Testrunner crashes with `TypeError: Illegal invocation`

[MareikeTaeubner]

Maybe I'm just using the runner wrong, but when I try to run the tests, jest crashes with this error:

 ● Test suite failed to run

        TypeError: Illegal invocation

          25 | electron_1.ipcRenderer.on("run-test", async (event, testData, workerID) => {
          26 |     try {
        > 27 |         const result = await (0, runTest_1.default)(testData.path, testData.globalConfig, testData.config, (0, resolver_1.getResolver)(testData.config, testData.serializableModuleMap));

Installed libraries:

• @kayahr/jest-electron-runner: 29.3.1
• jest: 29.4.1

This is my jest.config.js

module.exports = {
  // Indicates whether the coverage information should be collected while executing the test
  collectCoverage: true,

  // Indicates which provider should be used to instrument code for coverage
  coverageProvider: 'v8',

  // Allows you to use a custom runner instead of Jest's default test runner
  runner: '@kayahr/jest-electron-runner',

  // The test environment that will be used for testing
  testEnvironment: 'node',
};

Is there a way on my side to fix this?

Looks like you mixed up the setup. Either you are testing in the main process with the node environment, then you have to use @kayahr/jest-electron-runner/main as runner. Or you are testing in the renderer process with the @kayahr/jest-electron-runner test runner, then you have to use the @kayahr/jest-electron-runner/environment test environment. See the examples in the README.

ok, it is monday and the problem was sitting in the chair before the pc. ^^"

I completely overlooked the /main part. Thank you very much for helping me out.

It works fine now. Thank you again.
