如何使用 Junit 按顺序运行测试方法
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
}
}
