confirm windows support

[jtoy]

all of our dependencies work on windows so this code should work on windows. We want to officially confirm it works. We need someone with a windows machine to run the "cd tests && pytest" to confirm it works on windows. Ideally we would have a test that gets run on every commit to make sure window is working. Unfortunately, travis, our open source testing facility doesn't support windows, can we use another automated test system to make sure windows support works?
