- Use emojis instead of the pass/fail text
- Fix the new version of the script to run inside Serenity
- Don't print erroneous output after 'Output:'; start on a newline
instead
- Skip 'run-tests.sh' while testing
Previously, debugging a test with console.log statements was impossible,
because it would just cause the test to fail with no additional output.
Now, if the output of a test is not "PASS", the output will be printed
under the line where the test failed.
Empty output will have a special message attached to it -- useful when
a test author has forgotten to include `console.log("PASS")` at the end
of a test.
