public interface TestInstancePostProcessor

Common use cases include injecting dependencies into the test instance, invoking custom initialization methods on the test instance, etc.

Method Summary

Modifier and Type	Method and Description
void	postProcessTestInstance(Object testInstance, ExtensionContext context) Callback for post-processing the supplied test instance.

Method Detail

postProcessTestInstance

void postProcessTestInstance(Object testInstance,
                             ExtensionContext context)
                      throws Exception

Callback for post-processing the supplied test instance.

Note: the ExtensionContext supplied to a TestInstancePostProcessor will always return an empty Optional value from getTestInstance(). A TestInstancePostProcessor should therefore only attempt to process the supplied testInstance.

Parameters:

testInstance - the instance to post-process; never null

context - the current extension context; never null

Throws:

Exception
