SaaS - 5.3 - The TDD cycle: red-green-refactor
Introduction
Test Driven Development is an evolutionary approach to software development that requires a developer to write test code before that actual code and then write the minimum code to pass that test. This process is done iteratively to ensure that all units in the application is tested for optimum functionality, individually and in synergy with others. This produces applications of high quality in less time.
TDD vs BDD
Advantages and Disadvantages
Advantages
ensures the code is tested and enables you to retest your code quickly and easily, since it’s automated.
Seams

• Capture that thought in a test, which fails! • Write the simplest possible code that lets the test pass! • Refactor: DRY out commonality w/other tests! • Continue with next thing code should do !
