Is there someone who use riverpod with convenient test ?

[Bazni]

Hi,

I'm implementing integration tests on my app, I tried the integration_test package but got an error with Riverpod and the same problem with convenient_test.

[fzyzcjy]

Hi, could you please show detailed errors? Then it will be easier to debug.

Btw from my experience, most GitHub Discussions have few readers (excluding repo creators).

Got Bad state: No element. My app isn't load when the test starts looking for elements.

Looks like showKeyboard has some trouble. So (without more information) I guess it may not be related to riverpod, but a more general issue with the test code. It would be great to make a minimal reproducible sample and sometimes the problem will be found.

[Bazni]

Is there a way to wait for the app to load or a way to wait for an element to show up? I got this error because I'm still in the splashscreen state.

[fzyzcjy]

Quoting flutter_convenient_test doc:

// OK even if "fetch data" needs undeterministic time interval. Will automatically pump, wait and retry.
await t.get(find.text('New Data')).should(findsOneWidget);

i.e. use something like this to await the widget to appear
