Async/blocking BeforeSuite, Before, After, AfterSuite hooks

What are you trying to achieve?

I would like to asynchronously create a test user and a test project over an XHR request before a collection of tests runs.

I expected one of the following to work:

BeforeSuite((I) => new Promise((resolve) => setTimeout(resolve, 5000)))
Before((I) => new Promise((resolve) => setTimeout(resolve, 5000)))

BeforeSuite(function* (I) {
  yield new Promise((resolve) => setTimeout(resolve, 5000))
})
Before(function* (I) {
  yield new Promise((resolve) => setTimeout(resolve, 5000))
})

What do you get instead?

Instead, the tests progress without any blocking/waiting. Is there any approach I can take to postbone test execution until my prerequisits are fulfilled?

Ok, promises are stored in a global promise chain. There is a way to access it (I will post it below, however it is not documented and not recommended to do so). To attach a promise to a promise chain it should be implemented as a method inside a helper and called inside a test:

BeforeSuite((I) => {
   I.doSomethingBeforeStart();
});

doSomethingBeforeStart should be defined inside a custom helper as a regular method returning a promise:

doSomething() {
    new Promise((resolve) => setTimeout(resolve, 5000))
}

Once the helper is enabled you can use its method inside Before/BeforeSuite.

Alternatively you can access a promise chain on your own

const recorder = require('codeceptjs/lib/recorder');

Before(function() {
   recorder.add(new Promise((resolve) => setTimeout(resolve, 5000)));
});

@sveneisenschmidt unfortunately I have not, I used a test to achieve what I wanted. Let us know if you find a solution!
