Default text reporter does not show names of failed tests about cgreen

[larsks]

Oh, I see the problem!

One of my tests calls code that generates a lot of output on stdout, so I called:

fclose(stdout);

While this doesn't suppress the general output from cgreen; it does suppress the individual test results.

Is there a "correct" way to suppress output from the code under test without suppressing output from cgreen?

Sorry, no, there is no officially supported way. The "normal" text-reporter prints to stdout, and it does it from the forked child process that runs the test. So closing stdout in the test will get you exactly the effect that you see.

However, there is a thing that you can try (I haven't), and maybe I shouldn't tell you this ;-)

There is an internal function, set_text_reporter_printer(), which is implemented to let Cgreen's own tests capture the output. It might be possible to use that if you want to make a temporary hack to redirect the Cgreen output from a specific test, to stderr for example.

The specifics can be seen in the beginning of src/text_reporter.c and since it's not supported you will have to copy the prototypes. You should call that function in the beginning of your test, and to do that you also need to get the reporter, which I think you can do with get_test_reporter().

But all of this is totally unsupported, may change at any time, and is also untested and unverified by me.
