What are the two Flavours of TDD?

There are two levels of TDD:

• Acceptance TDD (ATDD). With ATDD you write a single acceptance test, or behavioral specification depending on your preferred terminology, and then just enough production functionality/code to fulfill that test.
• Developer TDD.

What is the full form of test driven development?

The TDD full form is Test-driven development. The simple concept of TDD is to write and correct the failed tests before writing new code (before development). This helps to avoid duplication of code as we write a small amount of code at a time in order to pass tests.

Can a WebAPI be implemented using DotNet core?

If all things work well, we have successfully implemented a WebAPI using dotnet core following the TDD principle. And always remember these rules of TDD; write implementation of the use cases (test), make sure it fails, then write enough production code to pass only that test, nothing more.
