Five crimes against testing that I see repeatedly executed.
Testing and Quality are the same things
Just because you test, it doesn’t mean you have a quality product. Sounds obvious right? But why then is quality assigned to one person. Why have a Quality Gatekeeper? Testing shines a light on threats to quality.Testing does diddly squat if no developer fixes the problems, or no delivery manager allocates time for bug fixing and re-testing.
Testing is easy
Nope, testing is not easy. It might appear easy, and perhaps superficial testing is easy. Testing is a skilled activity requiring critical thinking, a solid understanding of context (be that business or technical and typically both), great communication and a host of other skills and traits.
Testing can be 100% automated
No. See above. Yes, you can automate parts of the execution, but humans design and evaluate plus a host of other activities. Critical thinking and problem-solving skills are essential parts of testing. Without them, you might as well automate a fish on a bicycle.
In the past, metrics have been the weapon of choice in crimes against testing. Test Case counts, DRE (Defect Removal Efficiency), pass/fail rates have all contributed to poor testing behaviour. Worse, they’ve often inhibited change due to dependencies on these metrics. Many testers have been burned badly by these metrics to the point where it’s stilted the conversation around quality metrics. The crime here is to throw out metrics altogether. Instead, why not have an informed discussion on the merits of metrics and quality?
Testing is a means to an end, not the end
It’s easy to get caught up in discussions on the merits of testing and checking. But ask yourself how this debate is helping your organisation deliver a quality product. Being right semantically is not the end result. Even Testing is not the end result. Your end result is a quality product. If you are a tester or quality advocate in your organisation, do you know what quality means in terms of business outcomes?
I bet you’ve seen a few crimes of your own. What would you add?
