自定义android datepicker库的UI测试

如何解决自定义android datepicker库的UI测试

我在我的 android 项目中使用这个库：

implementation 'com.github.florent37:singledateandtimepicker:2.2.7'

但是当我使用 Espresso 进行 UI 测试但是当像这样使用它时：

  onView(withClassName(Matchers.equalTo(SingleDateAndTimePicker::class.java.name))).perform(
            PickerActions.setDate(2021,6,30)
        )

或者那样

onView(withId(R.id.picker)).perform(PickerActions.setDate(2021,7,15))

它给了我这个错误

androidx.test.espresso.PerformException: Error performing 'set date' on view 'with class name: "com.github.florent37.singledateandtimepicker.SingleDateAndTimePicker"'.

或者这个错误

androidx.test.espresso.PerformException: Error performing 'set time' on view 'with id: com.test.testlist:id/picker'.

带有此错误详细信息：

 Caused by: java.lang.RuntimeException: Action will not be performed because the target view does not match one or more of the following constraints:(is assignable from class: class android.widget.DatePicker and is displayed on the screen to the user)Target view: "SingleDateAndTimePicker{id=2131230850,res-name=date_time_picker,visibility=VISIBLE,width=1038,height=604,has-focus=false,has-focusable=false,has-window-focus=true,is-clickable=false,is-enabled=true,is-focused=false,is-focusable=false,is-layout-requested=false,is-selected=false,layout-params=androidx.constraintlayout.widget.ConstraintLayout$LayoutParams@666160a,tag=null,root-is-layout-requested=false,has-input-connection=false,x=21.0,y=365.0,child-count=1}"

有什么解决办法吗？
