Which Black-Box testing technique focuses testing efforts directly on the minimum, maximum, and boundary values of input partitions?
Option A is correct. Boundary Value Analysis tests values at and around the boundaries of input partitions (e.g., min-1, min, min+1, max-1, max, max+1).
If an input condition specifies a range from 1 to 100, which test inputs demonstrate complete 2-point Boundary Value Analysis?
Option A is correct. For range [1, 100], 2-point BVA tests boundary points (1, 100) and immediate invalid boundary points outside (0, 101).
Which testing type re-executes previously passed test cases to ensure that recent code modifications have not introduced unexpected side-effect defects?
Option C is correct. Regression Testing verifies that software updates, bug fixes, or enhancements have not disrupted existing features or system stability.
Which initial testing phase evaluates a new software build to confirm that critical core functions work before conducting exhaustive testing?
Option D is correct. Smoke Testing (Build Verification Testing) quickly checks key functional paths to determine if a new software build is stable enough for deeper testing.
What is the key operational distinction between Alpha Testing and Beta Testing?
Option B is correct. Alpha testing is internal testing performed by employees at the developer's site. Beta testing is performed by actual end-users in real operating environments.
