Add an example to test Landscape orientation in a widget test #2005
Description
Activity
Orientation in testing is entirely different. See for example the last 2 links in the initial comment.
There is no easy to find way how to specify screen dimension/orientation for tests.There is no easy to find way how to specify screen dimension/orientation for tests.
This works just fine for me:
const double PORTRAIT_WIDTH = 400.0; const double PORTRAIT_HEIGHT = 800.0; const double LANDSCAPE_WIDTH = PORTRAIT_HEIGHT; const double LANDSCAPE_HEIGHT = PORTRAIT_WIDTH; final TestWidgetsFlutterBinding binding = TestWidgetsFlutterBinding.ensureInitialized(); await binding.setSurfaceSize(Size(PORTRAIT_WIDTH, PORTRAIT_HEIGHT)); await tester.pumpWidget(MyWidget()); // test in portrait await binding.setSurfaceSize(Size(LANDSCAPE_WIDTH, LANDSCAPE_HEIGHT)); await tester.pumpAndSettle(); // OrientationBuilder gets triggered // test in landscapeReacted by Ioana Alexandru- changed the title

@sethladd asked me how difficult it was to test landscape layouts in tests. I suspect it's straightforward to do, but I'm not aware of an example to give.

In practice all tests are landscape. :-)

It seems like we will want to explain to individuals in flutter.io/testing how to test landscape vs. portrait for their widgets (as well as layouts at different sizes). For our own widgets, coverage will tell us if we're testing the landscape vs. portrait configurations of course. e.g. https://coveralls.io/builds/11679479/source?filename=lib%2Fsrc%2Fmaterial%2Fdate_picker.dart#L101 (I'm not actually sure if that's telling me the portrait code is covered or not).

Indeed. Where's a good place to put this information? API docs? Where?
@eseidelGoogle commented on Thu May 25 2017
Presumably https://flutter.io/testing?

Probably a better way (not tested, wasn't aware of that before) https://stackoverflow.com/questions/53706569/how-to-test-flutter-widgets-on-different-screen-sizes
