Automated software testing for cross-platform systems

Abstract: SILK is the preferred audio codec to use in a call between Skype clients. Everytime the source code has been changed there is a risk the code is no longer bit-exact between all the dffierent platforms. The main task for this thesis is to make it possible to test bit-exactness between platforms automatically to save resources for the company. During this thesis a literature study about software testing has been carried out to find a good way of testing bit-exactness between different platforms. The advantages and disadvantages with the different testing techniques was examined during this study. The result of the thesis is a framework for testing bit-exactness between several different platforms. Based on the conclusions from the literature study the framework is using a technique called data-driven testing to carry out the bit-exactness tests on SILK.
