Asserts that a SemanticsNode contains the specified information.

There are no default expected values, so no unspecified values will be validated.

To find a SemanticsNode directly, use CommonFinders.semantics. These methods will search the semantics tree directly and avoid the edge cases that SemanticsController.find sometimes runs into.

To retrieve the semantics data of a widget, use SemanticsController.find with a Finder that returns a single widget. Semantics must be enabled in order to use this method.

Sample code

testWidgets('containsSemantics', (WidgetTester tester) async {
  final SemanticsHandle handle = tester.ensureSemantics();
  // ...
  expect(tester.getSemantics(find.text('hello')), containsSemantics(label: 'hello'));
  handle.dispose();
});
