A further problem was that jsdelivr.net only has vue-test-utils version 1.0.0-beta.11, which has a date of 11th Jan 2018?!?!
NPM is already at version 1.0.0-beta.29. So I switched to unpkg.com:
Now the wrapper which I get when I select the q-input finally has a
setValue function, and things are working MUCH better.
I still have to mess around with focusing the element, but that makes sense, because I’m using lazy rules.
wrapper.find(...).trigger("focus") doesn’t seem to work on a
The focus and blur process required in the test is complicated but lazy-rules just works that way, so I have no other choice:
- rules are not validated until the field is focused
- rules are not validated the first time until the field loses focus
- rules are continuously validated after returning to the field
In order to get the validation to fire after blurring the first time I had to do a “nextTick”, i.e. await on a
setTimeout(..., 0). I guess quasar/vue are waiting for some messages in the queue to be processed by the event loop. See the link to my example code below for more details.
Once you understand that and program the test to expect that behaviour, the test works quite well.
An example is here:
If you check that project out and serve https://github.com/maxant/kafka-data-consistency/blob/14f62badf13188ed153ae38de00aa9dc2042f27c/ui/tests.html using a simple web server like nodes http-server, you can see all the tests running in the browser, and you can see the components
wrapper.setValue(...) from vue-test-utils works fine with a
- same for
- if you use lazy-rules then expect to have to focus and blur the
wrapper.find(...).trigger("blur") or “focus” doesnt work => instead use native calls
- that might only work if the component is appended and actually visible in the browser… not sure
- my original question was whether quasar provided any utility functions to help test widgets, but I don’t currently believe any extra stuff is required - vue-test-utils suffices
Thanks for the help!
