Introduction

Arquillian is a popular testing framework for Java applications that allows developers to write integration and functional tests. It simplifies the process of deploying applications to containers and provides a consistent API for interacting with the container.

Container orchestration platforms, such as Kubernetes and Docker Swarm, are widely used for managing and scaling containerized applications across a cluster. In this blog post, we will discuss how to execute Arquillian tests in a container orchestration platform to ensure the compatibility and reliability of your applications.

Prerequisites

Before getting started, make sure you have the following prerequisites in place:

• A container orchestration platform (e.g., Kubernetes, Docker Swarm)
• A Java application with Arquillian tests
• A container image for your application

Setting Up Arquillian Configuration

To execute Arquillian tests in a container orchestration platform, you need to configure Arquillian to use the remote container adapter. This adapter allows Arquillian to communicate with the container running in the orchestration platform.

You can configure the remote container adapter by adding the following dependencies to your project’s pom.xml file:

<dependency>
    <groupId>org.jboss.arquillian.protocol</groupId>
    <artifactId>arquillian-protocol-servlet</artifactId>
    <version>1.1.14.Final</version>
</dependency>
<dependency>
    <groupId>org.jboss.arquillian.protocol</groupId>
    <artifactId>arquillian-protocol-jmx</artifactId>
    <version>1.1.14.Final</version>
</dependency>

Running Arquillian Tests in a Container Orchestration Platform

To run Arquillian tests in a container orchestration platform, follow these steps:

1. Build the container image for your application using a tool like Docker or Kaniko:

   docker build -t my-application .
   

2. Push the container image to a container registry:

   docker push my-registry/my-application:latest
   

3. Deploy the container image to the container orchestration platform. The exact process may vary depending on the platform you are using. For example, with Kubernetes, you can use a deployment manifest (deployment.yaml) like this:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-application
spec:
  replicas: 1
  selector:
    matchLabels:
      app: my-application
  template:
    metadata:
      labels:
        app: my-application
    spec:
      containers:
      - name: my-application
        image: my-registry/my-application:latest
        ports:
        - containerPort: 8080

1. Once the application is deployed, you can run the Arquillian tests against the deployed container. Ensure that the necessary dependencies and configuration files are available in the test environment.

2. Execute the tests using a build tool like Maven or Gradle. For Maven, you can run the tests with the following command:

   mvn test
   

Conclusion

Executing Arquillian tests in a container orchestration platform provides an effective way to verify the functionality and compatibility of your applications in a distributed environment. By following the steps outlined in this blog post, you can easily configure and run your Arquillian tests against containers running in a container orchestration platform. Happy testing!
