soft-asserts

Soft assertions for Python/Pytest

Installation

    pip install soft-assert

Usage

Assertion is performed immediately after the call check(), but the expected result is obtained only after exit the context manager verify()

Quick example:

    from  soft_assert import check, verify

    def test_something():
        with verify():
            check(1 == 1)
            check(2 > 1, 'Message if test failed')
            check('one' != 'two', 'Some message')

You can use asserts in loop:

    from  soft_assert import check, verify
    
    def test_asserts_in_loop():
        with verify():
            for number in range(1, 10):
                check(number % 2 == 0, '{number} is not a multiple of 2')

Also you can use it with pytest parametrized tests:

    import pytest
    from  soft_assert import check, verify

    @pytest.mark.parametrize('number', list(range(1, 10)))
    def test_pytest_example(number):
        with verify():
            check(number % 2 == 0)

Example of output:

    AssertionError: Failed conditions count: [ 4 ]
    
    1. Failure: Custom message if test failed
    
    2. Failure: Lists not equals
    
    3. Failure: Your custom message; 4 < 5!
    
    4. Failure: one != two
