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. The use
|
||
|
|
of assert is also considered as general bad practice in OpenStack codebases.
|
||
|
|
|
||
|
|
Please see
|
||
|
|
https://docs.python.org/2/reference/simple_stmts.html#the-assert-statement for
|
||
|
|
more info on ``assert``
|
||
|
|
|
||
|
|
:Example:
|
||
|
|
|
||
|
|
.. code-block:: none
|
||
|
|
|
||
|
|
>> Issue: Use of assert detected. The enclosed code will be removed when
|
||
|
|
compiling to optimised byte code.
|
||
|
|
Severity: Low Confidence: High
|
||
|
|
