* Registers custom listener that asks for captured stdout/err
|
|
*
|
|
* Running the binary with this listener, and asking for multiple _noncapturing_
|
|
* reporters (one would be sufficient, but that would also mean depending on
|
|
* implementation details inside Catch2's handling of listeners), we check that
|
|
* the listener gets redirected stdout, even though the reporters didn't ask for
|
|
* it.
