In which the author dives very deep (far deeper than called for) into using Hypothesis to generate data for tests:

Generating data shapes with Hypothesis

I used Hypothesis to generate random data structure schemas, and then generate random data using them. I learned a lot along the way.

I also got to use this Python oddity for real in a test suite:
github.com/coveragepy/coverage

# Make two sets which are equal but iterate differently.
numset1 = set(range(20))
numset2 = set(range(20))
for i in range(0, 20, 2):
numset2.remove(i)
for i in range(0, 20, 2):
numset2.add(i)

def test_scrambled_sets():
assert numset1 == numset2
assert list(numset1) != list(numset2)
