TestClassAware, Validatable, Node<JupiterEngineExecutionContext>, TestDescriptor

Direct Known Subclasses:

TestFactoryTestDescriptor, TestTemplateInvocationTestDescriptor

@API(status=INTERNAL,
     since="5.0")
public class TestMethodTestDescriptor
extends MethodBasedTestDescriptor

TestDescriptor for @Test methods.

Default Display Names

The default display name for a test method is the name of the method concatenated with a comma-separated list of parameter types in parentheses. The names of parameter types are retrieved using Class.getSimpleName(). For example, the default display name for the following test method is testUser(TestInfo, User).

   @Test
   void testUser(TestInfo testInfo, @Mock User user) { ... }
 

Since:

5.0

TestMethodTestDescriptor

public TestMethodTestDescriptor(UniqueId uniqueId,
 Class<?> testClass,
 Method testMethod,
 Supplier<List<Class<?>>> enclosingInstanceTypes,
 JupiterConfiguration configuration)

Method Details

withUniqueId

protected TestMethodTestDescriptor withUniqueId(UnaryOperator<UniqueId> uniqueIdTransformer)

Description copied from class: JupiterTestDescriptor

Returns shallow copy (without children) of this descriptor with the supplied unique ID.

Specified by:

withUniqueId in class JupiterTestDescriptor

Returns:

shallow copy (without children) of this descriptor with the supplied unique ID

getType

public TestDescriptor.Type getType()

Description copied from interface: TestDescriptor

Determine the TestDescriptor.Type of this descriptor.

Returns:

the descriptor type; never null.

• TestDescriptor.isContainer()
• TestDescriptor.isTest()

prepare

public JupiterEngineExecutionContext prepare(JupiterEngineExecutionContext context)

Description copied from class: JupiterTestDescriptor

Must be overridden and return a new context with a new ExtensionContext so cleanUp() does not accidentally close the parent context.

Specified by:

prepare in interface Node<JupiterEngineExecutionContext>

Specified by:

prepare in class JupiterTestDescriptor

See Also:

• Node.cleanUp(EngineExecutionContext)

prepareExtensionContext

protected void prepareExtensionContext(ExtensionContext extensionContext)

populateNewExtensionRegistry

protected MutableExtensionRegistry populateNewExtensionRegistry(JupiterEngineExecutionContext context)

execute

public JupiterEngineExecutionContext execute(JupiterEngineExecutionContext context,
 Node.DynamicTestExecutor dynamicTestExecutor)

Description copied from interface: Node

Execute the behavior of this node.

Containers typically do not implement this method since the HierarchicalTestEngine handles execution of their children.

The supplied dynamicTestExecutor may be used to submit additional dynamic tests for immediate execution.

The default implementation returns the supplied context unmodified.

Parameters:

context - the context to execute in

dynamicTestExecutor - the executor to submit dynamic tests to

Returns:

the new context to be used for children of this node and for the after behavior of the parent of this node, if any

See Also:

• Node.before(C)
• Node.after(C)

cleanUp

public void cleanUp(JupiterEngineExecutionContext context)
             throws Exception

Description copied from interface: Node

Clean up the supplied context after execution.

The default implementation does nothing.

Specified by:

cleanUp in interface Node<JupiterEngineExecutionContext>

Overrides:

cleanUp in class JupiterTestDescriptor

Parameters:

context - the context to execute in

Throws:

Exception

See Also:

• Node.prepare(EngineExecutionContext)

invokeTestMethod

protected void invokeTestMethod(JupiterEngineExecutionContext context,
 Node.DynamicTestExecutor dynamicTestExecutor)

nodeFinished

public void nodeFinished(JupiterEngineExecutionContext context,
 TestDescriptor descriptor,
 TestExecutionResult result)

Invoke testSuccessful(), testAborted(), or testFailed() on each registered TestWatcher according to the status of the supplied TestExecutionResult, in reverse registration order.

Parameters:

context - the execution context

descriptor - the test descriptor that was executed

result - the result of the execution
