In the programming arena, developers have to work in the dark, which is very similar to walking in a dark house from room, to room to understand what each room can do, and use that room for a specific purpose.
When developers write the test for code, before developing features for an application, they can improve on the quality and productivity of the software development life cycle; it’s like switching on the lights in the dark room.
In today’s article, we are going to talk about, the Test Driven Development (TDD) methodology, in order to understand how software development is done.
Fear can be managed through, test-driven development, so that a hard problem, can be seen from beginning to end.
Developers are aware of the gap between decision and feedback, which can take place during programming, and can have control of that gap, when they use TDD.
New code is written only if an automated test has failed, in order to eliminate duplication, when test-driven development, is actually the methodology used by developers.
The craft of producing automated tests for production code, is known as test-driven development, which is used to drive the design and programming of the code.
A test is first developed, which specifies and validates, what the code will do, for every bit of functionality of a software developed.
As much code as it is necessary will be produced, in order to pass the test; the refactoring of the code happens once it has been developed, this phase simplify and clarify both production code and test code.
TDD drives or dictates the code, which is developed, in order to provide a specification, of what a piece of code actually does.
Thinking about what the system should do, is what developers should do, before they write code for a software, which they can do when they use the TDD methodology.
What testing does for coding is very important, because it helps developers, to overcome the obstacles which plague software development.
As an iterative software development practice, in TDD, developers define unit tests before the production code is actually finished.
TDD is within agile methodologies, which requires developers to follow three phases, which are: the red phase which forces developers to test first instead of test-last.
During the green phase, developers develop enough code to pass the test, and during the refactoring phase, developers focus on design and quality, through refactoring operations.
As a safety net, a set of regression test cases are used.
Code quality increases when the focus is on testing, and also the confidence of developers’ increases, in their source code.
Although different techniques and approaches are being used nowadays, in order to produce reliable software, the software testing dictates the quality of the software.
Many developers are not concerned with the testing of software, until it’s time for testing, which can affect the software quality.
As an agile practice, TDD has gained popularity, when it was defined as a fundamental part of eXtreme Programming (XP).
The process which relies on the repetition of a very short development cycles, is known as a test-driven development.
TDD is based on the test-first concept of XP, and encourages simple design with high level of confidence on the source code.
