B101: Test for use of assert¶
This plugin test checks for the use of the Python assert
keyword. It was
discovered that some projects used assert to enforce interface constraints.
However, assert is removed with compiling to optimised byte code (python -o
producing *.pyo files). This caused various protections to be removed.
Consider raising a semantically meaningful error or AssertionError
instead.
Please see
https://docs.python.org/3/reference/simple_stmts.html#the-assert-statement for
more info on assert
.
Config Options:
You can configure files that skip this check. This is often useful when you use assert statements in test cases.
assert_used:
skips: ['*_test.py', 'test_*.py']
