      Refactor the test framework (#3622) · 91dd9699
      Ian Hickson authored
      * Refactor widget test framework
      
      Instead of:
      
      ```dart
        test("Card Collection smoke test", () {
          testWidgets((WidgetTester tester) {
      ```
      
      ...you now say:
      
      ```dart
        testWidgets("Card Collection smoke test", (WidgetTester tester) {
      ```
      
      Instead of:
      
      ```dart
        expect(tester, hasWidget(find.text('hello')));
      ```
      
      ...you now say:
      
      ```dart
        expect(find.text('hello'), findsOneWidget);
      ```
      
      Instead of the previous API (exists, widgets, widget, stateOf,
      elementOf, etc), you now have the following comprehensive API. All these
      are functions that take a Finder, except the all* properties.
      
      * `any()` - true if anything matches, c.f. `Iterable.any`
      * `allWidgets` - all the widgets in the tree
      * `widget()` - the one and only widget that matches the finder
      * `firstWidget()` - the first widget that matches the finder
      * `allElements` - all the elements in the tree
      * `element()` - the one and only element that matches the finder
      * `firstElement()` - the first element that matches the finder
      * `allStates` - all the `State`s in the tree
      * `state()` - the one and only state that matches the finder
      * `firstState()` - the first state that matches the finder
      * `allRenderObjects` - all the render objects in the tree
      * `renderObject()` - the one and only render object that matches the finder
      * `firstRenderObject()` - the first render object that matches the finder
      
      There's also `layers' which returns the list of current layers.
      
      `tap`, `fling`, getCenter, getSize, etc, take Finders, like the APIs
      above, and expect there to only be one matching widget.
      
      The finders are:
      
       * `find.text(String text)`
       * `find.widgetWithText(Type widgetType, String text)`
       * `find.byKey(Key key)`
       * `find.byType(Type type)`
       * `find.byElementType(Type type)`
       * `find.byConfig(Widget config)`
       * `find.byWidgetPredicate(WidgetPredicate predicate)`
       * `find.byElementPredicate(ElementPredicate predicate)`
      
      The matchers (for `expect`) are:
      
       * `findsNothing`
       * `findsWidgets`
       * `findsOneWidget`
       * `findsNWidgets(n)`
       * `isOnStage`
       * `isOffStage`
       * `isInCard`
       * `isNotInCard`
      
      Benchmarks now use benchmarkWidgets instead of testWidgets.
      
      Also, for those of you using mockers, `serviceMocker` now automatically
      handles the binding initialization.
      
      This patch also:
      
      * changes how tests are run so that we can more easily swap the logic
        out for a "real" mode instead of FakeAsync.
      
      * introduces CachingIterable.
      
      * changes how flutter_driver interacts with the widget tree to use the
        aforementioned new API rather than ElementTreeTester, which is gone.
      
      * removes ElementTreeTester.
      
      * changes the semantics of a test for scrollables because we couldn't
        convince ourselves that the old semantics made sense; it only worked
        before because flushing the microtasks after every event was broken.
      
      * fixes the flushing of microtasks after every event.
      
      * Reindent the tests
      
      * Fix review comments

      Remove size observers from scrollables. · f8080557
      Hixie authored
      Also:
       - add operator==/hashCode/toString to ViewportDimensions
       - add toString to BindingBase
       - add toString and debugFillDescription to ScrollBehavior
       - fix a bug in the RawGestureDetectorState's replaceGestureRecognizers
       - rename MixedViewport's onExtentsUpdate to onExtentChanged
       - replace ExtentsUpdateCallback with ValueChanged<double>
       - remove a microtask for dispatching scroll start, since it
         did not appear to have any purpose
       - added dartdocs to Instrumentation until I understood it
       - made all event dispatch in Instrumentation drain microtasks

      More resilient Widget tests · d041f3ea
      Hixie authored
      - force the time dilation to 1.0 for the Widget tests, so that a local
        change doesn't break all the tests during development.
      - add missing license block to all the files.
      - set ui.window.onBeginFrame to null when you use WidgetTester, so that
        the engine doesn't trigger any confusing frames after our fake frames.

      Fix scrolling of Block. · 59f7e7f0
      Hixie authored
      Since our build function depends on scrollBehavior.isScrollable, any
      time we update scrollBehavior we are implicitly updating our state. As
      such, we must do so during a setState() call, or else we won't rebuild
      and might not bother to listen to the scroll gestures.
      
      This probably broke when we made Block not listen to gestures if it
      wasn't overflowing.
