Xamarin的.如何在DatePicker组件上设置日期?

Question

我想在我的应用程序上写一些功能测试。我有一个简单的窗口上的DatePicker组件:

<DatePicker AutomationId="PlanWyborDaty" Date="{Binding Data, Mode=TwoWay}" Format="dddd, dd-MM-yyyy" Margin="8, 0" DateSelected="OnDateChange"  />

我在我的测试方法中尝试了这些代码:

app.Query(x => x.Marked("PlanWyborDaty").Invoke("updateDate", 2020, 9, 2));
app.Query(x => x.Class("DatePicker").Invoke("updateDate", 2020, 9, 2));

，但日期在选择器仍然是相同的。我找了很多，只找到了这些方法。什么好主意吗?

模拟器是Pixel 2 API 28 Android 9.0

首先，使用AutomationId=" DatePicker "添加DatePicker控件

<DatePicker AutomationId="datepicker" />

然后在UItest.cs中使用以下代码:

[Test]
public void DatePickerTest()
{
app.Tap(c => c.Marked("datepicker"));
SetDatePicker(new DateTime(2018, 1, 1));

}
public void SetDatePicker(DateTime date)
{
// needed to tap & thus select the items
string month = DateTimeFormatInfo.CurrentInfo.GetMonthName(date.Month);
string day = date.Day.ToString();
string year = date.Year.ToString();
if (platform == Platform.iOS)
{
//Invoke the native method selectRow() 
app.Query(x => x.Class("UIPickerView").Invoke("selectRow", date.Month, "inComponent", 0, "animated", true)); // brings month in scope
app.Tap(month); // actually selects month
app.Query(x => x.Class("UIPickerView").Invoke("selectRow", date.Day, "inComponent", 1, "animated", true));
app.Tap(day);
app.Query(x => x.Class("UIPickerView").Invoke("selectRow", date.Year, "inComponent", 2, "animated", true));
app.Tap(year);
} else // Android
{
app.Query(x => x.Class("DatePicker").Invoke("updateDate", date.Year, date.Month, date.Day));
app.Tap("OK");
}
}
