How to best test a data table configuration?

[daFish]

Hi there,

thanks for this bundle which is awesome to work with - even if it is rough around the edges. While working on a couple of data tables I questioned myself how to test these classes? Is there a service I can fetch from the container when writing a KernelTestCase?

Hey @daFish! Thanks for the kind words.

First, you could unit test the data table type class. There's no DataTableTypeTestCase yet, but easiest way would be to mock the DataTableBuilderInterface and pass it to the type's buildDataTable method. Then you could assert the table is built the way it was intended to.

Then, about integration tests - I think it should only test validity of the data table type class, since its registered as a service and may inject other services. Never bothered with it, but I may be wrong here.

I haven't written many application tests for data tables in my applications, though I don't think this requires any specific service. Just some assertions whether the response HTML contains records expected for that specific page. It may also test some interactivity (like sorting).

Thank you for the hints, @Kreyu. I'll use functional tests with assertions to cover my needs to now. Once this works and I have the time, I will try with mocking the interface.

I'll convert this issue to discussion if you need more help. Thanks!
