Developing Applications and Automating Workflows Using Cisco Platforms (DEVASC) — Question 50

What is the first development task in test-driven development?

Answer options

• A. Write code that implements a desired function.
• B. Write a failing test case for a desired function.
• C. Reverse engineer the code for a desired function.
• D. Write a passing test case for existing code.

Correct answer: B

Explanation

The correct answer is B, as test-driven development starts with writing a failing test case to define the desired functionality before any code is written. Options A, C, and D do not reflect the principles of test-driven development, which emphasizes the creation of tests before the implementation of the code.
