Stryker initial run times out

Question

Running simply "stryker run", mutations are being created and everything seems to run smoothly, until i receive the error that the dry run failed:

22:19:29 (12628) DEBUG JestTestRunner Running jest with --findRelatedTests flag. Set jest.enableFindRelatedTests to false to run all tests on every mutant.

Just keep in mind that i receive Set jest.enableFindRelatedTests to false when in my config its true. If i set it to false the debuger wil say Set jest.enableFindRelatedTests to true. So thats why i removed it all together

this is my config:

/**
 * @type {import('@stryker-mutator/api/core').StrykerOptions}
 */
module.exports = {

    "!**/*test.ts"
  ],

Answer 1

In the Stryker configuration file, I have added the timeoutMS setting to increase the time each test uses. I set it to 30 seconds (30000).

timeoutMS: 30000   // Use extended timeoutMs for test run to remove Time Out Results

Answer 2

For the angular users In the documentation you can see two options for install use this npm install --save-dev @stryker-mutator/core

Then it will work
