Testcontainers for .NET
Integrationstests i .NET mod ægte Docker-containere, på nuværende 4.x API'er
Virker med opsætning
Hvad det gør
En reference for writing Testcontainers for .NET integration tests: module selection, builder configuration, wait strategies, container networking, volume and file mapping, cleanup via Ryuk, and worked xUnit, NUnit and MSTest examples for Postgres, Redis, SQL Server with EF Core, Kafka and multi-container stacks. Udløses når du har brug for a real database or message queue in a .NET test instead of a mock, or when Testcontainers tests are flaky in CI.
Testrapport
Nothing here could be compiled or run: this machine has no .NET SDK and no Docker or Podman, and Docker is a hard prerequisite for every example in the file, so the output score is left at no-measured-difference rather than guessed at. What I could check, I checked against the library's own source at version 4.13.0: every API the skill uses exists, the Ryuk image tag it names matches the one hardcoded in ResourceReaper.cs, and the constructor pattern it teaches is the one that is still current — the parameterless PostgreSqlBuilder() that most blog posts and a from-memory answer still reach for is marked [Obsolete] "will be removed" in the shipped code. Its own claim of 65+ modules is a shade high, with 64 module projects in the repository, and one Kafka example pins a different image than the library default. Install is clean from a bare HOME and the file is a genuinely well-organised reference, but you need Docker running before any of it does anything.
