What's Changed

While this release had a major focus on stability, we managed to optimize the startup sequence and it should make your tests even faster!

Here is what it takes to have a Redis up and running with Testcontainers, end-to-end from the test's start to an instance ready to be connected:
Before (1.17.1): 2.4s
Before (1.17.2): 1.7s 🚀

And here is just the "initialize Testcontainers" measurements:

Before (1.17.1): 1102ms
Before (1.17.2): 928ms

How we did it? We noticed that we can cache a couple of Docker responses, plus also removed now obsolete (yet expensive!) disk space check.

What's Changed

Highlights

This new version of Testcontainers comes packed with many new features and quality-of-life improvements, so we appropriately bumped the version to 1.17.0.

🐝 New Module: HiveMQ (#4797) @YannickWeber

Having started its Open Source life as its own 3rd-party Testcontainers library, we are very happy to welcome HiveMQ into the main repository.
Now, using HiveMQ as part of your integration tests is as simple as a couple of lines of Java code:

@Container
HiveMQContainer hivemq = new HiveMQContainer(DockerImageName.parse("hivemq/hivemq-ce:2021.3"));
hivemq.start();

Mqtt5BlockingClient client = Mqtt5Client.builder()
    .serverPort(hivemqCe.getMqttPort())
    .serverHost(hivemqCe.getHost())
    .buildBlocking();

client.connect();

Check out the docs to learn more about its many features!

💀 Ryuk JVM mode (#4959) (#4960) @bsideup

Many Testcontainers user love the convenience Ryuk brings to Testcontainers: No matter what you do in your integration tests, Ryuk has got you covered and will cleanup all Docker resources created by Testcontainers after your test run is finished.

But some users operate Testcontainers in environments which do not support our container-based Ryuk implementation. So far their only option was to disable Ryuk alltogether.

Coming with this release, Testcontainers will now fallback to a JVM based resource-cleanup implementation in case of Ryuk being disabled.
While this won't be as robust as the Ryuk container based implementation in all circumstances, it is nevertheless a great addition and acts as a useful compromise.

📦 Dependency updates

What's Changed

Highlights

Testcontainers 1.16.3 includes many changes, but there are two key highlights in this release:

k3s module (#4582) @rnorth, @kiview

We've had plenty of feedback from users wanting to use Testcontainers to help test Kubernetes components.
In particular, this is useful for people developing Kubernetes controllers/operators, who need something more than just a mocked Kubernetes API.
In this release we're bringing the k3s module, which gives you a neat way to spin up the K3S lightweight Kubernetes inside of a container.
We believe that k3s hits a sweet spot for ease of use and performance, so is a good option for testing Kubernetes components.

Now, launching a lightweight single-node Kubernetes cluster within your tests is easy as:

K3sContainer k3s = new K3sContainer(DockerImageName.parse("rancher/k3s:v1.21.3-k3s1"));
k3s.start();

String kubeConfigYaml = k3s.getKubeConfigYaml();
ApiClient client = Config.fromConfig(new StringReader(kubeConfigYaml));

// now use `client` to talk to your cluster!

Check out the docs to find out more!

Selenium 4 compatibility (#4914) @GannaChernyshova, @tobiasstadler, @kiview, @rnorth

Selenium 4 was announced a while back, but we needed to make some changes to Testcontainers' Selenium/Webdriver module for compatibility.
We're happy to announce that these changes have now been made, so you can now use Selenium 4 with Testcontainers!

As part of this upgrade we have to drop compatibility with Selenium 2, but believe that this will not have any practical impact.

What's Changed

1.16.1 inadvertently introduced a race condition. This bug can potentially cause unstable builds in some environments, manifesting as port wait timeouts at container startup. We recommend upgrading to 1.16.2 or higher.

Testcontainers 1.16.1 has been released! 🎉

This release brings a lot of eagerly awaited new features and fixes, such as:

🔮 Better Oracle Database support

Thanks to the engagement of the community and @gvenzl's new Docker images for Oracle Database Express Edition we were able to update our OracleContainer module to ensure its compatibility with a wide range of Oracle XE versions.

And at the same time, thanks to the new images, we were able to re-integrate the Oracle module into our CI. This means we can verify compatibility for using Testcontainers with Oracle Database going forward.

☁️ New Azure Cosmos DB module

With the new Azure Comos DB module we finally added Azure to our list of cloud service testing facilities.
It is based on Microsoft's Azure Cosmos DB-Emulator and provides you with a way to do your integration testing without the need for an actual Azure service.

public CosmosDBEmulatorContainer emulator = new CosmosDBEmulatorContainer(
        DockerImageName.parse("mcr.microsoft.com/cosmosdb/linux/azure-cosmos-emulator:latest")
);

Please check out the module docs to learn how to use it for your integration testing needs.

⛴ Host port access for containers

For further improving the developer experience of our users, we added a new API to make hosts ports accessible to containers:

container.withAccessToHost(true)

You still need to use exposeHostPorts, as per the docs, but this can now be done after the container has started, thereby allowing new usage patterns in your tests.

🌪 Faster Cassandra startup

By making clever use of the configuration settings available in Cassandra, CassandraContainer will now start up to 3 times faster.
It is now also configured to be less resource hungry out of the box.

✨ Better startup performance for all containers

We found a couple of ways to improve the container startup performance for our users, no matter the Testcontainers module you use.
This comes through some internal changes with regards to how Testcontainers checks for open ports during container startup and will shave up to a couple of seconds from your test suite.

We are grateful for the ongoing support of our community and users and thank each of our awesome contributors!

What's Changed

Testcontainers 1.16.0 is here! 🎉

This release brings many small fixes and improvements; among them:

Better M1 Mac compatibility

Users of M1 Mac will be pleased to know that Testcontainers now falls back to pulling x86_64 images when ARM64 images are unavailable, meaning that Docker's QEMU compatibility mode will be used to run the image. It's not perfect - not every image runs under QEMU. However, this allows Testcontainers users with M1 Macs to use more images than they could previously.

If possible, users should use recently published images for their dependencies which have a native ARM64 variant, rather than relying on QEMU emulation.

Startup performance and reliability improvements

Some issues affecting container startup time and reliability (especially with Docker for Windows) have been fixed.

Additionally, this release uses the latest version of docker-java and uses an Apache HttpClient5 transport by default. This resolves bugs encountered by some users when the previous default transport (okhttp) relating to image pulling.

As always, thank you to our many users and contributors!

What's Changed

This release focuses on stability and compatibility:

• Docker 20.10 introduced a new version of the API, 1.41, where they removed quite a few deprecations, and we were using one of them. If you were getting "No such image: testcontainers/ryuk:0.3.0" - that's the cause.
• In 1.15.0, ImageNameSubstitutor was added to help dealing with Docker Hub's rate limits. 1.15.1 introduces a default implementation that automatically prefixes every image without the registry. See the docs for more details.
• docker-java was updated to the latest version that improves the BitBucket Pipelines compatibility, Windows path handling, Socket I/O and related thread stucking on recv.
• The MockServer module is now compatible with the latest version of the image (5.11.x) and got an improved wait strategy.
