Many developers use Gen AI a lot for creating code. Generating unit tests is quite popular. But there is also a thing called test-driven development. And the major benefit of adopting this approach is not 100% code coverage, but rather a clean design. But can these approaches be applied together? During this session, we will dive into applying the combination for writing a piece of software. So at the end of this talk, you can make an informed decision whether TDD is useless if you use GenAI. Do not expect a lot of slides. We will spend most of our time in Rider en AI Assistant.
