There are numerous competing and complementary theories regarding software testing and development methodologies. Reading up on the world of test methods provides an excellent background for any developer looking to improve the ways in which they construct, implement, and manage tests. For brevity's sake, we will only introduce two paradigms in this book that are particularly useful for Backbone.js testing—Test-Driven Development (TDD) and Behavior-Driven Development (BDD).

Making tests a first-class priority in the development process
Encouraging code to be written in small modular units
Preventing the knowledge of code implementation details from unduly influencing the tests
