The blog post discusses transitioning from SQLite to Testcontainers for .NET to run integration tests for ASP.NET Core applications. The author encountered limitations with SQLite when running complex Linq queries. While alternatives like Mocking, EF Core In-Memory Database Provider, and LocalDB were considered, these were found to be wanting.
