public final class TestParameterInjector
extends org.junit.runners.BlockJUnit4ClassRunner
A JUnit4 test runner which knows how to instantiate and run test classes where each test case may be parameterized with its own unique set of test parameters.

  • Constructor Details

    • TestParameterInjector

      public TestParameterInjector​(Class<?> testClass) throws org.junit.runners.model.InitializationError
      Throws:
      org.junit.runners.model.InitializationError

  • Method Details

    • createTestMethodProcessorList

      protected com.google.testing.junit.testparameterinjector.TestMethodProcessorList createTestMethodProcessorList()
      Returns the TestMethodProcessorList to use. This is meant to be overridden by subclasses.

    • finalizeCreatedTestInstance

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

    • shouldSortTestMethodsDeterministically

      @Deprecated protected boolean shouldSortTestMethodsDeterministically()
      Deprecated.
      Override sortTestMethods(java.util.stream.Stream<org.junit.runners.model.FrameworkMethod>) with preferred sorting strategy.
      If true, all test methods (across different TestMethodProcessors) will be sorted in a deterministic way.

      Deterministic means that the order will not change, even when tests are added/removed or between releases.

    • sortTestMethods

      protected Stream<org.junit.runners.model.FrameworkMethod> sortTestMethods​(Stream<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.
