Software Testing Technology & Digital Applications 2 — Questions and Answers
Question 1: Which type of testing verifies that a web application renders correctly across different browsers such as Chrome, Firefox, and Safari?
- Cross-browser testing (Correct answer)
- Regression testing
- Unit testing
- Smoke testing
Correct answer: Cross-browser testing
Cross-browser testing ensures consistent UI behavior and rendering across multiple web browsers.
Question 2: In mobile application testing, what does 'interrupt testing' involve?
- Simulating interruptions like calls or notifications during app use (Correct answer)
- Stopping the test mid-execution to check logs
- Testing the app when the network connection is interrupted
- Forcing the app to crash and observing recovery
Correct answer: Simulating interruptions like calls or notifications during app use
Interrupt testing validates how an app handles real-world interruptions such as incoming calls, SMS, or push notifications.
Question 3: What is the primary purpose of API testing in a digital application?
- To verify that the user interface looks correct
- To validate data exchange, response codes, and logic between services (Correct answer)
- To check database schema integrity
- To measure screen load times
Correct answer: To validate data exchange, response codes, and logic between services
API testing validates the communication layer between services by checking request/response payloads, HTTP status codes, and business logic.
Question 4: Which tool is most commonly used for automating REST API tests?
- Selenium
- Postman (Correct answer)
- JMeter
- Appium
Correct answer: Postman
Postman is widely used to send HTTP requests, inspect responses, and build automated API test collections.
Question 5: A QA engineer wants to test a Progressive Web App (PWA) offline functionality. What aspect should they focus on?
- Color contrast ratios
- Service worker caching and offline data availability (Correct answer)
- Server-side rendering latency
- SSL certificate validity
Correct answer: Service worker caching and offline data availability
PWA offline support relies on service workers to cache assets and data, so testing should verify what content is available without a network connection.
Question 6: When testing a cloud-based SaaS application, which concern is unique compared to testing on-premise software?
- Functional correctness
- Multi-tenancy data isolation (Correct answer)
- Unit test coverage
- Code compilation errors
Correct answer: Multi-tenancy data isolation
SaaS applications serve multiple customers on shared infrastructure, so verifying that one tenant cannot access another's data is critical.
Question 7: What does 'responsive design testing' validate in a web application?
- That the server responds within acceptable time limits
- That the layout adapts correctly to various screen sizes and orientations (Correct answer)
- That API endpoints return correct HTTP status codes
- That form validation messages appear in real time
Correct answer: That the layout adapts correctly to various screen sizes and orientations
Responsive design testing ensures the UI reflows and displays properly on devices ranging from mobile phones to desktop monitors.
