Writing Programs That Write Tests: Better Testing With Scala

Writing tests is so . . . boring. And repetitive. And often, in hindsight, rather ad hoc, and therefore ineffective. We’ll learn about property-based testing using ScalaCheck: how it compares to unit testing, when is it better (or worse); learning about different families of invariants and when they are appropriate for your code; how to structure the tests using the main ScalaCheck abstractions, run them, and debug them; and how to test stateful systems. Don’t write tests! Write code that will write lots of tests!

Attendees will learn:

  • The differences between property-based testing and traditional unit testing
  • How to recognize the most common kinds of properties and encode them
  • How to structure, or refactor existing tests using ScalaCheck
  • Debugging strategies for tests
  • Testing strategies for stateful systems

Main audience: developers familiar with traditional unit testing, who want to learn more powerful techniques.
