BUnit
bUnit is a testing library for Blazor components that make tests look, feel, and runs like regular unit tests. bUnit makes it easy to render and control a component under test’s life-cycle, pass parameter and inject services into it, trigger event handlers, and verify the rendered markup from the...
Overview
bUnit is a testing library specifically designed for Blazor Components. Its main purpose is to make it easier to write comprehensive and stable unit tests for Blazor components. With bUnit, developers can set up and define components under test using C# or Razor syntax, verify outcomes using a semantic HTML comparer, interact with and inspect components, pass parameters and inject services, and mock various dependencies such as IJSRuntime, Blazor authentication, and authorization. The library builds on top of existing unit testing frameworks like xUnit, NUnit, and MSTest, allowing Blazor component tests to be run in the same way as any regular unit test. Compared to browser-based UI tests, bUnit runs tests in milliseconds instead of seconds.
Features
- Setup and Define Components: bUnit allows developers to set up and define components under test using both C# and Razor syntax.
- Semantic HTML Comparer: The library provides a semantic HTML comparer to verify outcomes of Blazor component tests, making it easier to ensure the correctness of rendered HTML.
- Interact with and Inspect Components: With bUnit, developers can interact with and inspect components, as well as trigger event handlers during the testing process.
- Pass Parameters, Cascading Values, and Inject Services: The library supports passing parameters, cascading values, and injecting services into components under test, enabling comprehensive testing of various scenarios.
- Mock Dependencies: bUnit allows developers to mock dependencies such as IJSRuntime, Blazor authentication, and authorization, enabling isolated testing of components.
- Integration with Existing Unit Testing Frameworks: The library seamlessly integrates with popular unit testing frameworks like xUnit, NUnit, and MSTest, allowing Blazor component tests to be run in the same way as regular unit tests.
Summary
bUnit is a powerful testing library designed specifically for Blazor Components. It provides an easy and comprehensive way to write unit tests for Blazor components, allowing developers to set up, define, and interact with components, mock dependencies, and verify outcomes using a semantic HTML comparer. The library seamlessly integrates with popular unit testing frameworks like xUnit, NUnit, and MSTest, making it a versatile choice for Blazor component testing. With its fast execution speed and efficient testing capabilities, bUnit is a valuable tool for ensuring the stability and correctness of Blazor components.
