Less Than 30 Lines Of Code - MongoDB with Testcontainers in C#
MongoDB is an awesome document database that we can use from C# using the MongoDB Driver NuGet package. But what if you don't want to setup MongoDB Compass or deal with MongoDB Atlas? Is there an easy solution to just try out MongoDB locally, or even leverage it for testing purposes?
Testcontainers for MongoDB is the easy solution here! See how we can hook up Docker with MongoDB in less than 30 lines of pain-free C# code!

Well, We upgraded a very large, legacy monolith from .NET Core 3.1 (previously upgraded from .NET Framework 4.6.2) to .NET 7.0 three years ago, in about a week.
That included all Microsoft dependencies, file-scoped namespaces, and global usings. We ran into very few issues, mostly trivial compability issues, and since then we’ve kept it up to date with every new release, whether LTS or STS.
I mean, if we could do it, almost anyone can. 😀
P.S: To be fair, we did have a borderline-paranoid level of comprehensive unit tests, plus integration and functional tests backed by Testcontainers, so that probably helped a lot

What if we could easily spin up containers for services that our tests depend on?

The Testing Epiphany
Tracing this showed me that mocking an in-memory SQLite database for API tests is a trap. It hides structural production bugs.
The real move? Use Testcontainers to spin up a disposable PostgreSQL instance inside your Pytest suite.

any time I try to use Bun I end up regretting the decision, last week it was compatibility with testcontainers. At this point I don't see any single reason to prefer it over node (just like I don't see why I should use deno)

Spanner Omni を docker run で起動したくないから testcontainers から起動するフレームワークを作ったが、プロセスをまたいで共有したくなったのでライフサイクル管理をする機能を別に作るというやや本末転倒

New guest post by @eninkaduk: testing #Helm charts in ephemeral #k3s with @testcontainers for Go and #sk8s, and #OSS project by @Docker. The image-loading section is the trap everyone hits once.

Security is explicit, not implied: by default the host Docker socket is mounted (so Testcontainers works inside the sandbox) — that's root-equivalent host access.
RALPH_DOCKER_SOCK=0 turns it off. Full threat model in SECURITY.md.

🚀 Full room of Java devs for the 2h Microcks workshop @DevfestLille
A great session led by @seb2goxdev (@AXA) & @lbroudoux, exploring how to leverage Microcks @testcontainers to validate APIs & microservices.
Thanks to everyone who joined and shared their experiences 🙌

Who's actually using Floci?
Apache Camel. Just Eat. CrateDB. UK gov teams.
LocalStack went paid, they switched. Once Testcontainers, Spring Cloud AWS and Quarkus shipped Floci support, every downstream project got a one-line swap.
Community compounding.

I'm a core maintainer of @testcontainers for #go. Today I start a series on the library's internals.
Part 1 is how Run, GenericContainer, and functional options actually work.
