Questions and Answers

What is the main purpose of sanity testing?

  • To test specific areas affected by bug fixes or new code (correct)
  • To expose faults in the interaction between integrated units
  • To ensure every single unit in the software works correctly
  • To validate the responsiveness of core screens

    • When conducting user interface testing, what should be validated?

  • Interfacing errors among integrated units
  • Timing problems in real-time systems
  • Functionality of key features like push notifications
  • Responsiveness of core screens (correct)

    • What distinguishes integration testing from unit testing?

  • Unit tests are done before any changes are made to the code
  • Unit tests focus on broader context like external APIs
  • Integration testing requires a deployment step while unit testing does not (correct)
  • Integration testing detects faults in individual units
