spot 0.10.0-beta.1

Chainable powerful finder API, screenshots and assertions for awesome widget tests.

Changelog

0.10.0-beta.1

Eventually Breaking, but only the class names. The end user API stays the same.

• spotSingle<W>() is now deprecated. Use spot<W>() instead, or spot<W>().atMost(1) to indicate that only a single widget is expected.
• WidgetSelector replaces SingleWidgetSelector and MultiWidgetSelector
• WidgetSelector now has a quantityConstraint property (deprecates expectedQuantity) that allows setting the min and max number of expected widgets.
• New: .atIndex(n) allows to get the widget at a specific index (when multiple are found)
• Fix: .first() and .last() now work after calling .copyWith()
• Breaking Quantity assertions like .doesNotExist() or .existsOnce() now return WidgetMatcher/MultiWidgetMatcher instead of WidgetSnapshot. To get the WidgetSnapshot use snapshot() instead.
• spotText('a') can now return multiple widgets
• Breaking remove WidgetSelector.cast because it lost information and was untested

0.7.0

• New prop API with hasWidgetProp() makes it easy to filter and assert properties of Widgets. This replaces the old hasProp() method which was based on way to complicated package:checks context.

  // Old ⛈️
  spotSingle<Checkbox>().existsOnce().hasProp(
      selector: (e) => e.context.nest(
        () => ['Checkbox', 'value'],
        (e) => Extracted.value((e.widget as Checkbox).value),
      ),
      match: (it) => it.equals(true),
    );
  

  // New ✨
  spotSingle<Checkbox>().existsOnce().hasWidgetProp(
      prop: widgetProp('value', (widget) => widget.value),
      match: (value) => value.isTrue(),
    );
  

  The prop API is also available for Element and RenderObject.

• Never miss asserting your WidgetSelector. All methods returning a WidgetSelector are now annotated with @useResult. This will cause a lint warning when you only define a WidgetSelector without asserting it.

  spot<FloatingActionButton>().withChild(spotIcon(Icons.add)); // warning, no assertion
    
  final plusFab = spot<FloatingActionButton>().withChild(spotIcon(Icons.add)); // ok, assigned
  spot<FloatingActionButton>().withChild(spotIcon(Icons.add)).existsOnce(); // ok, asserted
  

• It is now easy to directly access the Widget of a SingleWidgetSelector with snapshotWidget(). It also works for the associated Element and RenderObject. Use snapshotElement() and snapshotRenderObject().

  -final checkbox = spotSingle<Checkbox>().snapshot().widget;
  +final checkbox = spotSingle<Checkbox>().snapshotWidget();
  print(checkbox.checkColor);
