1. ## Orthogonal Array Testing

Hi All,

Can anyone explain about the Orthogonal Array Testing technique. And how can we use in our functional testing.

Regards,

If you search for Orthogonal Array using the Google Search tool at the top-right of the page, you'll find that this has been asked and answered many times.

And you'll find lots of handy explanations.

Ya that i did before posting in forum.

I need any documents which give fair amount of idea like basic thing so that i can understand and go indepth to implement the same in my testing cycles.?

Regards,

Here is an article I wrote "Orthogonally Speaking" which is pretty basic but I think gets the idea across:
http://www.scribd.com/doc/2175340/Orthogonally
or http://www.combinatorialtesting.com/...ntroductions-1 etc.

I wouldn't spend much time on orthgonal arrays in software testing. A better approach to configuration matrices or to interdependent input testing is coverage arrays (e.g. often overly simplifed as pairwise).

I also wrote a series of posts on advanced combinatorial testing practices and you can find them at http://www.testingmentor.com/imtesty...orial+testing.

Hey thanks Guys. Its a great help i ll try to implement this.

Just to add to all the links, I would like to say OATS is useful in cross browser, OS etc testing only, wherein you need to filter out scenarios that hold relevance to being browser or OS or any other combinations therein dependency.

9. For Orthogonal array implementation from QA angle , see http://www.qafriend.com/test_design_...thogonal_array

10. Orthogonal array testing is a methodical and factual method for a discovery testing system utilized when number of inputs to the application under test is little however excessively complex for a thorough testing.

Orthogonal Array Testing Characteristics:

OAT, is an orderly and measurable way to deal with pairwise connections.

Executing an all around characterized and an exact test is prone to reveal a large portion of the imperfections.

100% Orthogonal Array Testing infers 100% pairwise testing.
