Pro-Test can generate the test cases that provide all pairwise combinations.
EditByBSEditor: Reduce your software and system testing time by using High Throughput Testing (HTT). Pro-Test can generate the test cases that provide all pairwise combinations.

Pro-Test Features
Software and system testing requirements can explode to an unmanageable number of test cases. As the total number of test cases increases to impractical numbers, you are forced to choose a subset of all possible combinations.

But how do you choose which cases to run and which ones not to? Most people use their gut or intuition to determine the test cases to run. Pro-Test uses High Throughput Testing (HTT) to generate the test cases that guarantee two-way coverage. Pro-Test is simple to use, doesnt require that you use any specific test plan software, and can be used with or without automated test tools. you can free download Pro-Test 1.0 now.
