Test driven development proceeds by quickly cycling through the following steps, with each step taking minutes at most, preferably much less. Since each user story will usually require one to two days of work, a very large number of such cycles will be necessary per story.
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 ...
Test automation, mostly using unit testing, is a key feature of extreme programming and agile software development, where it is known as test-driven development (TDD) or test-first development. Unit tests can be written to define the functionality before the code is written.
Originally embodied within House Report No. 97-201 (H.R. 4242) and then later codified by The Tax Reform Act of 1986, 'Qualified Research' generally constitutes private sector or commercially driven development effort intended to yield innovation within a scientific or technological field. However, administrative difficulties coupled with ...
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.

Acceptance testing of an aircraft catapult Six of the primary mirrors of the James Webb Space Telescope being prepared for acceptance testing. In engineering and its various subdisciplines, acceptance testing is a test conducted to determine if the requirements of a specification or contract are met.

Many programming groups are relying more and more on automated testing, especially groups that use test-driven development. There are many frameworks to write tests in, and continuous integration software will run tests automatically every time code is checked into a version control system.
