      • finalizeCreatedTestInstance

        protected void finalizeCreatedTestInstance​(Object testInstance)
        This method is run to perform optional additional operations on the test instance, right after it was created.

      • sortTestMethods

        protected com.google.common.collect.ImmutableList<org.junit.runners.model.FrameworkMethod> sortTestMethods​(com.google.common.collect.ImmutableList<org.junit.runners.model.FrameworkMethod> methods)
        Sort test methods (across different TestMethodProcessors).

        This should be deterministic. The order should not change, even when tests are added/removed or between releases.

      • getSupportedTestAnnotations

        protected com.google.common.collect.ImmutableList<Class<? extends Annotation>> getSupportedTestAnnotations()
        Returns classes used as annotations to indicate test methods.

        Defaults to Test.

      • getExtraTestRules

        protected List<org.junit.rules.TestRule> getExtraTestRules()
        TestRules that will be executed before the ones defined in the test class. This is meant to be overridden by subclasses.
