Training: Drupal Testing Crash Course


Writing tests is one of the best ways to guarantee quality software, prevent bugs, and produce clean and scalable code; yet many developers still don’t include tests with their code. Why?

  • “I don’t know how.”
  • "Writing tests is too hard."
  • “I don’t have time.”
  • “I don’t know what to test.”
  • “This code is too simple to need tests.”

What you'll learn

This training will address these common excuses and misconceptions, by presenting the actual value of employing test-driven development methodologies within your software development life cycle. Topics we'll cover include:
