Running integration tests with Kubernetes

Integration test on Kubernetes with Jenkins pipeline

Blog post: https://itnext.io/running-integration-tests-with-kubernetes-ae0fb71e207b

Directories:

• app-users: Example Red Hat Fuse 7 application that takes messages from AMQ, makes database queries and calls a REST api
• configuration/settings.xml: Maven settings.xml with the requires repos to build
• integration-test: Tests written in Java with Junit, can be executed with Maven
• arquillian-test: Test with Arquillian Cube on OpenShift

Jenkins pipelines:

• Jenkinsfile: Builds app and executes integration test.
• Jenkinsfile-basic: Executes integration test only. Setting only the important parameters.
• Jenkinsfile-declarative: Using declarative syntax. Setting a different agent at stage level. Builds app and executes integration test.
• Jenkinsfile-declarative-one-agent: Using declarative syntax. Agent is defined at the pipeline level. Executes integration test only.
• Jenkinsfile-declarative-runas: Using declarative syntax. Pod sets runAsUser to make sure all containers are started with the same uid. No "umask 0000" is needed in the command. Requires 'anyuid' scc.
• Jenkinsfile-declarative-restricted: Using declarative syntax. Only works if 'restricted' scc is being used, so the same random uid is set for all containers. No "umask 0000" is needed in the command.
• Jenkinsfile-jnlp-base: Using separate container for jnlp and maven. Executes integration test only.
• Jenkinsfile-mavenlocalrepo: Mounting a persisted volume as maven local repository to avoid downloading jars every time. Requires a 'mavenlocalrepo' persistent volume claim. Builds app and executes integration test.
• Jenkinsfile-yaml: Reads yaml pod template from 'pod.yaml'. Builds app and executes integration test.
• Jenkinsfile-arquillian: Run the arquillian-test integration test project. See README.md in its directory.

App-users

A Spring Boot application running a Camel route based on the Red Hat Fuse 7 stack.

Steps:

• Take messages from user.in queue. Json :{"email": "[email protected]"}
• Query phone number from table users
• Call a REST api to get address. E.g. https://myhost/v1/address/email/[email protected]
• Send the enriched user info to queue user.out

Build and run unit tests with Maven:

• Use the provided settings.xml to access the required Maven repositories:

mvn -s ../configuration/settings.xml clean package

Integration-test

Tests written in Java using Junit5. Run with Maven: mvn clean test

Env variables required:

• AMQ_USER: AMQ connection username
• AMQ_PASSWORD: AMQ connection password

Test cases:

• testSucc: Send message to user.in. Expect enriched message on user.out.
• testRetry: Test AMQ transacted. REST api throws http 500 3x times before sending response. Send message to user.in. Expect enriched message on user.out.

Arquillian-test

Arquillian Cube based test. See README.md in its directory.
