/**\file
|
|
* Test that the captured stdout/err in (partial) testCaseEnded events
|
|
* is correct (e.g. that the partial test case event does not get accumulated
|
|
* output).
|
|
*
|
|
* This is done by having a single test case that is entered multiple
|
|
* times through generator, and a custom capturing reporter that knows
|
|
* what it should expect captured from the test case.
