It lets you leverage from standard development practices to get more insight into the requirements covered by the code. JFeature works on top of the well known unit testing framework - JUnit, to identify the requirement coverage in the code.

CodePro seamlessly integrates into any Eclipse based Java desktop development environment, adding static code analysis (with nearly 1,000 audit rules), metrics, automated test generation, JUnit test editing, and team collaboration functionality. Extensive security audit rules were recently added to enable developers to automatically detect and address security vulnerabilities as they are writing code, thus closing the opportunities for potential malicious users, and focusing on quality earlier in the software development lifecycle (SDLC). Seamless integration with Eclipse, IBM Rational, JBuilder and MyEclipse.

PMD scans Java source code and looks for potential problems like:
* Possible bugs - empty try/catch/finally/switch statements
* Dead code - unused local variables, parameters and private methods
* Suboptimal code - wasteful String/StringBuffer usage
* Overcomplicated expressions - unnecessary if statements, for loops that could be while loops
* Duplicate code - copied/pasted code means copied/pasted bugs
