Which White-Box testing coverage metric mandates that every decision branch evaluating to both True and False outcomes must be executed?
Option A is correct. Branch Coverage ensures that each decision point (if, while, case statement) evaluates to both True and False outcomes at least once.
Which software testing type re-executes existing test suites after code modifications to confirm that newly added code did not break existing functionality?
Option A is correct. Regression Testing re-tests unmodified software features after bug fixes or enhancements to ensure no regression defects were introduced.
What initial rapid smoke test is performed on a new software build to verify that basic core compilation builds run stably before deep testing?
Option B is correct. Smoke Testing (Build Verification Test) verifies that critical core functions of a software build work at a high level before accepting it for full QA.
Which acceptance testing phase is conducted by real client end-users at their actual live operational deployment environment?
Option A is correct. Alpha Testing is conducted at the developer site in a controlled environment. Beta Testing is conducted by actual end-users at external real-world sites.
Which advanced testing technique intentionally introduces small artificial code mutations into program files to evaluate test suite effectiveness?
Option C is correct. Mutation Testing creates mutated variants (Mutants) of source code to check if existing test cases are effective enough to catch ('kill') the mutants.
