Full Testcontainers Experience

Unit Tests With Real Dependencies

Testcontainers is an open source framework for providing throwaway, lightweight instances of databases, message brokers, web browsers, or just about anything that can run in a Docker container.

Supports Most Popular Languages

GenericContainer redis = new GenericContainer("redis:5.0.3-alpine").withExposedPorts(6379);

container, err := testcontainers.GenericContainer(ctx, testcontainers.GenericContainerRequest{
    ContainerRequest: testcontainers.ContainerRequest{
        Image:        "redis:5.0.3-alpine",
        ExposedPorts: []string{"6379/tcp"},
        WaitingFor:   wait.ForLog("Ready to accept connections"),
    },
    Started:          true,
})

await new TestcontainersBuilder<RedisTestcontainer>()
    .WithDatabase(new RedisTestcontainerConfiguration())
    .Build()
    .StartAsync()
    .ConfigureAwait(false);

const redis = await new GenericContainer("redis:5.0.3-alpine")
    .withExposedPorts(6379)
    .withWaitStrategy(Wait.forLogMessage("Ready to accept connections"))
    .start();

What Our Users Are Saying

Frederik Hahne 🏠 💻

@atomfrede

Did I already say that @testcontainers is awesome? Of course I did, but if you get the chance to (early) access @AtomicJarInc‘s testcontainers cloud you should not hesitate to do so! It really “just works”, great piece of software!

Andy Wilkinson

@ankinson

I had the good fortune of being asked to beta test Testcontainers Cloud. It’s the real deal. Drop-in replacement for Docker Desktop and containers now start more quickly, both in Spring Boot’s own build and tests of various Boot-based apps that I maintain. Impressive start.

Rashidi Zin

@shidi

Our team was blessed to experience @testcontainers Cloud and it’s so easy to migrate. No more worries over dependency on dind.

Simon Vergauwen

@vergauwen_simon

I used @jetbrains Gateway only briefly but I can already see it’s the future of development. Most of us work on laptops but need to run multiple servers/containers just to locally develop some applications.

@testcontainers Cloud is another great example!

Cédric Champeau

@CedricChampeau

Got an exciting @micronautfw spike working:

start a build
runs tests which require a MySQL server
let Testcontainers Cloud spawn a container
let tests run in JVM mode
build a native image of the tests
run them against the same container

@QuarkusIO Dev Services and @testcontainers Cloud are a great match. Assuming we have 2 apps + #kafka just:

Run #testcontainers agent (no need local Docker)
Run both apps in dev mode – Kafka (shared between apps) starts on testcontainers cloud

@meistermeier

Friends of Docker wormholes in CI, I have bad news for you: I just threw @AtomicJarInc @testcontainers cloud support into the build config and things(tm) are just working.

@sivalabs

Today I got the opportunity to try out Testcontainers Cloud by @AtomicJarInc. It worked great with very minimal setup and I didn’t have such a pleasant experience with any new tool in the recent time.

Holy amazing wowsers! The best improvement to developer productivity since docker has landed. I got hands on with Testcontainers Cloud yesterday and it blew me away. Local dev, test, and CI will never be the same. Forever better. Thank you @AtomicJarInc !

Josh Long

@starbuxman

Replying to @nileshgule

@AtomicJarInc has a Testcontainers Cloud offering that’s in limited private beta but I bet they might be able to help you… 🙂

Nikita Salnikov-Tarnovski

@iNikem

Shout out to @AtomicJarInc! Thanks to their Testcontainers Cloud I was able to run the full test suite of @opentelemetry Java Instrumentation project on Apple Silicon. That was A LOT of different containers that still does not run on latest MBPs.

Vladimír Oraný

@musketyr

Simply wow. I’ve just got chance to test @AtomicJarInc @testcontainers cloud and still I can’t believe how simple is it to use 🙂

Michael Simons

@rotnroll666

I have to say, @QuarkusIO dev-services combined with @testcontainers in the cloud via @AtomicJarInc is brilliant.

No load for the containers on the local machine and config-free setup.

Expect more about it soon.

Oliver Libutzki

@OliverLibutzki

Had the opportunity to try #TestcontainersCloud. Here is the manual how to execute all your existing @testcontainers tests in the cloud:

Download Testcontainers Cloud Client
Start Testcontainers Cloud Client
Run tests

That’s it. That’s the manual.

Just amazing!

Max Rydahl Andersen

@maxandersen

This should be interesting! Ever since @quarkusio introduced devservices that uses

@testcontainers I’ve wondered how we could make it available for users without the machine power or even access to docker. Testcontainer cloud solves that problem.

Michael Simons

@rotnroll666

Are @testcontainers fast enough for TDD (test driven development)? I think yes, absolutely. Especially if you set them to reusable. Having only a thin client at hand but still want to use them? Using TC cloud from @AtomicJarInc makes this possible.

Sergei Egorov

@bsideup

“With @testcontainers Cloud, we run the backing containers for our integration tests in the cloud. There’s no change required for our test. […] I am convinced that this will drive the productivity (e.g., faster builds) for testing with Testcontainers even further.”
