It's nice to work on Green Fields projects. But most of us aren't that lucky! Most organisations have large legacy code bases to maintain. And the legacy applications, ugly as they are, are often what generates the revenue! But legacy code bases are not easy to work with. Adding new features, or even fixing bugs, is slow and fraught with danger. Unexpected regressions are commonplace. Long testing cycles is the norm. In this talk we will look at some strategies that can enable you to add new features to legacy systems faster and more reliably. We will examine where the hold-ups typically are, and what We will learn how to write cost-effective automated regression tests suites, and how to use unit testing as a way to document your legacy code base for future work, and improve its quality along the way!
