Moving to Test-Driven Development and Exploring Language Paradigms

  • submit to reddit

Michael Feathers defines legacy code as "code without tests."  There's a major qualitative difference when working on code without tests.  Feathers' job is to move software teams from their current process to a test-driven development process.  In this interview he also discusses functional programming and other important paradigms that developers should consider.

 Michael Feathers is a senior consultant at Object Mentor.  He travels around the world working with software teams to help solve their biggest problems.  Seeing the challenges of many software teams instead of just one gives Feathers a unique and broad perspective of the software industry.  His projects involve agile transitions and dealing with large, untested codebases.
