### Adding New Features

1. Read related source files and tests
2. Write implementation following existing patterns
3. Add comprehensive tests
4. Run `mvn formatter:format license:format test`

#### Adding additional integration tests

Additional integration tests for a certain elasticsearch modules that are specific to certain cluster configuration can be declared in a separate so called `qa` subproject of your module.

- Restart the server.
- Configure an [OAuth service provider](https://docs.wso2.com/display/IS540/Adding+and+Configuring+a+Service+Provider).
