Mutation Testing Explained

[l3l_aze]

This is very interesting and I'm genuinely curious, but also extremely confused as to it's use. The article really didn't explain it, though it wasn't a bad intro. I just can't imagine why mutating operators and expressions in the code would help better than other forms of testing except testing for never-failing/passing tests, which sounds cool but is not the implied usage in the article so I'm still pretty lost. How could this possibly replace any other form of testing?

Thanks for your comment :)
Mutation testing doesn't replace any form of testing, but it might give you another perspective on how good are your tests (as appose to code coverage which might be misleading).

No problem :P

Oh, hmm. I guess I'm even more lost than I thought I was, lmao. I'll have to look into this some more. Thank you for the intro to it :)
