Switching branches while running python unit tests

This is more of a general question about safety in testing than a specific code problem. Lets say I have feature branch for my git repository, I always run a suite of unit tests before I merge back into develop or master. But these unit tests often take a while (on the order of an hour). So I generally kick off the test and then change branches in my repository so I can work on coding other things...I'm assuming this is safe because the .pyc files are already created?

If proper CI is not a preferred option for whatever reason and you are OK with some scripting, then you could do a script that would copy a git revision (git export or git new workdir + checkout there ) and execute tests in that location while you keep going further with changes. Worked fine for me with a large java project.

I recommend that you offload test execution to a proper continuous-integration system such as Jenkins or Travis. Switching out the entire source tree in the middle of a test run is bound to cause weird problems.

Also consider that your test suite likely contains both unit tests and integration tests. Unit tests should be fast! A runtime of 0.1 seconds is a slow unit test. Tests that touch the filesystem, communicate with a database, send packets over the network, and so on are integration tests. You might scale those back to running once or twice a day.
