Boundary Value Analysis

What is Boundary Value Analysis?

Boundary Value Analysis is a technique used in software testing to check for errors at the boundaries of input ranges. It focuses on testing the minimum and maximum values of input variables.

Purpose of Boundary Value Analysis

The main purpose of Boundary Value Analysis is to identify potential errors or bugs that may occur at the edges of acceptable input ranges. By testing these boundaries, testers aim to ensure the reliability and robustness of the software.

How Does it Work?

In Boundary Value Analysis, testers select test cases that include inputs at the lower, upper, and just beyond the boundaries of valid ranges. This helps in uncovering issues that might arise due to boundary conditions.

Benefits

Boundary Value Analysis helps in detecting defects early in the testing phase, which reduces the likelihood of critical issues in production. It enhances test coverage by focusing on critical points where errors are more likely to occur.

Conclusion

Boundary Value Analysis is a valuable testing technique that improves software quality by addressing boundary-related errors effectively. It contributes to delivering more stable and dependable software products to users.
