Integration Tests¶
Integration Tests are implemented with JUnit 4.
Implementation¶
Integration tests are marked with the annotation @Category(IntegrationTests.class).
To add a new integration test, write a JUnit test and annotate the class with the annotation above.
Special Dockerfiles¶
To run integration tests on Jenkins there exists a special Dockerfile, named Dockerfile.mico-core.integrationtests, which runs the integration tests on 3.6-jdk-alpine Docker container. Build the Dockerfile and run the image to test same as Jenkins does. The Dockerfile runs all tests with the annotation above using the follwing command: .. code:: bash
mvn failsafe:integration-test
Requirements¶
ImageBuilderIntegrationTests require credentials to Docker Hub. Provide the credentials base64 encoded as environment variables:
- DOCKERHUB_USERNAME_BASE64
- DOCKERHUB_PASSWORD_BASE64
To encode the username and the password with base64 you could use
echo -n "username" | base64 -w 0
echo -n "password" | base64 -w 0
There are also integration tests which need some Kubernetes credentials.
At the moment we cannot support this within our integration test environment.
So until fixed, integration tests using Kubernetes won’t work.
You can ignore them with adding the @Ignore annotation on class level.
