Legacy code is code you are responsible for but did not write. It is usually large, usually old, and usually documented by whoever left last. The right tools make everything easier. Here is what makes Understand an effective legacy code analysis tool:
Four things to do with a codebase you have just become responsible for.
Writing tests is key to maintaining legacy code. Understand runs automated tests to ensure your new code is compatible with the intended behavior of the legacy code.
Lack of documentation is one reason understanding legacy code is so challenging. Use Understand to overcome this obstacle by tagging and annotating your code. This feature ensures continuity between you and other engineers working on the same legacy code.
Understand's bottom-up architecture structures legacy code in a way that helps you understand it — built from what the code actually does rather than from a diagram somebody drew years ago.
Understand's CodeCheck feature provides comprehensive coverage of your legacy code, so you know exactly what's working and what's not. Check for mistakes, identify bugs, and resolve errors using this feature for legacy code analysis.
Our free trial enables all features that can be used on a sample code base — or point it at the legacy project you just inherited.
