How does boundary value analysis benefit test case design?

  • It ensures that only valid inputs are accepted by the system.
  • It focuses on testing values at the boundaries of valid and invalid ranges.
  • It helps identify errors in the middle of data ranges.
  • It is not relevant to test case design.
Boundary value analysis is a software testing technique that focuses on testing values at the boundaries of valid and invalid input ranges. By testing boundary values, testers can uncover errors related to boundary conditions, which are often more likely to cause issues than values within the range. This technique helps improve the effectiveness and efficiency of test case design.
