How To Contribute

We are happy about everyone who contributes to mammooc! Here is a little guide to simplify contributing:

1. Fork the Repository
2. Implement a new feature or fix a bug (have a look at our Issues)
3. Add tests for your code

• we use rspec for model and controller tests
• for our feature tests we use capybara (with selenium)
• You can find all tests in the spec directory
• To run all tests: bundle exec rspec

4. Create Pull request

• if your request gets two times a +1, we will merge your request

If you want to do a perfect job:

• have a look at our [Code Style Guideline](Code Style Guidelines)
• we use rubocop to automatically correct the code: rake rubocop:run

How you run the application on localhost:

1. please have a look at our environment variables below

• some of them are marked as necessary, these have to be set for running the application

2. we use passenger as application server

• to start the application: passenger start
• the application is available at: localhost:3000
• stop the application: passenger stop

If you want to test out stuff feel free to use our dev deployment (so you don't polute the production data):

• Our dev-branch is deployed under: https://mammooc-dev.herokuapp.com/
• Username: max@example.com or maxi@example.com
• Password: 12345678
• the database will be reset after each deployment
