How can I improve my junit tests

Question

Right my junit tests look like a long story:

• I create 4 users
• I delete 1 user
• I try to login with the deleted user and make sure it fails

Answer 1

If you use TestNG you can annotate tests in a variety of ways. For example, you can annotate your tests above as long-running. Then you can configure your automated-build/continuous integration server to run these, but the standard "interactive" developer build would not (unless they explicitly choose to).

This approach depends on developers checking into your continuous build on a regular basis, so that the tests do get run!

Some tests will inevitably take a long time to run. The comments in this thread re. performance are all valid. However if your tests do take a long time, the pragmatic solution is to run them but not let their time-consuming nature impact the developers to the point that they avoid running them.

Note: you can do something similar with JUnit by (say) naming tests in different fashions and getting your continuous build to run a particular subset of test classes.
