Getting started with bUnit

To start writing tests for Blazor components, first set up a test project and then you can start adding tests.

The basic getting started topics are as follows:

  1. Creating a new bUnit test project covers setting up a bUnit test project.
  2. Writing tests for Blazor components covers the basics of writing tests for Blazor components.

The next level topics are:

  1. Providing different types of input to a component under test, e.g. passing parameters or injecting services.
  2. Verifying output in various ways from a component under test, e.g. inspecting the rendered markup.
  3. Mocking dependencies a component under test has, e.g. the IJsRuntime or HttpClient.
