Onboarding to a 'legacy' codebase with the help of AI

"I think that the most confusing thing about testing is the word testing. We use it for many things, from exploratory testing and manual testing to unit testing and other forms of automation. The core issue is that we need to know that our code works, and we’ve lumped together a variety of practices and put them under this banner. We can look for some common strands between them but they are hard to find."

Even just this opening already resonates a lot. I feel similarly about the term "QA" where what we mean by testing (and/or QA) can often refer to a number of different tools, practices, and even people. And I feel like there's often a sort of kneejerk reaction around these topics before it's even clear what is actually meant by them.
