RailsConf 2022 - Testing legacy code when you dislike tests (and legacy code) by Maeve Revels

Are you supporting legacy code? Would you like to stop? A good testing strategy can transform legacy code into living code that is resilient and easy to evolve.

Learn why legacy code is so difficult to maintain and identify where tests can make the most impact. Not just any tests, though! We'll dive into the characteristics of high-value versus low-value tests and learn techniques for writing tests that minimize the cost of change.

Developers of any experience level can benefit from these concepts. Familiarity with Rails and an automated testing framework is helpful but not required.
