## Making your change

### Code change guidelines

All code contributions should contain the following:

* Create unit tests using [Spock](https://spockframework.org/spock/docs/2.0/index.html) for new classes or methods that you introduce.
* Create integration tests that exercise a Gradle build for the bug/feature.
