/plugins&gt; &lt;/build&gt; [...] &lt;/project&gt; ``` For SBT: ```scala fork in Test := true, javaOptions in Test := Seq(&quot;-Dpact.rootDir=some/other/directory&quot;) ``` ### Using `@PactFolder` annotation [3.6.2+] You can override the directory the pacts are written in a test by adding the `@PactFolder` annotation to the test class. ## Forcing pact files to be overwritten (3.6.5+) By default, when the pact file is written, it will be merged with any existing pact file. To force the file to be overwritten, set the Java system property `pact.writer.overwrite` to `true`. ## Unsupported The current implementation does not support tests with multiple providers. This will be added in a later release. # Having values injected from provider state callbacks (3.6.11+) You can have values from the provider state callbacks be injected into most places (paths, query parameters, headers, bodies, etc.). This works by using the V3 spec generators with provider state callbacks that return values. One example of where this would be useful is API calls that require an ID which would be auto-generated by the database on the provider side, so there is no way to know what the ID would be beforehand. The following DSL methods all you to set an expression that will be parsed with the values returned from the provider states: For JSON bodies, use `valueFromProviderState`.&lt;br/&gt; For headers, use `headerFromProviderState`.&lt;br/&gt; For query parameters, use `queryParameterFromProviderState`.&lt;br/&gt; For paths, use `pathFromProviderState`. For example, assume that an API call is made to get the details of a user by ID. A provider state can be defined that specifies that the user must be exist, but the ID will be created when the user is created. So we can then define an expression for the path where the ID will be replaced with the value returned from the provider state callback. ```java .pathFromProviderState(&quot;/api/users/${id}&quot;, &quot;/api/users/100&quot;) ``` You can also just use the key instead of an expression: ```java .valueFromProviderState(&apos;userId&apos;, &apos;userId&apos;, 100) // will look value using userId as the key ```

One example of where this would be useful is API calls that require an ID which would be auto-generated by the database on the provider side, so there is no way to know what the ID would be beforehand. The following DSL methods all you to set an expression that will be parsed with the values returned from the provider states: For JSON bodies, use `valueFromProviderState`.&lt;br/&gt; For headers, use `headerFromProviderState`.&lt;br/&gt; For query parameters, use `queryParameterFromProviderState`.&lt;br/&gt; For paths, use `pathFromProviderState`. For example, assume that an API call is made to get the details of a user by ID. A provider state can be defined that specifies that the user must be exist, but the ID will be created when the user is created. So we can then define an expression for the path where the ID will be replaced with the value returned from the provider state callback. ```java .pathFromProviderState(&quot;/api/users/${id}&quot;, &quot;/api/users/100&quot;) ``` You can also just use the key instead of an expression: ```java .valueFromProviderState(&apos;userId&apos;, &apos;userId&apos;, 100) // will look value using userId as the key ```
