Xamarin.UITest:如何验证占位符/提示文本 [英] Xamarin.UITest: How To Verify Placeholder/Hint Text

问题描述

我正在为跨平台的Xamarin.iOS和Xamarin.Android应用程序编写Xamarin.UITest.

I am writing a Xamarin.UITest for a cross-platform Xamarin.iOS and Xamarin.Android app.

在我的Xamarin.UITest中，如何验证以下属性:

In my Xamarin.UITest, how do I verify the following properties:

• 在Xamarin.Android上，如何验证EditText的Hint属性?
• 在Xamarin.iOS上，如何验证UITextField的Placeholder属性?

• On Xamarin.Android, how can I verify the Hint property for an EditText?
• On Xamarin.iOS, how can I verify the Placeholder property for a UITextField?

推荐答案

示例代码

string GetPlaceholderText(string entryAutomationId)
{
    if (app is AndroidApp)
    {
        return app.Query(x => x.Marked(entryAutomationId)?.Invoke("getHint"))?.FirstOrDefault()?.ToString();
    }

    return app.Query(x => x.Marked(entryAutomationId)?.Invoke("placeholder"))?.FirstOrDefault()?.ToString();
}

示例应用

以下是示例应用中的相同代码段，该示例演示了如何在跨平台Xamarin.UITest:

Sample App

Here is the same code-snippet in a sample app that demostrates how to accomplish this task in a cross-platform Xamarin.UITest:

在Xamarin.UITest中，要从Android EditText或iOS UITextField检索文本，必须使用Invoke方法访问本机

In Xamarin.UITest, to retrieve text from an Android EditText or a iOS UITextField, you must use the Invoke method to access the native Java Android API and native ObjectiveC iOS API. In our Invoke statements, we can take advantage of the native methods (getHint() on Android, and placeholder on iOS) to retrieve the string.

所有测试均通过 Xamarin测试云进行了验证.测试报告是在此处可见.

All tests were validated via Xamarin Test Cloud. The test report is viewable here.
