Slowness when creating mutant for 200 test cases

[ParulRuchi]

I'm trying to run stryker.net for my solution in local which have 200 test cases. It is taking more then 1 hour to complete. Is it normal?

[rouke-broersma]

Yes this is normal. Test cases are not relevant, it's the amount of mutants that determine the test length.

@rouke-broersma Mutant creation on migration folder is causing performance then? I have excluded this folder from mutation. But do you any other way to avoid this?

[rouke-broersma]

Migrations should usually be skipped by default I thought since it's generated code right? How are you excluding the migrations from mutation? It doesn't look like it's working. Generating 77K mutants will take a very significant amount of time.

Added as below:

Also, added bug for this issue too #3290

[rouke-broersma]

Your since.ignore-changes-in config is wrong, it does not have a negation. You want a positive match for ignore-changes-in.

Even after the change, I can see the same result and mutation testing taking 30 min in local.
