问题描述

我正在使用 JUnit 和 Selenium Webdriver.我想按照我在代码中编写它们的顺序运行我的测试方法，如下所示:

I am using JUnit and Selenium Webdriver. I want to run my test methods in order as how I write them in my code, as below:

@Test
public void registerUserTest(){
    // code
}

@Test
public void welcomeNewUserTest(){
    // code
}

@Test
public void questionaireNewUserTest(){
    // code
}

但它不起作用，它总是按这个顺序执行我的测试方法:

But it doesn't work, it always executes my test methods in this order:

welcomeNewUserTest()
registerUserTest()
questionaireNewUserTest()

如果我用后缀 Test 命名我的方法，我会在某处读到答案，然后 JUnit 会按照我在代码中对它们的排序方式执行它们.显然，这行不通.

I read an answer somewhere if I name my method with suffix Test, then JUnit would execute them in order as how I order them in code. Apparently, this doesn't work.

有什么帮助吗?谢谢

推荐答案

所以对于像这样的测试——步骤相互依赖——你应该真正将它们作为一个单元来执行.你真的应该做这样的事情:

So for tests like these - where the steps are dependent on each other - you should really execute them as one unit. You should really be doing something like:

@Test
public void registerWelcomeAndQuestionnaireUserTest(){
    // code
    // Register
    // Welcome
    // Questionnaire
}

正如@Jeremiah 下面提到的，有一些独特的方法可以使单独的测试无法预测地执行.

As @Jeremiah mentions below, there are a handful of unique ways that separate tests can execute unpredictably.

既然我已经说过了，这就是你的解决方案.

Now that I've said that, here's your solution.

如果你想要单独的测试，你可以使用 @FixMethodOrder 然后按 NAME_ASCENDING 执行.这是我知道的唯一方法.

If you want separate tests, you can use @FixMethodOrder and then do it by NAME_ASCENDING. This is the only way I know.

@FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class TestMethodOrder {

    @Test
    public void testA() {
        System.out.println("first");
    }
    @Test
    public void testC() {
        System.out.println("third");
    }
    @Test
    public void testB() {
        System.out.println("second");
    }
}

将执行:

testA(), testB(), testC()

在你的情况下:

@FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class ThisTestsEverything{

    @Test
    public void T1_registerUser(){
        // code
    }

    @Test
    public void T2_welcomeNewUser(){
        // code
    }

    @Test
    public void T3_questionaireNewUser(){
        // code
    }

}
