anybox.testing.datetime Description

anybox.testing.datetime is a Python module to allow playing with time in tests.This README is also a doctest. To it and other doctests for this package, simply do:nosetests --with-doctest --doctest-extension=txtBefore anything, the package must be imported in order to replace the regular datetime module with the modified one:>>> import anybox.testing.datetime>>> from datetime import datetime>>> import timeLet's keep the real value of now around:>>> start = datetime.now()>>> start_t = time.time()Then you can:>>> datetime.set_now(datetime(2001, 01, 01, 3, 57, 0))>>> datetime.now()datetime(2001, 1, 1, 3, 57)>>> datetime.today()datetime(2001, 1, 1, 3, 57)The time module goes along:>>> datetime.fromtimestamp(time.time())datetime(2001, 1, 1, 3, 57)Note that you can expect a few microseconds difference (not displayed here because datetime.fromtimestamp ignores them).Don't forget afterwards get back to the regular system clock, otherwise many pieces of code might get very suprised if the system clock looks as if it's frozen:>>> datetime.real_now()Now let's check it worked:>>> now = datetime.now()>>> now > startTrue>>> from datetime import timedelta>>> now - start < timedelta(0, 0, 10000) # 10 msTrueAnd with the time module:>>> now_t = time.time()>>> now_t > start_tTrue>>> now_t - start_t < 0.01 # 10 ms againTrueProduct's homepage
