Contributing To The Project

I encourage you to contribute to the Docker Flow Swarm Listener project.

The project is developed using Test Driven Development and Continuous Deployment process. Test are divided into unit and integration tests. Every code file has an equivalent with tests (e.g. reconfigure.go and reconfigure_test.go). Ideally, I expect you to write a test that defines that should be developed, run all the unit tests and confirm that the test fails, write just enough code to make the test pass, repeat. If you are new to testing, feel free to create a pull request indicating that tests are missing and I'll help you out.

Once you are finish implementing a new feature or fixing a bug, run the Complete Cycle. You'll find the instructions below.


Fork docker-flow-swarm-listener.
