bUnit

bUnit is a testing library for Blazor components. You can easily define components under test in C# or Razor syntax and verify outcome using semantic HTML diffing/comparison logic. You can interact with and inspect the component under test, trigger event handlers, provide cascading values, and inject services. bUnit also includes a complete fake implementation of Blazor's authentication and authorization logic, navigation manager, and JSInterop.

bUnit.core is the base library that provides support for testing Blazor components. You need to install bUnit.web as well to test web-based Blazor components.

bUnit.web is the web specific parts of bUnit, that enables you to easily test and verify the output of Blazor (web) component.

bUnit.xunit is an xUnit extension for bUnit, that provides a way for xUnit to run bUnit's razor-based tests, as well as other helpful extensions to make the testing experience better if you use xUnit for writing your tests.
