.NET Stryker - "since" flag doesn't seem to be doing anything

[nicholasamato]

Hello

When I run "dotnet stryker --since: (and here I am inputting the hash of the last commit), dotnet stryker doesn't seem to only mutate the changed code. Instead it still mutates everything. Am I doing something wrong?

I want to only do mutation tests on code that I changed, for example the diff that appears between the latest commit and the commit before it.

Please share the logs, they are most likely specifying why this is happening.

As you can see, only two files changed - both are test files, yet it is still finding mutants for the whole solution (there is 470 by default with the configuration I have).

I believe I see the issue now. It's because "a non c-sharp file" in the test project was changed as the log says. I removed the json change and now it works fine. Thanks for getting me to look carefully at the logs though.

For future reference is there a way to bypass this so it ignores non c-sharp changes when using --since?

You can use since ignore changes in
