TDD
n.n. Stands for Test-Driven Development. A way of writing computer code where you write a test for a small feature before you actually write the code for it.
n. Abbreviation for Test-Driven Development. A software development process relying on the repetition of a very short development cycle: requirements are turned into very specific test cases, then the software is improved so that the tests pass.
Our team uses TDD to ensure our code has fewer bugs.
By adopting TDD, the engineering department noticed a significant decrease in regression errors during the final stages of the project.
While TDD can initially slow down the development phase, it often results in a more modular and maintainable codebase that is easier to refactor over time.
Commonly used in technical and software engineering contexts; often functions as an attributive noun in phrases like 'TDD approach' or 'TDD cycle'.
