In Codeception/Command/Run::execute() on line 66:
if ($codecept->getResult()->failureCount() or $codecept->getResult()->errorCount()) exit(1);

Codeception is exiting with a status code of "1" whenever any of the tests fail. This confuses CI frameworks like Bamboo (and presumably jenkins) into thinking that codeception itself failed.

Ideally even when errors have been detected the exit code should still be "0" so that CI frameworks know that Codeception executed the tests correctly, and then parse the results to see which tests failed or succeeded.

Thanks :)
