JMockit is a Java toolkit for automated developer testing. It contains mocking/faking APIs and a code coverage tool, supporting both JUnit and TestNG. The mocking APIs allow all kinds of Java code, without testability restrictions, to be tested in isolation from selected dependencies.

 * Startup fake that modifies the JUnit 4.5+ test runner so that it calls back to JMockit immediately after every test executes.
 * When that happens, JMockit will assert any expectations recorded during the test in {@link Expectations} subclasses.
 * 

* This class is not supposed to be accessed from user code. JMockit will automatically load it at startup. */ public final class FakeFrameworkMethod extends MockUp { @Nonnull private final JUnit4TestRunnerDecorator decorator = new JUnit4TestRunnerDecorator(); @Nullable @Mock public Object invokeExplosively(@Nonnull Invocation invocation, Object target, Object... params) throws Throwable { return decorator.invokeExplosively((FakeInvocation) invocation, target, params); } @Mock public static void validatePublicVoidNoArg(@Nonnull Invocation invocation, boolean isStatic, List errors) { FrameworkMethod it = invocation.getInvokedInstance(); assert it != null; int previousErrorCount = errors.size(); if (!isStatic && eachParameterContainsAKnownAnnotation(it.getMethod().getParameterAnnotations())) { it.validatePublicVoid(false, errors); } else { ((FakeInvocation) invocation).prepareToProceedFromNonRecursiveMock(); it.validatePublicVoidNoArg(isStatic, errors); } int errorCount = errors.size(); for (int i = previousErrorCount; i < errorCount; i++) { Throwable errorAdded = errors.get(i); StackTrace.filterStackTrace(errorAdded); } } private static boolean eachParameterContainsAKnownAnnotation(@Nonnull Annotation[][] parametersAndTheirAnnotations) { if (parametersAndTheirAnnotations.length == 0) { return false; } for (Annotation[] parameterAnnotations : parametersAndTheirAnnotations) { if (!containsAKnownAnnotation(parameterAnnotations)) { return false; } } return true; } private static boolean containsAKnownAnnotation(@Nonnull Annotation[] parameterAnnotations) { if (parameterAnnotations.length == 0) { return false; } for (Annotation parameterAnnotation : parameterAnnotations) { Class annotationType = parameterAnnotation.annotationType(); String annotationTypeName = annotationType.getName(); if ( "mockit.Tested mockit.Mocked mockit.Injectable mockit.Capturing".contains(annotationTypeName) || annotationType.isAnnotationPresent(Tested.class) ) { return true; } } return false; } }
