Extensions that implement TestInstancePostProcessor must be registered at the class level.

Method Detail

postProcessTestInstanceback to summary
public 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 java.util.Optional value from getTestInstance(). A TestInstancePostProcessor should therefore only attempt to process the supplied testInstance.

Parameters
testInstance:Object

the instance to post-process; never null

context:ExtensionContext

the current extension context; never null
