I am using python v.2.7.1 for my research work in software testing. I have already downloaded the source codes and found the built-in testsuites for running on the build. However, i was wondering if by any chance are there any testsuites which exist that are primarily meant for developers of the source code which can be used before releasing a build, for instance smoke testsuite/regression testsuites, besides the one already distributed with source code.
