Re: [Cppunit-devel] Logging.

[Baptiste L. <gai...@fr...>]

A clean way to do this would be to redirect cout TestListener::startTest(),
and capture what was outputted by the test in TestListener::endTest(). The
capture could be associated to the test and use at a latter time.

Does anyone know if it is possible to redirect to an strstream (I guess not,
but it would be nice) ?

But are you sure you need log ? Wouldn't more advanced, specialized, or
verbose assertions do the job ?
If you need a log, it usually means that you need to back in time. If that
is the case, it is likely that your unit tests are too complex (likely more
akin to functional test).
