- Method Detail
  - postProcessTestInstance
```
void postProcessTestInstance(java.lang.Object testInstance,
                             ExtensionContext context)
                      throws java.lang.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:
    
    java.lang.Exception
