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.

  skips: ['*_test.py', 'test_*.py']
>> Issue: Use of assert detected. The enclosed code will be removed when
   compiling to optimised byte code.
