How Testability Driven Development Can Improve the Quality of Your Software

Testability-Driven Development (TsDD) is a software development process that focuses on making code testable first, before writing any production code. This is in contrast to traditional development processes, where code is written first and then tested later.


TsDD is based on the idea that the more testable a piece of code is, the easier it is to find and fix bugs. This is because testable code is easier to understand and reason about.

There are a number of techniques that can be used to make code more testable, such as
