That's something I've always wanted to add, but never got the time...
My idea is an extension of this - it combines polling and assertions
in a single command, but it also has a maxWait duration, after which the
assertion would fail. The maxWait could be defined in user-extensions.js,
since you cannot pass many params from the tests.
We would then have:
pause '2000', assertTextPresent 'Value:1' -> waitAndAssertTextPresent 'Value:1'
pause '2000', verifyVisible 'autoId' -> waitAndAssertVisible 'autoId'
Another idea is to replace pause '2000' with a new waitForAjaxResponse
that:
- Adds a boolean responseArrived=false;
- Intercepts tacos.responseComplete to add code that makes
responseArrived=true
- Calls Selenium's doWaitForCondition('responseArrived==true')
I like this last solution. I would just use a custom doWaitForCondition
that also has the maxWait logic.
