Many developers have heard the term unit testing, but some might have nightmares about how complex it might be. That's why I enjoyed Thorsten Frommen's straightforward introduction to unit testing for WordPress. There are five questions that every unit test should answer:

  1. What are you testing?
  2. What should it do?
  3. What is the actual result (i.e., output, or return value)?
  4. What is the expected result?
  5. How can the test be reproduced?

Thorsten covers the common basic understanding and notes he'll be writing additional posts to go deeper.
