Why should you test Blazor components – and how do you do it effectively?

In this talk, we dive into bUnit, a powerful testing library that makes unit testing Blazor components feel as seamless as testing plain C# objects. You’ll learn:
– The difference between browser-based and component-level testing
– How to write fast, maintainable tests using bUnit
– Best practices for mocking services, handling async code, and avoiding brittle DOM selectors
– Real-world examples with live coding

Whether you’re building a Blazor app or a reusable component library, this session will help you create stable and maintainable test suites.
