Getting started with testing in Blazor with bUnit
Blazor doesn’t have a native unit testing framework, so its great community came up with bUnit, which became the standard for testing Blazor apps.
bUnit allows you to write unit tests either in C# files or in Razor components, and it’s compatible with all the common testing frameworks, such as xUnit, NUnit, and MSTest.
While testing a component, bUnit renders the target component in isolation and provides a full simulation, such as passing parameters, cascading values, and injecting services. It also simulates interactions with the component, such as clicking buttons or triggering event handlers.
The component being tested is known as the Component Under Test (CUT). The term CUT is what we will use throughout this chapter to name the component that we are testing. The term CUT is derived from the term Service Under Test (SUT), which is a known term in testing software overall, not just UI components.
