Editor's Notes

  1. Allow you to write code faster while increasing quality Elegantly simple Check their own results and provide immediate feedback Tests is inexpensive Increase the stability of software Developer tests Written in Java Free Gives proper understanding of unit testing
  2. General Rules for Unit Tests Keep tests small Each tests exactly one thing Make tests independent No side effects No order dependencies Don't hard-code things like filenames Want to be able to move tests around Use meaningful names Check results with assertion methods, not raw assert statements
