Expected/desired behavior

That this inside a step definition be the nightwatch api.

I beg to differ.

Without the callback, subsequent steps begin to execute before the current step has finished, this causing failure of my tests.

Essentially I 'm not sure I see the point of a step definition that can’t make use of the nightwatch api?

At the moment I’m on a tight deadline where every minute I spend costs the client money. I’ve already spent far too much time trying to workout why my tests were failing…

Some of my step definitions absolutely require some kind of asynchronous behaviour, that should be either one of : a generator, a Promise or a callback.

For now I had to roll back to an older version of your library. where I won’t have beforeEach or afterEach support.

You can return promise in step definition. And it will async

this.Given(/^a user "([^"]*)"$/, function (name) {
    return fetch('http://another/api', {
      method: 'POST'
      body: { name },
    });
  });

Or you can you generators

this.Given(/^a user "([^"]*)"$/, function * (name) {
    yield fetch('http://another/api', {
      method: 'POST'
      body: { name },
    });
  });

Hope this helps. I will close the separately ceated issue #146
