Dokku now 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.
Bats tests can be found here:
Example apps can be found here:
Setup dokku in a vagrant vm
Test setup and execution
$ vagrant ssh $ sudo su - $ cd ~/dokku $ make ci-dependencies setup-deploy-tests $ make test # execute the entire test suite (linter, bats tests, and app deployment tests) $ $ make lint copyfiles # run linter & update vagrant dokku install from local git clone $ make unit-tests # execute all bats tests $ make deploy-tests # execute all app deployment tests
Additionally you may run a specific app deployment tests with a target similar to:
$ make deploy-test-nodejs-express
