JUnit timeout on @BeforeClass

Question

Tests in JUnit, annotated with @Test can have a timeout set in ms, for example:

@Test(timeout = 1000)
public void testSomething(){
    ....
}

However, I can't seem to find a way to put a timeout on the setup (or @BeforeClass).

Is there any other sensible way to do this? I wonder if there is some reason @BeforeClass cannot have a timeout?

I would like to do this:

@BeforeClass(timeout = 1000) // <-- Not currently possible
public static void setup(){
    doSomethingWhichMayRunForever();
}

Edit: added 'static'

Answer 1

I found some code related to the same in gitHub below. I had a scenario in our application as well to have timeout in @BeforeClass. I read its not a good practise to have conditions / logic added in @BeforeClass based annotated method. So, i handled condition in each @Test method.

See the link if it helps :

Answer 2

In JUnit marking the whole class for timeout is not possible .

In TestNG you can achieve that by anotating the test class with @Test annotation:

@Test(timeOut = 500)
public class Mavenproject1Suite {...}

在JUnit中，用@BeforeClass注释的方法必须是静态的，我想知道如果没有它，如何可以执行您的方法
