Deliver Your Code with Confidence Using Test-driven Development

by Samudra Gupta

Traditional software development methodologies incorporate a fairly long life cycle in coding, testing, and deployment. But test-driven development (TDD) is a new software development process that turns the traditional processes around by promoting writing tests before writing the functional code. This article examines what test-driven development is all about and explores how to effectively use it within a project.

What Is Test-driven Development?

Conditions for Successful TDD

• You must refuse to write code without a test in place.
• You write your own tests as opposed to any third party. Otherwise, the process will take so much longer that its time-scale could be compromised.
• The internal application design should be highly decoupled so that each module can be tested in isolation.
• Last but not the least, you'll need a mature unit testing framework in place.
