The IIT Madras BS Software Testing (Software Testing) End Term paper sat on 28 Apr 2024, in the January 2024 term, set QDB3: 21 questions for 100 marks in 180 minutes. Every question is below with its answer. Take it as a timed mock test to be marked, or read it through first.
What is/are the main disadvantages of Test-Driven Development (TDD)?
Fault isolation is difficult.
The final combined code size may become very large and complex, and it may not be efficient and too cumbersome for (human) readability.
High dependency on test frameworks
A TDD based project is not efficient for pair programming, where writing code and testing can go hand in hand.
Correct answers
The final combined code size may become very large and complex, and it may not be efficient and too cumbersome for (human) readability.
High dependency on test frameworks
