What is TDD and how can you apply it?

TDD framework instructs developers to write new code only if an automated test has failed. This avoids duplication of code. 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).

What are the 5 steps of TDD?

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 are the different levels of TDD?

There are two levels of TDD Acceptance TDD (ATDD): With ATDD you write a single acceptance test. This test fulfills the requirement of the specification or satisfies the behavior of the system. Developer TDD: With Developer TDD you write single developer test i.e. unit test and then just enough production code to fulfill that test.
