The unit tests documentation in the Contributor’s manual offers a good introduction to unit testing and some technical hints for writing them. However, I believe we could add more information and make it more easy to follow for newcomers (at least when I wanted to write and run some tests, I found it rather austere).

What I think can be be added/enhanced:

• how to run the tests (full suite, single tests)
• how to compile tests
• env variables that affect tests
• link to kde guide - good intro to qttest
