UI 测试删除文本字段中的文本 [英] UI Test deleting text in text field

问题描述

在我的测试中，我有一个文本字段，其中包含预先存在的文本.我想删除内容并输入一个新字符串.

In my test I have a text field with a pre-existing text. I want to delete the content and type a new string.

let textField = app.textFields
textField.tap()
// delete "Old value"
textField.typeText("New value")

使用硬件键盘删除字符串时，没有为我生成任何录音.用软件键盘做同样的事情后，我得到了:

When deleting string with hardware keyboard Recording generated for me nothing. After doing the same with software keyboard I got:

let key = app.keys["Usuń"] // Polish name for the key
key.tap()
key.tap() 
... // x times

或

app.keys["Usuń"].pressForDuration(1.5)

我担心我的测试依赖于语言，所以我为我支持的语言创建了这样的东西:

I was worried that my test is language-dependent so I have created something like this for my supported languages:

extension XCUIElementQuery {
    var deleteKey: XCUIElement {
        get {
            // Polish name for the key
            if self["Usuń"].exists {
                return self["Usuń"]
            } else {
                return self["Delete"]
            }
        }
    }
}

代码看起来更好:

app.keys.deleteKey.pressForDuration(1.5)

但它非常脆弱.从模拟器退出后 Toggle software keyboard 被重置，我有一个失败的测试.我的解决方案不适用于 CI 测试.怎么解决才能更通用?

but it is very fragile. After quitting from Simulator Toggle software keyboard was reset and I've got a failing test. My solution doesn't work well with CI testing. How can this be solved to be more universal?

推荐答案

我写了一个扩展方法来为我做这件事，而且速度非常快:

I wrote an extension method to do this for me and it's pretty fast:

extension XCUIElement {
    /**
     Removes any current text in the field before typing in the new value
     - Parameter text: the text to enter into the field
     */
    func clearAndEnterText(text: String) {
        guard let stringValue = self.value as? String else {
            XCTFail("Tried to clear and enter text into a non string value")
            return
        }

        self.tap()

        let deleteString = String(repeating: XCUIKeyboardKey.delete.rawValue, count: stringValue.count)

        self.typeText(deleteString)
        self.typeText(text)
    }
}

这很容易使用:app.textFields["Email"].clearAndEnterText("[e-mail]")
