Test automation is all about feedback. Feedback that gives you quality updates about the features your team has built. A continuous green build is always the goal because this should give you the confidence you need to go to production. Unfortunately, I’m more used to a “traffic light build”, a build which passes and fails intermittently, mainly because of flaky tests. That is one of the worst things about end to end testing in my opinion.
Why on earth do we still put software into production when we can’t trust our test automation?! Well, that's because we retry the build a couple of times until we have a lucky hit: the build is green and we’re ready to go to production. Although this is a solution, it still feels like a pretty silly thing to do.
Another option, which has my preference, is refactoring those tests until they actually work. The annoying part about this is that you don’t know what’s going on, and most of the time it is impossible to reproduce the failures. Reproducing them takes a lot of time debugging, analysing and mostly guessing where the problem is.
What if we could actually see what’s going on?
