Test cases and traffic lights: Is it a traffic violation?

Did you ever had a doubt whether you should make a test case fail or pass? Did you ever strayed off the beaten path of the written test case scenarios and found strange behaviours, and then had doubt what should be the outcome of this test? I believe every tester can answer this question with “Yes, thousands of time!”.

For years, I’ve been stuck in a mindset that test cases must resolve to “PASS” or “FAIL”, but then I realised: There are no traffic lights off that beaten paths, and it is not easy to decide whether to proceed or not (pass or fail). And the whole fun lies in this unexplored and unmarked paths in the jungle of code.

Let me guide you through this jungle by starting from my first baby steps as a “tester toddler”. It was very hard back then when I was learning to walk (test) at a first place. Lets walk together through my testing journey with the constant looking back on this thought: “What adds more value: subjective feeling, reliability of the software, or the number/percentage of the green, red, or even orange(yellow) test cases?” Can we find a parallel between executing tests and traffic lights?
