How to test UITextField in Xcode UI Testing when the text field is empty?
提问by Anuj Kalra
I am making a UITestin Xcode. When I record my test it works fine but when I run the test, it gives an error.
我正在UITestXcode 中制作一个。当我记录我的测试时它工作正常，但是当我运行测试时，它给出了一个错误。
These are the lines of code where the error occurs:
这些是发生错误的代码行：
XCUIElement *clearTextTextField = [app.textFields containingType:XCUIElementTypeButton
identifier:@"Clear text"].element;
[clearTextTextField typeText:@"sheffield"];
The error says
错误说
UI Testing Failure - No matches found for textfield
UI 测试失败 - 找不到文本字段的匹配项
I imagine this is because my Text Field does not have any initial string and the tester cannot find a text box with initial string "Clear Text".
我想这是因为我的 Text Field 没有任何初始 string 并且测试人员找不到带有 initial string 的文本框"Clear Text"。
I watched the following tutorial on youtube.
The demonstrators code turns out fine because his textfield has an initial string. (At least that is what I think the problem is)
演示者代码结果很好，因为他的文本字段有一个初始字符串。（至少这是我认为的问题所在）
Is there a way to make the test work for empty text fields?
有没有办法让测试适用于空文本字段？

There are a few ways to do this.
有几种方法可以做到这一点。
If the textField has placeholder text you can use the placeholder text to find the textField.
You can use the
elementBoundByIndexmethod to get a textField at an index. i.e. If that is the only textField in the app at the time you can useXCUIApplication().textFields.elementBoundByIndex(0)
如果 textField 有占位符文本，您可以使用占位符文本来查找 textField。
您可以使用该
elementBoundByIndex方法在索引处获取 textField。即如果这是当时应用程序中唯一的 textField，您可以使用XCUIApplication().textFields.elementBoundByIndex(0)
to get the textField. (or whatever query you need to get that particular textField at that time)
获取文本字段。（或当时需要获取该特定 textField 的任何查询）
- You can set an accessibility identifier in code or in the storyboard to find the textField.
- 您可以在代码或故事板中设置可访问性标识符以查找 textField。
It is nice to use option 2 before setting up accessibility identifiers, so long as your textField is always going to be findable with the same query. Also, option 1 will fail if multiple textFields have the same placeholder text at the same time, so option 2 is even more appealing.
在设置可访问性标识符之前使用选项 2 很好，只要您的 textField 始终可以使用相同的查询找到。此外，如果多个 textField 同时具有相同的占位符文本，则选项 1 将失败，因此选项 2 更具吸引力。
