TDD Basic

Question 1

What Are The Some Clarifications About Tdd?

Answer 1

• TDD is neither about Testing nor about Design.
• TDD does not mean write some of the tests, then build a system that passes the tests.
• TDD does not mean do lots of Testing.

Question 2

What Is Test Driven Development (tdd)?

Answer 2

• designing and developing tests for every small functionality of an application
• Test is developed which specifies and validates what the code will do.

Question 3

What Is The Primary Goal/benefit Of Unit Testing?

Answer 3

• Having solid unit tests allows the developers to refactor without fear. That is, they can much more easily maintain and extend the application.

Question 4

What Are The Benefits Of Tdd?

Answer 4

• Early bug notification
• Better Designed, cleaner and more extensible code
• Confidence to Refactor
• Good for teamwork & Developers since less debugging time and can easily pick up and work on code

Question 5

What Are Some Of The Common Pitfalls Of Tdd/unit Testing?

Answer 5

• Testing using shared resources is difficult

- Type specific values don’t compare well

Question 6

How To Perform Tdd Test?

Answer 6

• Add a test.
• Run all tests and see if any new test fails.
• Write some code.
• Run tests and Refactor code.
• Repeat.

Question 7

What Are The Difference Between Tdd Vs. Traditional Testing?

Answer 7

• TDD ensures that your system actually meets requirements defined for it
• TDD more focus is on production code that verifies whether testing will work properly. In traditional testing, more focus is on test case design.
• TDD, you achieve 100% coverage test. Every single line of code is tested unlike traditional testing.
