问题 how do I test BottomNavigationBarItems via FlutterDriver ? FlutterDriver allows accessing Widgets via text , byValueKey , byTooltip and byType . But none of these methods work out for my App because of following reasons: text : The App is localized and I need to test the App in multiple languages. byValueKey : BottomNavigationBarItems do not have key properties. byTooltip : BottomNavigationBarItems do not have toolTip properties. byType : byType only returns the first match of the type and no

How to mimic a pressing ENTER on a TextField in Flutter Tests

由 感情迁移 提交于 2019-12-10 15:59:05
问题 Given that tester.enterText will allow me to enter the text on a TextField in a flutter test, how would I mock pressing the DONE key on the android keyboard or pressing ENTER on my keyboard inside the textfield? This would also be equivalent to checking for the pressing of the DONE button on the IOS/android keyboard 回答1: I found the implementation in the flutter repo tests @ https://github.com/flutter/flutter/blob/7e445a17324ee7e615ef2c886d0cb9407853f338/packages/flutter/test/widgets/editable

How to wait for a future to complete in Flutter widget test?

由 本秂侑毒 提交于 2019-12-04 05:40:22
I am trying to perform a widget test, specifically navigation test. I am using bloc architecture, setting a stream on the bloc triggers a series of events inside the bloc, gets session info from the server call (which returns a future of session info object), on successful server call a login stream is set and the widget has a stream subscription to this stream and navigates to the next screen.
