How To Achieve 80% Code Coverage Fast And Painlessly - In Four Steps

80% of code coverage is a common number expected by QA departments. Such a metric is relatively easy to achieve:

  1. Test simple things first. The simpler, the better.
  2. Don't use asserts. They don't influence the code coverage and just break the build.
  3. Don't use fail, and do not re-throw exceptions - just swallow them.
  4. Sometimes you will have to split complex methods into smaller ones. Names don't matter. Its additional effort, but will increase your code coverage. Goto 1.

:-). Although I never saw all four items in the "field", the use of System.out.println instead of asserts becomes increasingly popular idiom. It is very easy to satisfy the QA department and write completely unmaintainable code at the same time :-).


Excellent! Bonus points for goto :)

It's a funny post but I dread ending up working with a dev team in the future that cites your bullet list as a practice they follow.
Would you make the smileys larger please? And maybe add a watermark with the text "This is funny. Laugh." in it?
