Gollum is an open source wiki software used by GitHub.com, Nature, and others. It uses Selenium WebDriver with JUnit to test its live preview feature, which requires a real browser. To improve testing, Sauce Labs' Cloud was used to run tests in parallel across multiple browsers on different operating systems. The use of parameterization and meaningful test names enabled the tests to be consolidated into one file while maintaining their individuality. Leveraging the hosted cloud option allowed the tests to complete quickly, reducing the time required for testing. The results are reported using tools such as behrica's test watcher and saucerest-java, enabling the tests to run successfully on multiple environments.
