All Implemented Interfaces:

public class SpincastJUnitRunner
extends org.junit.runners.BlockJUnit4ClassRunner

A JUnit Runner that will create a single instance *per class*. By default, JUnit creates a new instance of the Test class for every @Test.

If the test class implements IBeforeAfterClassMethodsProvider, "beforeClass()" and "afterClass()" will be called on it.

You can also annotate the test class with ExpectingInstanciationException: then the instantiation of the class will be expected to fail. If such an exception is expected and does occure, the tests won't be run. Note that Junit requires at least one test method to be present, so if @ExpectingInstanciationException is used, we dynamically add the "hashcode()" method, always available on each object, as a dummy "test" method.

Constructor Detail

SpincastJUnitRunner

public SpincastJUnitRunner(Class<?> klass)
                    throws org.junit.runners.model.InitializationError

Throws:

org.junit.runners.model.InitializationError

Method Detail

isExpectingInstanciationException

public boolean isExpectingInstanciationException()

createTest

public Object createTest()
                  throws Exception

Overrides:

createTest in class org.junit.runners.BlockJUnit4ClassRunner

Throws:

Exception

computeTestMethods

protected List<org.junit.runners.model.FrameworkMethod> computeTestMethods()

If the class is annotated with @ExpectingInstanciationException no @Test method are required. But Junit wants at least one method, so we add the always present "hashCode" as a test method.

Overrides:

computeTestMethods in class org.junit.runners.BlockJUnit4ClassRunner

methodBlock

protected org.junit.runners.model.Statement methodBlock(org.junit.runners.model.FrameworkMethod method)

If an instanciation exception occured, we don't run the actual tests!

Overrides:

methodBlock in class org.junit.runners.BlockJUnit4ClassRunner

run

public void run(org.junit.runner.notification.RunNotifier notifier)

Overrides:

run in class org.junit.runners.ParentRunner<org.junit.runners.model.FrameworkMethod>
