使用TDD在Swift中进行性能测试 [英] Performance testing in Swift using TDD

问题描述

在 Swift 中学习测试驱动开发。我创建了一个类，它是 XCTestCase 。

Just learning Test Driven Development in Swift.I created a class that is subclass of XCTestCase in the "ProjectNameTests" group.

    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")


                }
            }
        }
}

我想对这些进行性能测试方法

I want to perform performance testing of these method

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")


        }
    }
}

并想知道执行<$的时间c $ c> for loop.I在转到Product - > Perform Action - > Test Without Building时运行项目。

and want to find out the time for execution of the for loop.I run the project on going to Product -> Perform Action - > Test Without Building.

我可以看到执行时间为3.50秒，但当我尝试设置基线点击笔划区域时，如下图所示：

I can see the execution time as 3.50 sec but when i try to set the baseline clicking on the Stroke Area as below image:

我收到警告

您是否要更新所有
设备上所有测试的基线值？您将有机会在下次
提交源代码控制时查看更改。

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.

现在点击on更新错误如下：

Now when i click on Update the error is as below:

如何为我的特定方法设置基线时间这里

How can i set Baseline of the time for my specific method as Here

这是我的测试项目：

推荐答案

您能否检查BasicFunctionTest文件目标成员资格是否包含您的测试目标。您应该可以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。

Can you check whether BasicFunctionTest file Target membership includes your test target. You should be able to check this by selecting the file and navigating to File Inspector (target membership).
