A pytest plugin that allows multiple failures per test.

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

Note: Requires pytest 6.0 or above.

From PPI:

$ pip install pytest-check

Or from github.

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

Usage

Example using import:

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:

=================================== FAILURES ===================================
_________________________________ test_example _________________________________
FAILURE:
assert 1 > 2
  test_check.py, line 14, in test_example() -> check.greater(a, b)
FAILURE:
assert 2 <= 1
  test_check.py, line 15, in test_example() -> check.less_equal(b, a)
FAILURE: Is 1 in the list
assert 1 in [2, 4, 6]
  test_check.py, line 16, in test_example() -> check.is_in(a, c, "Is 1 in the list")
FAILURE: make sure 2 isn't in list
assert 2 not in [2, 4, 6]
  test_check.py, line 17, in test_example() -> check.is_not_in(b, c, "make sure 2 isn't in list")
------------------------------------------------------------
Failed Checks: 4
=========================== 1 failed in 0.11 seconds ===========================

Example using fixture:

def test_example(check):
    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")

validation functions

  • check.equal - a == b
  • check.not_equal - a != b
  • check.is_ - a is b
  • check.is_not - a is not b
  • check.is_true - bool(x) is True
  • check.is_false - bool(x) is False
  • check.is_none - x is None
  • check.is_not_none - x is not None
  • check.is_in - a in b
  • check.is_not_in - a not in b
  • check.is_instance - isinstance(a, b)
  • check.is_not_instance - not isinstance(a, b)
  • check.almost_equal - a == pytest.approx(b, rel, abs) see at: pytest.approx
  • check.not_almost_equal - a != pytest.approx(b, rel, abs) see at: pytest.approx
  • check.greater - a > b
  • check.greater_equal - a >= b
  • check.less - a < b
  • check.less_equal - a <= b

Defining your own check functions

The @check_func decorator allows you to wrap any test helper that has an assert statement in it to be a non-blocking assert function.

from pytest_check import check_func

@check_func
def is_four(a):
    assert a == 4

def test_all_four():
    is_four(1)
    is_four(2)
    is_four(3)
    is_four(4)

The above will result in:

...
________________________________ test_all_four _________________________________
FAILURE: assert 1 == 4
  test_fail.py, line 8, in test_all_four() -> is_four(1)
FAILURE: assert 2 == 4
  test_fail.py, line 9, in test_all_four() -> is_four(2)
FAILURE: assert 3 == 4
  test_fail.py, line 10, in test_all_four() -> is_four(3)
------------------------------------------------------------
Failed Checks: 3
=========================== 1 failed in 0.12 seconds ===========================

Using check as a context manager

You can use the check() context manager to wrap any assert that you want to continue after in a test.

from pytest_check import check


def test_context_manager():
    with check:
        x = 3
        assert 1 < x < 4

Within any with check:, however, you still won't get past the assert statement, so you will need to use multiple with check: blocks for multiple asserts:

    def test_multiple_failures():
        with check: assert 1 == 0
        with check: assert 1 > 2
        with check: assert 1 < 5 < 4
