Скачать или смотреть A Comprehensive Guide to Integration Testing in .NET Using Testcontainers [Arabic]

This video provides a detailed, step-by-step tutorial on implementing integration tests for a .NET application. The presenter begins by explaining the importance of integration testing to ensure that new code changes don't introduce regressions in a production environment. He illustrates the entire lifecycle of a test request, from the initial call through middleware, business logic, and interactions with external dependencies like databases and APIs.
It focuses on using the TestContainers library to create isolated, ephemeral Docker containers for dependencies, including a SQL Server database and mock external services using WireMock. it walks through setting up a dedicated test project, installing the necessary NuGet packages, configuring a custom WebApplicationFactory to override production services, and structuring the test environment using xUnit fixtures. Finally, it demonstrates how to write and run tests for both success and failure scenarios, proving how this setup can catch breaking changes before they reach production.
