Review comment:
Not sure if I understand your question. Action is pushed on stack in
`AbstractTagTest#createMocks` which happens on `setUp`, this isn't a full blown
action execution loop, rather tag tests mimic the whole execution logic.
Secondly, in `FreemarkerTemplateEngine` which is responisble for rendering
tags (and takes part in the test logic) there is a check
```
Object action = (ai == null) ? null : ai.getAction();
```
and I have no idea if this was because of some possible solution or just to
support testing - in normal situation `ActionInvocation` cannot be null and we
are triggering an exception in such situation (not sure if this was already
implemented in Struts 2.5.x).
I was trying to re-configure this tag test to use proper action execution
logic, but somehow I was ending up with two instances of the same action on the
stack, after spending a few hours I gave up and added the above assertions.
