FreezeGun: easy mocking of Python datetimes

Rubyists desiring similar functionality should check out either of the following libs. As far as I can tell they differ only in their pun selection.<p><a href="https://github.com/travisjeffery/timecop" rel="nofollow">https://github.com/travisjeffery/timecop</a><p><a href="https://github.com/bebanjo/delorean" rel="nofollow">https://github.com/bebanjo/delorean</a><p>In the ruby community, disliking someone's choice of science fiction reference is grounds for a rewrite.

nice project. I usually avoid this by making my APIs accept a datetime objects and make the client code create the datetime object.<p>Pure functions make tests simple.

Quick question: why did you need to write FreezeGun?<p>I've always used Mock <a href="http://www.voidspace.org.uk/python/mock/" rel="nofollow">http://www.voidspace.org.uk/python/mock/</a> to patch datetimes and I've never had any problems.<p>You can patch pretty much anything with Mock.

Cool, but unfortunately it breaks if the code your testing does from datetime import datetime :(<p><a href="https://gist.github.com/4261936" rel="nofollow">https://gist.github.com/4261936</a>

What about those of us who prefer the simpler time module (which works mostly in epoch time)? It would be a simple change to extend FreezeGun to cover that module in a similar way, surely?

I don't really have much experience in datetimes I guess. What is this really good for? Can someone provide some use cases where this library might be helpful?<p>Thanks

How well does this handle aware (non-naive) datetimes?
