示例1: tick_classes
# 需要導入模塊: from hypothesis import strategies [as 別名]
# 或者: from hypothesis.strategies import from_type [as 別名]
def tick_classes(request):
"""
Fixture for Tick based datetime offsets available for a time series.
"""
return request.param
# ----------------------------------------------------------------
# Global setup for tests using Hypothesis
# Registering these strategies makes them globally available via st.from_type,
# which is use for offsets in tests/tseries/offsets/test_offsets_properties.py 示例2: test_mean_properties
# 需要導入模塊: from hypothesis import strategies [as 別名]
# 或者: from hypothesis.strategies import from_type [as 別名]
def test_mean_properties(data, type_, strat):
strat = strat or st.from_type(type_)
values = data.draw(st.lists(strat, min_size=1))
result = mean(values) # already testing no exceptions!
# TODO: property assertions, e.g. bounds on result, etc.
if type_ is Fraction:
assert min(values) <= result <= max(values)
# What constraints make sense for an integer mean?
# TODO: metamorphic test assertions. For example, how should result
# change if you add the mean to values? a number above or below result?
# Remove some elements from values? 示例3: everything_except
# 需要導入模塊: from hypothesis import strategies [as 別名]
# 或者: from hypothesis.strategies import from_type [as 別名]
