Most people say you can’t do Test Driven Development (TDD) on the frontend. They’re wrong. In this session, we will first level set on what TDD is and how to do it. Then we’ll immediately start applying TDD to Blazor using bUnit and the latest additions to bUnit I helped contribute to make TDD a breeze. We will even talk about if you can (and should) write tests for your CSS. All along the way, we will do live coding demos so that you can see TDD in action. While the demos will be using Blazor, the concepts apply to any frontend framework even in other languages.
