dotnet-integration-testing

What problem does it solve?

This Skill enables robust integration testing for .NET applications by leveraging real infrastructure components like databases and external services, ensuring your application behaves correctly in a production-like environment.

Core Features & Use Cases

• In-Process API Testing: Use WebApplicationFactory to test ASP.NET Core APIs without network overhead.
• Containerized Infrastructure: Employ Testcontainers to spin up real databases, message brokers, and other services in Docker containers for isolated testing.
• Orchestrated Testing: Utilize .NET Aspire's testing capabilities to validate multi-service applications and their interactions.
• Database Fixtures: Manage database state with strategies like transaction rollback or data respawning for clean test environments.
• Use Case: Test a web API that relies on a PostgreSQL database by spinning up a PostgreSQL container with Testcontainers, configuring WebApplicationFactory to use that container's connection string, and then running API endpoint tests against the in-process test server.

Quick Start

Use the dotnet-integration-testing skill to create a new integration test class for an ASP.NET Core API using WebApplicationFactory and Testcontainers for PostgreSQL.
