Nightmare timed out on CircleCI

circle.yml

#1

I have a Jest test that runs Nightmare fine locally but fails when deployed with CircleCI. Nightmare’s wait method times out for dynamic DOM elements on localhost (elements inserted into the DOM by Javascript after ajax requests). Below are versions of software I’m using along with sample code, errors, and logs. Let me know if I can include anything else to help you help me.

Solutions I’ve tried

  • Increase Jest’s timeout to 60 seconds
  • Increase Nightmare’s waitTimeout to 60 seconds
  • Verify that Nightmare’s wait method works for non dynamic elements and only times out with dynamic elements

Versions:
CircleCI: 2.0
Jest: 23.4.1
Nightmare: 3.0.1

Jest + Nightmare test code

    test('there should be a map legend', function(done) {
        jest.setTimeout(60000);
        const nightmare = Nightmare();
        nightmare
            .goto('http://localhost:3000/posts/explore-renewable-energy-around-the-world')
            .wait('.mapboxgl-choropleth-legend') // dynamic DOM element
            .exists('.mapboxgl-choropleth-legends') // dynamic DOM element
            .end()
            .then(() => {
                done()
            })
            .catch(done)
    })

Are you able to take a screenshot using these libraries? That’s what I find most useful in debugging browser tests.
