Pair-wise testing applied with online registration

Pair-wise testing is a software testing technique used for design of test cases to test every possibility input parameters pairing interaction together. This result is to decrease in the number of test cases. This paper presents to reduce the number of test cases with pair-wise testing using the reference with algorithm invented and accepted in software testing. It is applied to case in the online registration website (Thai language) to generate test suits in every possible of input parameters. Reducing the number of input parameters is to decrease time consumption of testing and it helps to find highest defects with coverage in testing. The result from the software testing with pair-wise has more effectiveness than the all pair testing up to 60-80%. The reason is to use pair-wise testing in test because society of tester in Thailand has a little to use such method to reduce input parameters before testing. Therefore, it will make a high cost of each testing. However, pair-wise testing in the testing process has an importance for Software Development Life Cycle (SDLC) and Software Testing Life Cycle (STLC) in Thailand.
