ios - 使用 TDD 在 Swift 中进行性能测试

Question

刚刚学习 Swift 中的测试驱动开发。我在“ProjectNameTests”组中创建了一个类，它是 XCTestCase 的子类。

    class BasicFunctionTest: XCTestCase {

        var values : [Int]?
        override func setUp() {
            super.setUp()
            // Put setup code here. This method is called before the invocation of each test method in the class.

        }

        override func tearDown() {
            // Put teardown code here. This method is called after the invocation of each test method in the class.
            super.tearDown()
        }

        func testExample() {
            // This is an example of a functional test case.
            XCTAssert(true, "Pass")
        }

        func testPerformanceExample() {
            // This is an example of a performance test case.
            self.measureBlock() {
                // Put the code you want to measure the time of here.
                for i in 1...100000{

                    println("ok i need to know the time for execution")


                }
            }
        }
}

我想对这些方法进行性能测试

func testPerformanceExample() {
    // This is an example of a performance test case.
    self.measureBlock() {
        // Put the code you want to measure the time of here.
        for i in 1...100000{

            println("ok i need to know the time for execution")


        }
    }
}

并想找出执行 for 循环的时间。我运行项目，转到 Product -> Perform Action -> Test Without Building。

我可以看到执行时间为 3.50 秒，但是当我尝试设置基线时，请点击描边区域，如下图所示:

我收到警告

Would you like to update the baseline values for all tests on all devices? You'll have a chance to review the changes the next time you commit to source control.

现在当我点击更新时，错误如下:

您能否检查 BasicFunctionTest 文件 Target 成员资格是否包括您的测试目标。您应该能够通过选择文件并导航到文件检查器(目标成员资格)来检查这一点。
