 For the most part, the KUnit core framework (what you use to write the tests)
 can compile to any architecture; it compiles like just another part of the

 KUnit is fast. Excluding build time, from invocation to completion KUnit can run
 several dozen tests in only 10 to 20 seconds; this might not sound like a big
 deal to some people, but having such fast and easy to run tests fundamentally
