Simple pytest plugin to look for regex in Exceptions

Project description

I really missed assertRaisesRegexp in unittest module from pytest, so I wrote this simple plugin.

Usage

# some_module.py
class ExpectedException():
    pass

def function_to_test():
    raise ExpectedException('error message: 1560')
# test_some_module.py
from pytest import raises_regexp
from some_module import function_to_test, ExpectedException

def test_something_to_test():
    with raises_regexp(ExpectedException, r".* 1560"):
        function_to_test()

Installation

$ pip install pytest-raisesregexp

It installs as a pytest entry point, so you can:

from pytest import raises_regexp
