React Native finishes in timeout on splash screen while detox test

Question

Description

I have problem with timeout and I don't know why. It asks for permissions and then it set the permissions (probably). In this moment app looks loaded, but after that there will show black screen with spinner for a moment and then splash screen. In this moment the app is stuck.

I found few issues about timeout, but I tried a lot wrote there but nothing worked. My colleague tried to run Detox on the same project with the same package versions and it was without problem.Hhe had the same versions of React Native, XCode, Node, Mocha and Detox.

What I tried:

Few versions of Node: 8.1.3, 8.9.1 and 9.1.0
Reinstall Node
Delete and install node_modules again (yarn/npm)
Change Detox versions: 5.9.4 and 5.8.1
Change Mocha versions: 4.0.1 and 3.5.2
Delete and install App in ios simulator
upgrade XCode (9.0.1 –> 9.1)
Recreate detox builds,
Delete npm cache
Delete detox cache

Test:

describe('Permissions', () => {
  beforeEach(async () => {
    await device.launchApp({permissions: {
      notifications: 'YES',
      location: 'always',
    }});
    await device.reloadReactNative()
  });

  it('should have welcome screen', async () => {
    await element(by.id('searchCarsButton')).tap()
  })
})

Detox, Node, Device, Xcode and macOS Versions

Detox: 5.9.4, 5.8.1
Node: 8.1.3
Device: ios simulator
Xcode: 9.1
macOS: Sierra
React Native: 0.44.0

The error is actually giving you the problem. "For async tests and hooks, ensure "done()" is called;"

I believe your issue is that you are turning the functions into promises with the async and the test framework does not know when thet are done.

Remove your async/await and just use a normal .then() and when finished, call the done() function. That should end the test.
