A graphical representation of the test-driven development lifecycle. The TDD steps vary somewhat by author in count and description, but are generally as follows. These are based on the book Test-Driven Development by Example, [6] and Kent Beck's Canon TDD article. [8] 1. List scenarios for the new feature List the expected variants in the new ...
In test-driven development tests are used to drive the implementation towards fulfilling the requirements. Tester-driven development instead shortcuts the process by removing the determination of requirements and letting the testers (or the QA team) drive what they think the software should be through the testing (or QA) process.

Continuous test-driven development (CTDD) [1] is a software development practice that extends test-driven development (TDD) by means of automatic test execution in the background, sometimes called continuous testing. [2]
A key aspect of specification by example is creating a single source of truth about required changes from all perspectives. When business analysts work on their own documents, software developers maintain their own documentation and testers maintain a separate set of functional tests, software delivery effectiveness is significantly reduced by the need to constantly coordinate and synchronise ...
Acceptance test–driven development (ATDD) is a development methodology based on communication between the business customers, the developers, and the testers. [1] ATDD encompasses many of the same practices as specification by example (SBE), [2] [3] behavior-driven development (BDD), [4] example-driven development (EDD), [5] and support-driven development also called story test–driven ...
One agile practice, test-driven software development (TDD), is a way of unit testing such that unit-level testing is performed while writing the product code. [69] Test code is updated as new features are added and failure conditions are discovered (bugs fixed).
In this field it is a practice of creating and modifying the design of a system as it is developed, rather than purporting to specify the system completely before development starts (as in the waterfall model). Continuous design was popularized by extreme programming. Continuous design also uses test driven development and refactoring.
