thrown: "Exceeded timeout of 120000 ms for a hook.

Thanks @gunnartorfis, I will go over the logs and the configurations you provided.

Also, regarding:

It also might be worth mentioning that when running the tests locally, Detox spins up a new simulator. For example, if I declare “iPhone 12” in my `.detoxrc.json’, that one will fire up but tests will run on “iPhone 12-Detox”. Not sure if that’s normal but wanted to mention that.

Try echo "[]" > ~/Library/Detox/device.registry.state.lock. That’s probably because the desired simulators are locked in this file. See: https://wix.github.io/Detox/docs/guide/parallel-test-execution/#lock-file

Each worker is responsible for removing the device ID from the list in device.registry.state.lock. Exiting a test runner abruptly (using Ctrl+C / ⌘+C) will not give the worker a chance to unregister the device from the lock file, resulting in an inconsistent state, which can result in creation of unnecessary new simulators.

It’s still behaving a bit weird, like it’s constantly restarting the simulator or something, eventually reaching an error thrown: "Exceeded timeout of 120000 ms for a hook. Use jest.setTimeout(newTimeout) to increase the timeout value, if this is a long-running test.".

environment.js:

const {
  DetoxCircusEnvironment,
  SpecReporter,
  WorkerAssignReporter,

class CustomDetoxEnvironment extends DetoxCircusEnvironment {
  constructor(config, context) {
    super(config, context);

    // Can be safely removed, if you are content with the default value (=300000ms)
    this.initTimeout = 300000;

    // This takes care of generating status logs on a per-spec basis. By default, Jest only reports at file-level.
    // This is strictly optional.
    this.registerListeners({
      SpecReporter,
      WorkerAssignReporter,
    });
  }
}

module.exports = CustomDetoxEnvironment;

init.js:

const detox = require('detox');
const config = './config.json';

  await detox.init(config);
  await device.launchApp();
});

afterAll(async () => {
