> But I'm not quite sure if there is a direct correlation between time spent writing tests and overall software quality?

Good point. We do not know, either. That is part of the reason why we do this research. :)

As has been said before, the easier to understand and maintain your tests are, the less amount of time you actually need to spend on them.

However, you could argue, that there must be some minimal amount of time that you absolutely need to spend on QA work like testing to ensure a certain quality.

We are investigating this.
