System Rules is a collection of JUnit rules for testing code which uses

Development Guide

System Rules is build with Maven. If you want to contribute code than

  • Please write a test for your change.
  • Ensure that you didn't break the build by running
    mvnw test
    .
  • Fork the repo and create a pull request. (See Understanding the GitHub Flow)

The basic coding style is described in the EditorConfig file

.editorconfig
.

System Rules supports Travis CI (Linux) and AppVeyor (Windows) for continuous integration. Your pull request will be automatically build by both CI servers. On Travis CI we build your pull request with OpenJDK 6 and run test with different JDKs (Java 6 to 10).
