We all (should) use unit testing to test our code. But if we build a front-end application with Blazor, we also need to test the code running in the browser.

Well fortunately there is a tool to help us accomplice this: Playwright. In this talk I will show you what Playwright is and how you can use it to automatically test your Blazor front-end.
