.register_additional_observers(&block) ⇒ Object

Test::Unit uses listeners to notify the UI of test progress, failures, etc. That’s great, if you’re writing a new UI. But unfortunately, it doesn’t provide an easy way (that I could find) to add your own listeners (for things other than the UI). The only place that I see add_listener used anywhere in Test::Unit is in the UI classes (ui/*/testrunner.rb).

So how does one hook into Test::Unit to register/add a listener for things without writing a new UI? (Let’s assume we’re perfectly happy with the Test::Unit::UI::Console UI…)

They’ve provided some nice “events” (“channels”?) – like TestCase::STARTED, TestCase::FINISHED, TestResult::FAULT – but how do I register with Test::Unit that I want to be notified of those events too?

Also, add_listener is an instance method – how do you get inside of TestCase/TestRunnerMediator so that you have an instance?

I wanted to add my own listener callback. So that’s why I wrote this monkey patch… (If there’s an easier way, let me know…)

  • Test::Unit::TestCase::FINISHED – Seems to be called not when the entire TestCase has finished running (as the name would suggest) but after every test method in the TestCase…?

  • Test::Unit::UI::TestRunnerMediator::FINISHED – When all the tests for a whole suite have finished
