Boundary value testing is a software testing technique that focuses on testing the boundaries or limits of input values. It involves selecting test cases that lie on or near the boundaries of valid and invalid input ranges. The purpose of boundary value testing is to identify any errors or defects that may occur at the boundaries of the input domain.
Boundary value testing is important for several reasons. Firstly, it helps to uncover errors that are often found at the extremes of input ranges. These errors are more likely to occur due to programming mistakes or incorrect handling of boundary conditions. By testing the boundaries, we can identify and fix these errors before they cause any issues in the software.
Secondly, boundary value testing helps to ensure that the software behaves correctly when it encounters boundary conditions. Boundary conditions are often critical points where the software may behave differently or produce unexpected results. By testing these conditions, we can verify that the software handles them correctly and produces the expected output.
Furthermore, boundary value testing helps to improve the overall quality of the software by providing a more thorough testing approach. It allows testers to focus on critical areas where errors are more likely to occur, rather than testing every possible input value. This saves time and resources while still providing effective test coverage.
In conclusion, boundary value testing is an important testing technique that helps to identify errors at the boundaries of input ranges, ensures correct handling of boundary conditions, and improves the overall quality of the software.
