integration-testing

Integration testing for .NET APIs uses WebApplicationFactory to host an in-memory test server, enabling direct endpoint testing without external HTTP dependencies. This framework provides base classes and templates to configure and execute these HTTP requests against your API pipeline.

Yes, .NET integration testing supports Testcontainers to provision a live PostgreSQL database during test execution. This approach ensures your database interactions are tested against a real, isolated database instance managed entirely by Docker.

Resetting a PostgreSQL database between integration tests is handled by Respawn, which rapidly clears database state. This framework integrates Respawn to ensure each test runs in isolation without the overhead of dropping and recreating the database.

Simulating authenticated users in ASP.NET Core integration tests requires a TestAuthHandler to bypass normal authentication flows. This framework includes this handler to easily simulate authenticated users and specific roles during your API endpoint testing.

Yes, Docker is required because Testcontainers uses it to dynamically provision and manage the live PostgreSQL database instances. WebApplicationFactory handles the in-memory test server, but the database integration testing specifically relies on Docker containers.
