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 teststests/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:
For a full list of test make targets check out tests.mk in the root of the Dokku repository.
Executing a single test suite
When working on a particular plugin, it may be useful to run only a particular test suite. This can be done by specifying the test suite path:
It is also possible to target multiple test suites at a time.
Executing a single test
In order to increase testing velocity, a wrapper script around bats is available that can be used to run a single testcase within a suite.
Tests within a suite may be listed by specifying the suite as a parameter to the tests/bats-exec-test-single script.
A single test can be specified as a second parameter. The test is selected by fuzzy-match, and only the first match is executed.
Some special characters are translated in the test listing - specifically the characters ( ) : - while others are not. The fuzzy matching happens on the test names listed when no second character is invoked, so executing a test with a more specific name will work as expected.
