I work for a very complex and configurable product and I need to improve testing strategy for it. I dont want to deep dive into each of numerous test cases created for it before - instead I want to rework or validate the whole testing strategy that was chosen. Maybe, I should apply ACC testing approach from Google, maybe there are better approaches, or maybe the only solution for my case is a brute force approach when we just generate as much test cases as possible.
Could you please recommend some book, site, interesting paper on this topic? I.e. how to choose a proper testing strategy for a product?
Or, maybe, you can recommend a great working approach for this that you have adopted.
