Method Summary

Modifier and TypeMethod and Description

Overrides org.junit.internal.builders.AllDefaultPossibilitiesBuilder.annotatedBuilder.

private IgnoringRunnerDecorator
decorateIgnoredTestClass(Runner runner)

Instead of checking for the Ignore annotation and returning an IgnoredClassRunner from IgnoredBuilder, we've let the super class determine the regular runner that would have been used if Ignore hadn't been present.

protected IgnoredBuilder

public Runner
runnerForClass(Class<?> testClass)

Overrides org.junit.internal.builders.AllDefaultPossibilitiesBuilder.runnerForClass.

Override to calculate the correct runner for a test class at runtime.

private IgnoringRunnerDecorator decorateIgnoredTestClass(Runner runner)

Instead of checking for the Ignore annotation and returning an IgnoredClassRunner from IgnoredBuilder, we've let the super class determine the regular runner that would have been used if Ignore hadn't been present. Now, we decorate the runner to override its runtime behavior (i.e. skip execution) but return its regular org.junit.runner.Description.
