Dokku test suite

Dokku has a full test suite to assist in quick iterating development. These tests include a linter using shellcheck, functional unit tests using the bats testing framework, and a deployment suite of example apps that use the most popular languages and frameworks.

We maintain the Dokku test harness within the tests directory:

  • tests/unit/*.bats: Bats tests
  • tests/apps/: Example applications that can be used for tests

Continuous Integration

All pull requests have tests run against them on CircleCI, a continuous integration platform that provides Docker support for Ubuntu Trusty 14.04.

If you wish to skip tests for a particular commit - e.g. Documentation changes - you may add the [ci skip] designator to your commit message. Commits that should be tested but have the above designator will not be merged.

While we do provide official packages for a variety of platforms, as our test suite currently runs on Ubuntu Trusty 14.04, we only provide official installation support for that platform.

Local Test Execution

  • Setup Dokku in a vagrant vm
  • Run the following to setup tests and execute them:

    vagrant ssh
    sudo su -
    cd ~/dokku
    make ci-dependencies setup-deploy-tests
    
    # execute the entire test suite (linter, bats tests, and app deployment tests)
    make test
    
    # run linter & update vagrant Dokku install from local git clone
    make lint copyfiles
    
    # execute all bats tests
    make unit-tests
    
    # execute all app deployment tests
    make deploy-tests

Additionally you may run a specific app deployment tests with a target similar to:

make deploy-test-nodejs-express

For a full list of test make targets check out tests.mk in the root of the Dokku repository.
