Unable to use test-runner option in stryker4s config

[StasSuslov]

Hello!

I'm trying to use option test-runner in the stryker4s.conf file and while I'm launching stryker, I got this log message:

[info] Attempting to read config from stryker4s.conf
[warn] The following configuration key(s) are not used, they could stem from an older stryker4s version: 'test-runner'.
[warn] Please check the documentation at https://stryker-mutator.io/docs/stryker4s/configuration for available options.
[info] Attempting to read config from stryker4s.conf

I tried legacy runner with legacy-test-runner: true but it didn't help. Can someone please give me a hint on how to work around this problem?
It's a bit funny though: the log says I should check the configuration page, where I found this runner config.

Hi! What plugin of Strykers are you using? From your output I'm guessing sbt? The test-runner option is not a valid option for the sbt or maven plugin. It only works for the command-runner (which just executes the command). Are you getting any other exception or message that is preventing Stryker4s from running properly?

Hi! Yep, that's right, I'm using sbt-stryker4s version 0.16.1.
Oh, I see. Now my current flow is launch sbt and then run stryker with stryker cmd.
No, if I'm using plugin without any additional config everything's ok.
Btw, maybe you can give me a hit: I'd like to run Int tests instead of units. In case of this I tried test-runner option. Maybe there's a known way for this purpose?
