The IIT Madras BS Software Testing (Software Testing) End Term paper sat on 13 Apr 2025, in the January 2025 term: 22 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.
A user fills out a web form and clicks the “Submit” button. This action causes the application to transition from the form page to another page (e.g., a confirmation or result page). In the context of an Application Transition Graph (ATG), what type of transition does this represent?
Simple Link Transition
Operational Transition
Form Link Transition
Redirect Transition
Correct answer
Form Link Transition
An online booking system requires users to provide a “check-in date” and a “check-out date” while reserving a hotel room. A tester alters the “check-out date” in the form submission to a date earlier than the “check-in date” to check if the application properly enforces the relationship between the two fields. What type of testing does this scenario describe?
Control flow level bypass testing
Parameter level bypass testing
Value level bypass testing
User session data based testing
Correct answer
Parameter level bypass testing
Which type of testing is performed by suddenly increasing the number of users to a very large amount in order to measure the system’s performance and determine if it can sustain the workload?
Spike testing
Endurance (soak) testing
Compatibility testing
Regulatory testing
Correct answer
Spike testing
Which of the following metrics is categorized as a Maintenance Quality Metric?
Defect Density
Backlog Management Index (BMI)
Code Coverage
Cyclomatic Complexity
Correct answer
Backlog Management Index (BMI)
Consider the following method: double root(int a, int b, int c).
Identify the type of the mutation operator.
Scalar variable replacement
Unary operator insertion
Arithmetic operator replacement
Absolute value insertion
Correct answer
Scalar variable replacement
Why is Test-Driven Development (TDD) ideal for pair programming?
Because it eliminates the need for collaboration between developers.
Because it allows one developer to write code and the other to test.
Because it requires no test frameworks.
Because TDD does not involve testing during development.
Correct answer
Because it allows one developer to write code and the other to test.
In a ride-sharing application, the User Module sends a ride request to the Driver Module via a central messaging service. The modules communicate using message queues. What type of coupling is used in this scenario?
Parameter coupling
Shared data coupling
External device coupling
Message-passing interfaces
Correct answer
Message-passing interfaces
Correct answer
