Does not exit with correct exit code

[fatso83]

Usually a test runner that has failing test will have an exit code of non-zero (like 1) when exiting. This does not, meaning that when it fails one is unable to inspect the error code to determine if there were failing tests.

@rpgeeganage I am no longer able to modify the code at this point 😿 I am not even able to find out where the test runner starts. Some sprinkled comments here and there would have helped 😸

After trying to analyze this, I am guessing the reporter could keep some internal failure counter and then when Processor#task is finally finished it can ask the reporter for the failure count and exit with process.exit(1) if it is > 0?
