Clover

For many years Atlassian Clover has provided Java and Groovy developers a reliable source for code coverage analysis. This dependability has allowed us to focus our development efforts on delivering new features and improvements to our core offerings, including Jira Software, Bitbucket, and others. All of this has lead to our decision to open source Clover, what we believe is the best way to give Clover the focus and attention it deserves. Developers are ready and eager to contribute to Clover as they have with our other open-source projects including the IDE connectors and dozens of libraries. Although Clover is already a powerful code coverage tool we’re excited to see what the community will do to make it thrive.

Balance your effort spent on writing applications and test code. Use the most sophisticated code coverage tool for Java and Groovy. OpenClover measures code coverage for Java and Groovy and collects over 20 code metrics. It not only shows you untested areas of your application but also combines coverage and metrics to find the riskiest code. The Test Optimization feature tracks which test cases are related to each class of your application code. Thanks to this OpenClover can run tests relevant to changes made in your application code, significantly reducing test execution time. Do testing getters and setters bring much value? Or machine-generated code? OpenClover outruns other tools in its flexibility to define the scope of coverage measurement. You can exclude packages, files, classes, methods, and even single statements. You can focus on testing important parts of your code. OpenClover not only records test results but also measures individual code coverage for every test.
