Boundary Value Testing

QA Valley performs BV (Boundary Value) testing as a black box QA technique to uncover software defects resulting from the use of transactional data that exist at the extreme boundaries of the valid data domain or dataset.

Boundary Value Testing also called Boundary Value Analysis (BVA) is a test case design technique used to test the behavior of a program when the extreme boundary values are chosen for an input. These values generally include a value just below the minimum value of a range, the minimum value of a range, a value just above the minimum range, the maximum value, and a value just above the maximum value. The objective of choosing these values is to make sure if the program works correctly for the boundary values, then it will work correctly for all values in between.

As BVA is a type of Black Box Testing Technique, the design of software is not known to the tester. So, the test cases are picked up in a very systematic manner by our testing team at QA Valley. BVA is a relatively simple and formal testing technique that can be very powerful to verify the logic of a program especially during input of data. As BVA is based on critical fault assumption during input, it only tests for a single variable at a time. Such a technique is called Worst Case Testing. Our experienced testers design test cases for BVA on both valid and invalid boundary values to find bugs in the input logic in all the programs of the application.

Employing BVA technique for software testing ensures high coverage of test scenarios along with quality testing strategy. Boundary Value Testing is the best approach to reveal any potential user input bugs in the software product. This testing technique is quite easy to use and remember due to the uniformity of identified test cases. The test cases prepared for BVA are also very small. At QA Valley, our testers use intelligent techniques to select the right test cases from a huge test-case pool to ensure all scenarios are covered for Boundary Value Testing.
