tester2 Jupyter Notebook test output

[blhguo]

I've noticed that when all the test cases pass, the notebook outputs

test xxx Success: 0 tests passed in xxx cycles in xxx seconds xxx Hz

While the same message appears even if a test fails, though now accompanied with an exception getting thrown. I'm not sure if this behavior is intended, but I think a successful run should display # of tests passed (alternatively, 0 tests failed), with test failure displaying number of failures.
