TDD
TDD is a development paradigm that puts writing tests first. You write the test first and then write code to validate. The main purpose of TDD is rapid feedback. You write a test, run it, and it fails. You then write minimal code to pass the test. Once the test passes, you then refactor your code appropriately.
These processes are iteratively repeated. Focusing on writing tests before code implementation allows developers to see the product from the users’ point of view, thus ensuring a working functionality that meets the users’ needs.
TDD enables software developers to come up with units of code base with a single responsibility – allowing code to do just one thing that works properly. However, the traditional approach is to code and then test. The idea of testing a code base at the end of the development process has been proven to be flawed and comes with a high cost of code maintenance.
Most software developers are more agile than test-driven....
