Identification of parameters is the crux of Hexawise usage. Parameters should be identified based on the projects testing requirements, timelines and acceptable functional coverage.

Linga,

I'll 2nd John's reply, that learning to identify variation (expressed as parameters and parameter values in Hexawise) is the key skill in learning to apply the combinatorial testing technique. There's no one simple answer to how to identify the parameters, but the best place to start that I'm aware of is in the "Identifying Variation" resource in the Hexawise help.

Hopefully that helps. I'm not sure from the wording of your question, but if what you were really after is how to identify parameters that should have 2-way coverage vs. those that should have 3-way coverage, then that's a little different matter. A good resource to start with is this one about "Mixed-strength tests" in Hexawise.

Cheers,
Sean

Hi Linga,

I also recommend for to use mixed-strength interaction.

Depending upon the criticality of the application we may used 2 way or 3 way. But in this case Hexawise will generate more no of test cases in 3 way on random basis. Where as if we used mix way interaction we can make the critical parameter as 3 way , 4 ways etc & the one which is less important we can have 2 way interaction for them.

Vishal,

Great point.

Thanks for taking the time to contribute your practical insights to people in the Hexawise community!

FYI, for anyone unfamiliar with the mixed strength testing capability in Hexawise, please see:
