OPA Test: headless run error

xyla — Mon, 11 Dec 2017 10:06:11 GMT

Hi all,

I have some OPA tests, wich are successful if I run them manually in the browser, but fail (some of them) if I run them using a Grunt task and without a browser (headless).

Any idea what the problem could be? Any help would be appreciated!

Thanks,

The problem was that the OPA tests were made on elements which were dynamic. These elements are rendered only if the browser window is bigger than a certain size.

So the solution is to set a fixed screen size for PhantomJS in the gruntfile, qunit section (page->viewportSize):

qunit: {
            options: {
                '--web-security': 'no', // yes/no
                '--proxy': 'xxxxxx', //your proxy - if you have one
            },
            opa: {
               options: {
                page : {
                    viewportSize : { width: 1920, height: 1080 }
                },
                    urls: [
                        "http://<%= settings.connect.host %>:<%= settings.connect.port %>/test/integration/opaTests.qunit.html"
                    ],
                    // same as qunits timeout 90 seconds since opa test might take a while
                    timeout: "<%= tests.opaTimeout %>"
                }
            },

how you get the coverage report when you run headless? is is possible to share your code for grunt tasks for qunit and opa?

Thanks
