Unit Testing Blazor Components with Moq and Bunit Unit testing in Blazor is essential to ensure that your components behave as expected. This article demonstrates how to effectively test Blazor components using Moq for mocking services and Bunit for rendering and interacting with components in a test environment. We’ll walk through various testing scenarios, including adding, fetching, updating, and deleting products in a Blazor application. Introduction to Bunit and Moq Bunit is a testing library designed for Blazor components. It allows you to render components in isolation and perform actions such as interacting with the UI, asserting the output, and verifying the behavior of the components. Moq is a popular .NET library for mocking dependencies in unit tests. It allows you to simulate the behavior of complex services and verify that your components interact with these services as expected. Testing Scenarios Let's explore several common scenarios where Bunit and Moq are used t
