Class TestContextManager

java.lang.Object

org.springframework.test.context.TestContextManager

public class TestContextManager
extends java.lang.Object

TestContextManager is the main entry point into the Spring TestContext Framework.

Specifically, a TestContextManager is responsible for managing a single TestContext and signaling events to all registered TestExecutionListeners at the following test execution points:

• before test class execution: prior to any before class methods of a particular testing framework (e.g., JUnit 4's @BeforeClass)
• test instance preparation: immediately following instantiation of the test instance
• before test method execution: prior to any before methods of a particular testing framework (e.g., JUnit 4's @Before)
• after test method execution: after any after methods of a particular testing framework (e.g., JUnit 4's @After)
• after test class execution: after any after class methods of a particular testing framework (e.g., JUnit 4's @AfterClass)

Support for loading and accessing application contexts, dependency injection of test instances, transactional execution of test methods, etc. is provided by ContextLoaders and TestExecutionListeners, which are configured via @ContextConfiguration and @TestExecutionListeners.

Bootstrapping of the TestContext, the default ContextLoader, default TestExecutionListeners, and their collaborators is performed by a TestContextBootstrapper, which is configured via @BootstrapWith.

Constructor Detail

TestContextManager

public TestContextManager(java.lang.Class<?> testClass)

Construct a new TestContextManager for the supplied test class.

Delegates to TestContextManager(TestContextBootstrapper) with the TestContextBootstrapper configured for the test class. If the @BootstrapWith annotation is present on the test class, either directly or as a meta-annotation, then its value will be used as the bootstrapper type; otherwise, the DefaultTestContextBootstrapper will be used.

Parameters:

testClass - the test class to be managed

See Also:

TestContextManager(TestContextBootstrapper)

TestContextManager

public TestContextManager(TestContextBootstrapper testContextBootstrapper)

Construct a new TestContextManager using the supplied TestContextBootstrapper and register the necessary TestExecutionListeners.

Delegates to the supplied TestContextBootstrapper for building the TestContext and retrieving the TestExecutionListeners.

Parameters:

testContextBootstrapper - the bootstrapper to use

See Also:

TestContextBootstrapper.buildTestContext(), TestContextBootstrapper.getTestExecutionListeners(), registerTestExecutionListeners(java.util.List<org.springframework.test.context.TestExecutionListener>)

Method Detail

getTestContext

public final TestContext getTestContext()

Get the TestContext managed by this TestContextManager.

registerTestExecutionListeners

public void registerTestExecutionListeners(java.util.List<TestExecutionListener> testExecutionListeners)

Register the supplied list of TestExecutionListeners by appending them to the list of listeners used by this TestContextManager.

See Also:

registerTestExecutionListeners(TestExecutionListener...)

registerTestExecutionListeners

public void registerTestExecutionListeners(TestExecutionListener... testExecutionListeners)

Register the supplied array of TestExecutionListeners by appending them to the list of listeners used by this TestContextManager.

getTestExecutionListeners

public final java.util.List<TestExecutionListener> getTestExecutionListeners()

Get the current TestExecutionListeners registered for this TestContextManager.

Allows for modifications, e.g. adding a listener to the beginning of the list. However, make sure to keep the list stable while actually executing tests.

getReversedTestExecutionListeners

private java.util.List<TestExecutionListener> getReversedTestExecutionListeners()

Get a copy of the TestExecutionListeners registered for this TestContextManager in reverse order.

beforeTestClass

public void beforeTestClass()
                     throws java.lang.Exception

Hook for pre-processing a test class before execution of any tests within the class. Should be called prior to any framework-specific before class methods (e.g., methods annotated with JUnit's @BeforeClass).

An attempt will be made to give each registered TestExecutionListener a chance to pre-process the test class execution. If a listener throws an exception, however, the remaining registered listeners will not be called.

Throws:

java.lang.Exception - if a registered TestExecutionListener throws an exception

See Also:

getTestExecutionListeners()

prepareTestInstance

public void prepareTestInstance(java.lang.Object testInstance)
                         throws java.lang.Exception

Hook for preparing a test instance prior to execution of any individual test methods, for example for injecting dependencies, etc. Should be called immediately after instantiation of the test instance.

The managed TestContext will be updated with the supplied testInstance.

An attempt will be made to give each registered TestExecutionListener a chance to prepare the test instance. If a listener throws an exception, however, the remaining registered listeners will not be called.

Parameters:

testInstance - the test instance to prepare (never null)

Throws:

java.lang.Exception - if a registered TestExecutionListener throws an exception

See Also:

getTestExecutionListeners()

beforeTestMethod

public void beforeTestMethod(java.lang.Object testInstance,
                             java.lang.reflect.Method testMethod)
                      throws java.lang.Exception

Hook for pre-processing a test before execution of the supplied test method, for example for setting up test fixtures, starting a transaction, etc. Should be called prior to any framework-specific before methods (e.g., methods annotated with JUnit's @Before).

The managed TestContext will be updated with the supplied testInstance and testMethod.

An attempt will be made to give each registered TestExecutionListener a chance to pre-process the test method execution. If a listener throws an exception, however, the remaining registered listeners will not be called.

Parameters:

testInstance - the current test instance (never null)

testMethod - the test method which is about to be executed on the test instance

Throws:

java.lang.Exception - if a registered TestExecutionListener throws an exception

See Also:

getTestExecutionListeners()

afterTestMethod

public void afterTestMethod(java.lang.Object testInstance,
                            java.lang.reflect.Method testMethod,
                            java.lang.Throwable exception)
                     throws java.lang.Exception

Hook for post-processing a test after execution of the supplied test method, for example for tearing down test fixtures, ending a transaction, etc. Should be called after any framework-specific after methods (e.g., methods annotated with JUnit's @After).

The managed TestContext will be updated with the supplied testInstance, testMethod, and exception.

Each registered TestExecutionListener will be given a chance to post-process the test method execution. If a listener throws an exception, the remaining registered listeners will still be called, but the first exception thrown will be tracked and rethrown after all listeners have executed. Note that registered listeners will be executed in the opposite order in which they were registered.

Parameters:

testInstance - the current test instance (never null)

testMethod - the test method which has just been executed on the test instance

exception - the exception that was thrown during execution of the test method or by a TestExecutionListener, or null if none was thrown

Throws:

java.lang.Exception - if a registered TestExecutionListener throws an exception

See Also:

getTestExecutionListeners()

afterTestClass

public void afterTestClass()
                    throws java.lang.Exception

Hook for post-processing a test class after execution of all tests within the class. Should be called after any framework-specific after class methods (e.g., methods annotated with JUnit's @AfterClass).

Each registered TestExecutionListener will be given a chance to post-process the test class. If a listener throws an exception, the remaining registered listeners will still be called, but the first exception thrown will be tracked and rethrown after all listeners have executed. Note that registered listeners will be executed in the opposite order in which they were registered.

Throws:

java.lang.Exception - if a registered TestExecutionListener throws an exception
