AllPairs, A Test Case Generation Tool

The last couple of days, I have been fervently testing attributes that have multiple values, and I have ended up with enormous grids trying to cover every possible combination with the optimism that no webby corners have been overlooked. And all at once, I saw a light, a host of golden solutions ! Ok, flowery language (pun intended) apart, Rajeshvaran directed me to this neat little tool called AllPairs. So now, this tool is based on the Orthoganal Array Testing Principle and works out the minimum number of pairs for you, so that all conditions may be satisfied. I used it to reduce 43 test cases to 8 and still felt good that the testing had achieved satisfactory coverage. This page from James Bach lists two more tools for test data generation!
