Test-driven development (TDD) is an approach to program development in which two activities are interleaved throughout the process. Which two activities does TDD interleave?

Architecture design and performance profiling

Requirements analysis and system design

Code review and deployment

Testing and code development

Correct Answer

Testing and code development

Explanation

TDD interleaves testing and code development throughout the development process. You develop code incrementally, along with a set of tests for that increment. You don't start working on the next increment until the code you have developed passes all of its tests.
