Tests

All of our tests are 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 to 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 at which the test would expect something to happen (like deploying a Node.js 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 way to test is locally. All tests are started via make. Make will download and build all the required dependencies.

make tests

This will run all defined tests. If you only want to run a subset of the tests, run make tests-list to see all existing tests and run them individually.

For example, make tests/node will run the Node.js 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 will want to see what is happening inside of Jenkins. Your Jenkins instance can be found here:

http://localhost:8888/ (admin:admin)

Sometimes you just want to create another push webhook without having to wait for the Git repository to be initialized and pushed.

In 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 fully automatic integration test running on TravisCI: https://travis-ci.org/amazeeio/lagoon. It is defined inside the .travis.yml file, and runs automatically for every pull request that is opened.

This will build all images, start an OpenShift and run all tests.

The tests can be found here:
