Stryker: How to execute a custom command for running tests instead of npm run test ?

[rbadr]

Question

Hello 👋

First, thank you for this great library 🙏

After reading the documentation, I didn't find a way to execute a custom command to run tests 😕 Basically when I run :
npx stryker run it uses npm test under the hood for running tests.

How can I customize the command to execute for running tests ?

For example let's say I want to ignore my integration tests, and want to run mutation testing only for unit tests, in this case I would like to execute the command npm run jest src/**/__unit_tests__/*.spec.ts

Thanks !

Stryker environment

"@stryker-mutator/core": "3.3.1",
"@stryker-mutator/jest-runner": "3.3.1",
"@stryker-mutator/typescript": "3.3.1",

"jest": "26.4.2",
"ts-jest": "26.4.1",

You can use

{
  "commandRunner": {
    "command": "jest src/**/__unit_tests__/*.spec.ts"
  }
}

I guess it is not yet documented. Sorry for that.
