/**
 * Marks ArchUnit tests to be executed by the test infrastructure. These tests can have the following form:
 * 
 *     
 *         A static field of type {@link ArchRule} -> this rule will automatically be checked against the imported classes
 *     
 *     
 *         A static method with one parameter {@link JavaClasses} -> this method will be called with the imported classes
 *     
 * 
 * 
Example:
 * 
 *{@literal @}ArchTest
 * public static final ArchRule someRule = classes()... ;
 *
 *{@literal @}ArchTest
 * public static void someMethod(JavaClasses classes) {
 *     // do something with classes
 * }
