ASP.NET Core WebApi integration testing uses WebApplicationFactory to create an in-memory test server. This skill provides reusable test bases and implementation examples covering create, query, update, and delete API operations for end-to-end verification.

Yes, Testcontainers supports multi-container integration testing for ASP.NET Core WebApi. This skill enables containerized resources like PostgreSQL and Redis, providing deterministic test infrastructure with time control for reliable end-to-end API execution.

Validating ProblemDetails format and custom exception handling in WebApi integration tests is handled by testing IExceptionHandler implementations. This skill guides verifying global exception responses and validating ProblemDetails schemas using automated HTTP response assertions.

URL building and HTTP response verification in ASP.NET Core integration tests utilize Flurl for constructing requests and AwesomeAssertions for validating responses. This skill implements these tools to automate HTTP verification across common API operations.

No manual container setup is required before running dotnet test. This skill uses Testcontainers to automatically manage multi-container environments, providing deterministic test infrastructure that spins up containerized resources on demand for isolated execution.
