Results reporting is not useful

[ducky64]

According to the comments in TreadleBackend, report is called to dump VCDs. Is there another treadle API to do the same thing / cleanly close the backend? I think the reporting is purely a side effect.

My own preference is that unit tests shouldn't print anything except for a pass / fail unless the user enables debugging flags - automation is the goal and needing to read through the console dump defeats that purpose...

Yes, the alternative is to call tester.finish in TreadleBackend instead, as it will just flush the vcd and print nothing. So that should probably be done.

OTOH, While I agree with you that automation is a big goal, the other no less important one is to enable test driven development, which is non-automated and usually involves a lot of looking at the tests outputs. To emphasize this, testers2 will also be more and more a part of the bootcamp. I think users will be better served to see some obvious success message rather than the unixy
Process finished with exit code 0

I share @ducky64's preference here. I'd like to see the output as indistinguishable from scalatest. The only default reporting should be limited to standard scalatest testing information, scalatest methods (info, scenario, feature, etc.), and user-explicit printf. (I'd go one step further and turn off all the Verilator compilation junk, too.)

I think the ScalaTest framework test(...) should not print anything by default at the very least.
However, it might be useful to think of how we could allow the user to print additional debugging data - maybe test() should return a status object that could be directly printed to the console? Maybe RawTester should have a test() variant that has an integrated print, or returns useful directly-printable status?

I think that info currently doesn't print anything if used in testers2. It would be nice if this was supported as it seems to be the most canonical way to print additional information during a test. I use this pretty heavily in some of the newer FIRRTL testing and it makes the tests look pretty clean.
