Swift XCUI 字符串断言失败 [英] Swift XCUI string assertion failing

问题描述

我正在使用 xcode 8.3.3 并编写 XCUI 测试.

I am using xcode 8.3.3 and writing a XCUI test.

我有以下几点:let address = XCUIApplication().buttons["URL"].value as!字符串

在调试器中查看，可以看到值是:

Looking in the debugger, I can see the value is:

如果我设置expectedURL = "\u{e2}auth.int....net" 然后它返回:

If I set expectedURL = "\u{e2}auth.int....net" then it returns:

如果我设置expectedURL = "auth.int....net" 然后它返回:

If I set expectedURL = "auth.int....net" then it returns:

如何让测试断言发现两个字符串相等?

尝试了以下操作，但它没有替换\u{e2}":

Tried the following, but it doesn't replace the "\u{e2}":

let address = value.components(separatedBy: ",").first!.replacingOccurrences(of: "\u{e2}", with: "")

还有(但它不会取代\u{e2}"):

And also (but it doesn't replace the "\u{e2}"):

let range = Range(uncheckedBounds: (lower: address.startIndex, upper: address.endIndex))

let strippedAddress = address.replacingOccurrences(of:"\\u{e2}", with: "", options: .literal, range: range)

对于断言，我使用 XCTAssertEqual(address, expectedURL)

推荐答案

您可以通过用字母数字字符分隔然后用空字符串连接来修复它，如下所示.

You can fix it by separating by alphanumeric characters and then joining by an empty string, as shown below.

let myString = address.components(separatedBy: CharacterSet.alphanumerics.inverted).joined(separator: "")

myString 则等于 authintxxxxxxxxxnet(没有."字符)，因此您应该能够更改预期的 URL 以匹配.

myStringis then equal to authintxxxxxxxxxnet (no "." characters), so you should just be able to change your expected URL to match.
