WidgetTestHarness class abstract base

class to subclass for any test that takes a WidgetTester

See ScreenTestHarness for setup of widgets with mixins

use UnitTestHarnessSetup to create a harness then pass it into the body of a test

 testWidgets('myTest', uiHarness((given,when,then) async {}))
final uiHarness = HarnessSetup.setupWidgetHarness(MyHarness.new);

class MyHarness extends WidgetTestHarness {
