Testability
A fundamental concept that unites the chapters of this book is testability. When code is testable, we have confidence in its architecture and implementation. We can test it thoroughly with ease. Bugs are quickly detected and easily fixed. The first step to improving testability in an application is to establish a natural feedback loop between application code and test code, using signals from testing to improve application code. The energy devoted to writing complex tests for untestable code should be channeled into making the code more testable, allowing simpler tests to be written. With this feedback loop and focus on testability, tests contribute to code quality and application reliability.
Testability is not a binary quality. When ...
