ConsoleTestListener provides feedback to the console, as test timings are taken, by drawing a '.', or an 'E', or an 'F', for each test that passes, is in error or fails. It does this for every test result registered with the framework, not just on the completion of each test method as the JUnit one does. It also uses a throttle to cap the rate of dot drawing, as exessively high rates can degrade test performance without providing much usefull feedback to the user. Unlike the JUnit dot drawing feedback, this one will correctly wrap lines when tests are run concurrently (the rate capping ensures that this does not become a hot-spot for thread contention).
Where rate capping causes the conflation of multiple requested dots into a single dot, the dot that is actually drawn will be the worst result within the conflation period, that is, error is worse than fail which is worse than pass.
