Unveiling the Power of Approval Testing

Janina Nemec

12:00 - 12:45, Tuesday 11th November CET

(Re-)Discover a versatile and lightweight testing technique

Discover Approval Testing, a versatile and lightweight testing technique. It is not only useful for testing previously untested legacy code but also to ensure the stability of your public interfaces.

Approval Testing is a method of testing, that can be used in any programming language without tooling support. It is best known for getting unknown legacy code under test coverage as a prerequisite to refactoring. But this is not where the usefulness of this technique ends.

In this talk, I will share with you what Approval Tests are, which software tools can support you in writing them, how they are traditionally used for legacy code refactoring, and why you should have them as a tool in your testing technique toolkit. Additionally, I will tell you the story of an incident in my team that ended in us using Approval Testing in an untraditional way to ensure the stability of our public interfaces. This will let you understand why you should also consider utilizing Approval Tests on top of your already existing tests.

In the second part of this talk, I want you to experience how to write an Approval Test by giving you a live coding example so you can start utilizing this tool instantly.
