Project description

pytest-check

A pytest plugin that allows multiple failures per test.


This pytest plugin was a rewrite and a rename of pytest-expect.

Installation

From PPI:

$ pip install pytest-check

Or from github.

$ pip install git+https://github.com/okken/pytest-check

Usage

For example test case code:

import pytest_check as check


def test_example():
    a = 1
    b = 2
    c = [2, 4, 6]
    check.greater(a, b)
    check.less_equal(b, a)
    check.is_in(a, c, "Is 1 in the list")
    check.is_not_in(b, c, "make sure 2 isn't in list")

Test results:
