Test Driven Development

Test-driven development (TDD) is a software development technique that uses short development iterations based on pre-written test cases that define desired improvements or new functions. Each iteration produces code necessary to pass that iteration's tests. Lastly, the developer refactors the code to accommodate changes. A key Test-driven development (TDD) concept is that preparing tests before coding facilitates rapid feedback changes.

Sentia believes that Test-driven development is a key component to delivering high quality software will minimal issues. It reduces the Cost of Change for an application and facilitates quality of code and development speed.
