Junit: changing sequence of test running

Question

I have a big mess with 100 tests in one class and running all of them by clicking "Test project (...). They run in a random order and I would like them to run in a specific order - from beginning to the end, the same order that I wrote them. In eclipse it's not a problem because eclipse just works like that, how to do it in netbeans?

Any help will be appreciated.

Edit (due to answers): Tests order is required for the clearance of the log. They are independent.

How does order of tests matter? It is unlikely the IDE knows the order in which t you wrote the tests. — Jayan, Jul 12 '12 at 08:43

If your tests needs to run in a specific order, something is wrong with your design. 2 test that needs to run one after another are 1 test. Consider this before searching for a solution.

No, they don't "need to". It's required because of the clearance of the xml log. – Doszi89 Jul 12 '12 at 09:07

Having tests depending on other tests 99.9% of the time a very bad idea. Unit tests should be independent from each other, as otherwise you might have a cascade of errors, or (even worse) one test failing because something another test did sometime before.

If you still want to go through this pain, you'll need to use a different unit testing framework (such as TestNG - see dependsOnMethods) which supports test dependencies.

Junit doesn't support this feature because it's seen by many as a bad practice (for very good reasons).

My tests are independent. I need them in order because of clearance of xml log. Thank you for you answer, I consider using another environment, if there's no other way to solve it. – Doszi89 Jul 12 '12 at 09:10
Doszi, that clearance **is** a dependency. Can you think of a way of breaking it so the tests don't need to be run in a specific sequence? – Augusto Jul 12 '12 at 11:58

The next JUnit release will support ordering of test methods. The standard Maven Surefire Plugin supports ordering of test methods already.

Netbeans has good integration with ant build files. You could write a specific ant target that could execute each test in order.
