Question

我写了简单的测试：

   func testTabs() {
        let tabbed = "\t"
        let spaced = "    "

        XCTAssert(tabbed == spaced, "Comparison is illegal")
    }

   func testTabs() {
        let tabbed = "\t"
        let tab = "    "

        XCTAssert(tabbed == tab, "Comparison is illegal")
    }

如果无法使用实际的＆＃39; 标签＆＃39;间距，它失败了4个空格，2个空格。因此，我将 \ t 的标签进行比较，但失败了。（也没有任何等同物）。

它应该有用吗？如果我想进行测试，我是否应该在字符串中使用标签？让我说明我的意思：

func generateSomeString() -> String {
    let array = ["Some","Stupid","People","Don't","Read","But","Comment"]
    let string = array.joined(separator: "\t")
    return string
}

func testStrings() {
    let string = generateSomeString()
    let expectedString = "Some    Stupid    People    Don't    Read    But    Comment"
    print(string)
    XCTAssert(string == expectedString, "Comparison is illegal")
}

标签和空格是空格，但不是一回事。

您可以将\t替换为预期的空格数，然后对其进行测试......
