If test is being directly executed (with stdout opened on the terminal) and the terminal capabilities indicate enough colors, then use the existing scheme of green, red, and blue to show when tests pass, fail or end in a different way.
When running the tests redirecting the stdout, for instance, to a file, then colors are not shown, thus producing a more readable output.
