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

问题描述

刚刚在 Swift 中学习 Test Driven Development.我在ProjectNameTests"组中创建了一个类，它是 XCTestCase 的子类.>

 class BasicFunctionTest: XCTestCase {变量值:[Int]?覆盖 func setUp() {super.setUp()//把设置代码放在这里.在调用类中的每个测试方法之前调用此方法.}覆盖 func 撕裂(){//将拆卸代码放在这里.在调用类中的每个测试方法之后调用此方法.super.tearDown()}功能测试示例(){//这是一个功能测试用例的例子.XCTAssert(真，通过")}func testPerformanceExample() {//这是一个性能测试用例的例子.self.measureBlock() {//把你想测量时间的代码放在这里.对于我在 1...100000{println("好的，我需要知道执行的时间")}}}}

我想对这些方法进行性能测试

func testPerformanceExample() {//这是一个性能测试用例的例子.self.measureBlock() {//把你想测量时间的代码放在这里.对于我在 1...100000{println("好的，我需要知道执行的时间")}}}

并想找出 for 循环的执行时间.我运行项目，转到产品 -> 执行操作 -> 不构建测试.

我可以看到执行时间为 3.50 秒，但是当我尝试设置基线时，单击下图所示的描边区域:

我收到警告

您想更新所有测试的基线值吗?设备?下次您将有机会查看更改致力于源代码控制.

现在当我点击更新时，错误如下:

解决方案

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.

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")


                }
            }
        }
}

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")


        }
    }
}

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.

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:

I get warning as as

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.

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

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

解决方案

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).
