Sure it can be pushed down the stack. It seems to me that this feature would be beneficial regardless of the testrunner and therefore well suited for the mutation test...

I don’t know all test tools, but the one I know allow me to specify which file to run the tests from. That’s all that’s needed isn’t it? Groetjes, Louis...

I have just now looked at the mutmut configuration feature. It seems to me that what you describe there should work if in this pre test callback the driver also...

@abingham Looking at the filter suggestion, I don't understand the idea. My understanding of the filter is that it runs after the init and removes some of the mutations from...

@boxed I have noticed that the set of mutations is indeed different, but that seems solvable with some analysis and additional plugins. Looking at hammett, I have difficulty in understanding...

@abingham I agree with you on that last bit. To get a complete verdict however, you need to have the results of the previous run available. I'm mainly thinking about...

So what are your thoughts on this feature and implementation? Does the feature make sense? And if so would a mutmut style interface with two callbacks make sense? ``` class...

@abingham I like that idea. Not sure that from a performance viewpoint creating another process in between is a smart thing. I guess one would like to batch this, but...

@boxed with mutmut I could run the tests. In my current environment which is clean from the repo, if I just pip install hammett and run hammett -x no tests...

@abingham Could you give me a pointer towards running pytest in-process. Seems a perfectly reasonable solution then... Sure. Will not report on mutmut here.
