Demo lack of error report.

Demo of #288

Tests are only run on a PR, so here is one to demo the test failure without an error report.

I had to really puzzle this one out, and I'm still not 100% on why the logs weren't getting printed. It looks like the problem is mostly related to mismatching after(:each) with before(:all) -- I was using :all to avoid building the executable multiple times, and I think I have a better solution on my local branch now.

As you will see in #294, I'm very interested in avoiding duplicate compiles. I'm not sure how this ties in but I'm glad you are working on it!

I'm curious if this fixes the issue for you locally 22e514d

In my local macOS environment, this is what I get now:

Unit testing foo.cpp with g++ for uno...

  ^~~
  for
/Users/jfoster/Documents/Arduino/libraries/TestSomething/test/foo.cpp:6:6: error: expected '(' after 'for'
  foo;

2 errors generated.

So that is a useful error report.
