Event details
Working Effectively with Legacy Code
Test Driven Development and Refactoring are powerful tools. With them you can add new code
to systems and make existing code more maintainable. However, refactoring code without
having tests in place can be hazardous. This class presents a collection of dependency
breaking and test writing techniques that can be used to get existing code safely under test for
refactoring. These techniques can be used in conjunction with Test Driven Development to
breathe new life into large existing code bases. This class is structured as a set of lectures,
discussions, and handson exercises.
