如何与Junit一起按顺序运行测试方法 [英] How to run test methods in order with Junit

问题描述

我正在使用JUnit和Selenium Webdriver.我想按照我在代码中的编写方式来运行测试方法，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
}

但是它不起作用，它总是按以下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会按照我在代码中的排序方式依次执行它们.显然，这是行不通的.

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.

有帮助吗?谢谢

推荐答案

因此，对于此类测试(步骤彼此依赖)，您应该真正将它们作为一个单元执行.您实际上应该在做类似的事情:

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
}

就像@耶利米在下面提到的那样，有几种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.

现在我已经说过了，这是您的解决方案.

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

如果您要进行单独的测试，则可以使用 @FixMethodOrder ，然后按NAME_ASCENDING进行操作.这是我唯一知道的方法.

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()

在您的情况下:

@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
    }

}
