Document how to write UI tests that interact with native UI elements

[felangel]

Since markers aren't widgets, what is the recommended way to write a widget test which taps a map marker and ensures that the onTap is executed? I didn't see any marker onTap tests in the google maps plugin tests 🙁

Thanks!

Hi @felangel , it seems a long time no answer here. Did you have any solution for this yet? I'm in the same situation here. Thanks

@hainguyen168 unfortunately, I don't think we ever came up with a solution :(

This would need to be done via espresso/XCUITest. Leaving open to track adding such a test to the plugin, both for improved test coverage and to provide an example of this kind of test for apps using the plugin.

Are there any updates about this?

I've tried tapping on the marker via tester.tapAt function and even if I hit the marker, onTap didn't seem to call. Does that mean that also tapAt triggers tap events only onto widgets? /cc @stuartmorgan

await tester.tapAt(Offset(mapCenter.dx, mapCenter.dy); // I hit the marker, but no reaction.

Flutter test events are injected at the Flutter layer, so have no effect on native views.

Patrol might help you with this. It can interact with platform views (i.e. not Flutter widgets).

Following this. Has anyone yet managed to get any kind of test that loads the map and able to interact with it, like clicking on a marker

For reference until there's actual documentation on this, some examples of hybrid UI tests in flutter/packages:

• Espresso
• XCUITest

Any update on this

You could try using Patrol to interact with non-native UI such as Google Maps markers and info windows.
