How to fix/workaround the error: "ERROR InitialTestExecutor Initial test run timed out" at Stryker 3?

[ralves20]

Question Hi!

I'm using Stryker 3 at the project that I work (unfortunately due to some project restrictions I cannot upgrade the stryker version), and when I try to run the stryker, I keep getting this error.

ERROR InitialTestExecutor Initial test run timed out!

What can I do to fix or workaround this error? I saw that there is the "dryRunTimeoutMinutes" but it is not available at stryker 3.3... so how can I workaround this issue on stryker 3?

Stryker environment

"@stryker-mutator/core": "3.3.1",
"@stryker-mutator/jest-runner": "3.3.1",
"@stryker-mutator/typescript": "3.3.1",
"jest": "24.9.0",
"typescript": "3.2.2"

I'm using the jest runner

How long do regular unit tests take to run?

The only think you can do is to configure jest to run less tests:

{
  "jest": {
    "config": {
      "testMatch": [ "only/one/file.spec.js" ]
    }
  }
}

Since you're using Stryker V3, coverage analysis isn't supported for jest (it's "off"), so you might want to limit the amount of files being mutates as well, so only the files being tested are mutated.
