Mohit Nayyar’s Summary

Since early 2008, after completing my doctorate in theoretical physics at Penn State University, I've been working as a quality assurance engineer at Wolfram Research Inc. I test various types of data sets which have been incorporated into Mathematica, the software Wolfram Research is best known for, since version 6 (2006), and which form the backbone of wolframalpha.com, the recently launched computational engine.

My primary responsibility is the regression testing of these data sets. To verify the consistency of the data I rely heavily on pattern testing and on statistical tests that look for outliers. Due to similarities in the organization and structures of these data sets, I've been able to automate the process of writing many of these tests. I've also written code that extracts detailed test coverage information from the test files and presents them graphically. Since the wolframalpha.com project began I've also been involved with website testing through a Ruby library called Watir. These tests can simulate a user's interaction with the website and can help detect breakage much faster than manual testing. I have also been writing some shell scripts which control interactions between websites and mathematica for the purposes of testing.
