Predictive Testing Information
Can any one throw some light on Predictive Testing, as to what it is, how it is done and where it is applicable? And what are the tools that could be used for doing the same?
Re: Predictive Testing Information
I am not sure if I will answer your question because "predictive testing" can mean different things to different people. I have done "predictive" elements to testing, such as test case estimation or test effort estimation. The former estimates (predicts) the number of test cases that will be needed and the latter estimates (predicts) the cost and resources for the testing effort as a whole.
Beyond that I have done things like failure-intensity estimation/prediction, which is more looking at the nature of the failures you are expecting to find during a given test cycle. I have also done hidden-fault analysis which is predicated upon the notion of attempting to estimate (predict) how many potential faults exist within a given module (or a given system) such that you can estimate how much testing to devote to that area as opposed to others.
So I am not sure if all of that matches what you mean by "predictive testing". As far as tools, there are some tools that might help me do some of what I mentioned but normally I use reliability growth models, queuing models, confidence intervals, and sensitivity analysis to get my numbers and I formalize that in the form of simple spreadsheets.
