Async tests with NightWatchJS - "TypeError: done is not a function"

[Monish Gupta]

I need to write some async tests for which I tried the example given in the NightWatchJs developer guide.

Example of async test from dev. guide:

module.exports = {

  'demo UnitTest' : function (client, done) {

    client.assert.ok('TEST');

    setTimeout(function() {

      done();

    }, 500);

  }

};

Getting TypeError: done is not a function. Full output:

Starting selenium server... started - PID:  3610

[Nightwatch Test] Test Suite

============================

Running:  demo UnitTest

 ✔ Passed [ok]: TEST ok

An error occurred while running the tests:

TypeError: done is not a function

    at null._onTimeout (/Users/guptam/Documents/repos/time-dfp/tests/automation/nightwatch-test.js:25:7)

    at Timer.listOnTimeout (timers.js:92:15)

Any pointers on the cause of above error? Thanks in advance. Please let me know if anything unclear.

You have to disable the automatic selenium session:

Thanks Andrei for the response.

But then, how do I start the selenium session from within the test? client.url is not defined in the test scope.

it's not possible to mix unit tests and UI tests.
