Lagoon testing

Our tests are all written with Ansible and mostly follow this approach:

  1. They create a new git repository
  2. Add and commit some files from a list of files (in tests/files) into this git repository
  3. Push this git repository into a git server (either locally or on Github)
  4. Send a trigger to a trigger service (for example a Webhook to the Webhook Handler which is the same as a real webhook that would be sent)
  5. Starts to monitor the URL that the test would expect something to happen (like deploying a nodejs app that has the git branch as an HTML text)
  6. Compares the result on the URL with the expected result

Lagoon is mostly tested in 3 different ways:

1. Locally

During local development the best and easiest is to test locally. All tests are started via make. Make will download and build all the required dependencies.

make tests

This would run all tests defined. If you like only to run a subset of the tests, run make tests-list to see all tests that exist and run them individually like make tests/node to run the nodejs Docker Images tests

In order to actually see what is happening inside the microservices, we can use make logs:

    make logs

Or only for a specific service:

    make logs service=webhook-handler

Sometimes you would like to see what is happening inside the Jenkins, it can be found here: http://localhost:8888/ (admin:admin)

Sometimes you just would like to create another push webhook, without to wait for the git repository to be initialized and being pushed. For this case there is a small helper script tests/playbooks/helpers/just-push.yaml that will get the current head of the git repository and push a webhook push. It needs to know which git repository and branch you would like to check and push:

    docker-compose -p lagoon exec tests ansible-playbook /ansible/tests/tests/helpers/just-push.yaml -e git_repo_name=node.git -e branch=develop

2. Automated integration testing

In order to test pull requests that are created against Lagoon, we have a full automatic integration test running on TravisCI: https://travis-ci.org/amazeeio/lagoon. It is defined inside the .travis.yml and runs automatically for every pull request that is opened.

This will build all Images, start an OpenShift and run all tests

3. Real World Testing

To make sure that our services also work in the real world (e.g. deployed on OpenShift with real URLs, real git repositories and stuff), we also have tests for this. Currently we only deploy the develop and master branches to a real OpenShift infrastructure.

For these tests we use the exact same Ansible scripts like the local or the automated testing, we just push to an actual Github repository https://github.com/amazeeio-ci-testing and send webhooks to the webhook-handler that are running OpenShift.

The tests are defined in Jenkinsfile.testing-develop and Jenkinsfile.testing-master. They get their testing infrastructure (endpoints, etc.) from a docker-compose.yaml file within the tests folder.

Beside of that it's exactly the same as the automated integration testing.

The tests can be found here: - develop branch: https://lagoon-ci.amazeeio.cloud/job/lagoon-test-develop/ - master branch: https://lagoon-ci.amazeeio.cloud/job/lagoon-test-master/
