Hi! Thanks for opening this issue. I think this issue might be related to Java versions.
I can reproduce this issue by running Stryker with extra debug logging on the linked project with JDK 17, and see this in the output:
[debug] testrunner 13337: Test unsuccessful: users.controllers.UserUpdateTest status Error with OptionalThrowable(java.lang.IllegalAccessError: class com.typesafe.sslconfig.ssl.FakeKeyStore$KeystoreSettings$ (in unnamed module @0x5274766b) cannot access class sun.security.x509.AlgorithmId (in module java.base) because module java.base does not export sun.security.x509 to unnamed module @0x5274766b)

This looks related to some outdated libraries that don't properly work with the latest JDK. When I use JDK 11 or 8 Stryker4s runs fine without any errors. What JDK are you trying to run Stryker4s with? And is it possible there are other versions of your JDK installed that might be picked up?
If this doesn't sound like your issue, could you try adding debug { log-test-runner-stdout: true } to your stryker4s.conf and calling Stryker4s with debug logging by running sbt set stryker / logLevel := Level.Debug; stryker and seeing what extra logs you get?
Lastly, I think we can also improve on error logging with this. Because like you said NoSuchElementException: None.get is not very useful at all
I use JDK 8 on Stryker4s run, and it still give me errors. Enable debug as your suggestion helps me find unsuccessful tests. However, how could they be unsuccessful tests? All tests in the project are fine when I run sbt test.
It just doesn't feel right when I need to exclude unsuccessful tests out while running Stryker. The accuracy of mutation test result won't be correct, since the tests actually exist and some of mutants could have been killed by them.

I am also getting the same error in some of the modules after upgrading from 0.13.1 to 0.41.1:

Didn't seem to get unsuccessful test even by putting log in conf file.
PS. I was not getting this issue with v0.13.1
@hugo-vrijswijk I also got this but with scalapb. Is version 14 compatible with Scala Protocol Buffer from com.thesamet.scalapb:lenses_2.12:0.9.8?
