Pytest covid.

When you do testing to that extent, you're going to find more people, you're going to find more cases. So I said to my people, slow the testing down — please.

The more failures you get, the more tests it will skip.

# pytest.ini
[pytest]
[covid]
enabled = True
fake_news = False

Or if you like Fox News set fake_news = True and test failures will be reported as success.

test failure contamination

For each test failure, 4% of the remaining tests will randomly fail (they get contaminated), and 1% will be skipped. The effect compounds, so a contaminated test, will contaminate more tests and skip even more. Even with fake_news=True, except a failing test will appear to be passing.

Example:

Running 500 test with a 1% change of failing:

tests/test_covid.py ...........F.........s...............F.....s..sF...s....FsF..F.sFFs....sFs...s..F [ 16%]
FFsFFFssFsFss.s..sFFsFssssFFssssFs.sFssssss.sFss.sssss.sss.sss.sFsFssssssssFsssFssssss.sssssFssFsssss [ 36%]

Same while watching Fox News, or if you believe you'll safe in church:

tests/test_covid.py .....................s....ss..........sssssss.s..s......ss.....s...sss.sss...ss.s [ 16%]
