Which action does TDD not do?

There is no substitute for user acceptance testing. The behavior of your system is not meant to be tested under adverse conditions. It’s a common misconception that you have to write tests for the system before you write your code.

Is TDD necessary?

There are a lot of reasons to follow. When you have a pure logic function that you need to write, it makes sense for TDD to do the job. When the work you need to do has a clearly defined set of expected inputs and outputs, it’s a good signal that you should use the tool to build your tests and code.

What is Red Green refactor in TDD?

Unit tests are only a part of the concept ofTDD. Understanding the problem domain and fulfilling the requirements are some of the things that the software development approach, known as TCD, focuses on.
