NPTEL Software Testing Assignment

This course will cover various techniques for test case design, as used for testing of software artifacts including requirements, design and code. We will discuss algorithms and techniques for test case design based on graphs, logic, syntax of programming languages and on inputs. Special techniques for testing object-oriented features and web applications will also be discussed. The course will end with symbolic testing techniques. These broadly will cover test cases for both white-box and black-box.
INTENDED AUDIENCE: Any Interested Learners
PRE-REQUISITES: Programming, Algorithms, Discrete Mathematics (basics)
INDUSTRY SUPPORT: The material of this course has been used to offer training for Samsung, ABB and Mindtree. The course will be useful for any firm that does tests their software.

Next Week Assignment Answers


This course can have Associate in Nursing unproctored programming communication conjointly excluding the Proctored communication, please check announcement section for date and time. The programming communication can have a weightage of twenty fifth towards the ultimate score.

Final score = Assignment score + Unproctored programming exam score + Proctored Exam score
  • Assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
  • ( All assignments in a particular week will be counted towards final scoring – quizzes and programming assignments). 
  • Unproctored programming exam score = 25% of the average scores obtained as part of Unproctored programming exam – out of 100
  • Proctored Exam score =50% of the proctored certification exam score out of 100
If any one of the 3 criteria is not met, you will not be eligible for the certificate even if the Final score >= 40/100.

1. Which of the following best defines an infeasible test path?

a. An infeasible test path is one that does not exist in the graph.
b. An infeasible test path is one that can be executed by a failed test case.
c. An infeasible test path is one that cannot be executed by any test case.
d. An infeasible test path is one that does not start at an initial vertex or end at a final vertex.

Answer:- b

2. How are test requirements defined and met in graphs–based structural coverage criteria?

a. Test requirements are basically the same as test paths, they are given as test paths.
b. Test requirements are defined as properties of test paths and they are met by using test paths that satisfy each test requirement.
