Determine whether this extension should receive a test-method scoped `ExtensionContext` during the instantiation of test classes or processing of test instances.

For `TestInstancePostProcessor`, use `testInstance.getClass()` to get the test class associated with the supplied instance. For `TestInstanceFactory` and `TestInstancePreConstructCallback`, use `TestInstanceFactoryContext#getTestClass()` to get the class under construction. For `ParameterResolver`, when resolving a parameter for a constructor, ensure that the `Executable` is a `Constructor`, and then use `constructor.getDeclaringClass()` to get the test class associated with the constructor. `getTestMethod()` is no longer empty, unless the `PER_CLASS` test instance lifecycle is used.

Determine whether this extension should receive a test-method scoped ExtensionContext during the instantiation of test classes or processing of test instances.

If an extension returns TEST_METHOD from this method, methods defined in the following extension APIs will be called with a test-method scoped ExtensionContext instead of a test-class scoped context. Note, however, that a test-class scoped context will always be supplied if the PER_CLASS test instance lifecycle is used.

InvocationInterceptor: only the interceptTestClassConstructor(...) method
ParameterResolver: only when resolving constructor parameters
TestInstancePreConstructCallback
TestInstancePostProcessor
TestInstanceFactory

When a test-method scoped ExtensionContext is supplied, implementations of the above extension APIs will observe the following differences.

getElement() may refer to the test method.
getTestClass() may refer to a nested test class.
- For TestInstancePostProcessor, use testInstance.getClass() to get the test class associated with the supplied instance.
- For TestInstanceFactory and TestInstancePreConstructCallback, use TestInstanceFactoryContext#getTestClass() to get the class under construction.
- For ParameterResolver, when resolving a parameter for a constructor, ensure that the Executable is a Constructor, and then use constructor.getDeclaringClass() to get the test class associated with the constructor.
getTestMethod() is no longer empty, unless the PER_CLASS test instance lifecycle is used.
If the extension adds a CloseableResource or AutoCloseable to the Store (unless the junit.jupiter.extensions.store.close.autocloseable.enabled configuration parameter is set to false), then the resource will be closed just after the instance is destroyed.
Extensions can now access data previously stored by a TestTemplateInvocationContext, unless the PER_CLASS test instance lifecycle is used.

Note

The behavior which is enabled by returning TEST_METHOD from this method will become the default in future versions of JUnit. To ensure forward compatibility, extension authors are therefore advised to opt into this feature, even if they do not require the new functionality.
