Pytest Matcher

The purpose of this library is to simplify asserts containing objects and nested data structures, i.e.:

def test_smth(M):  # A special Matcher fixture
    # ...
    assert result.errors == [
        M(message=M.re("^Smth went wrong:"), extensions=M.dict(code=523)),
        M(message=M.any, tags=M.unordered("one", "two")),
    ]

Here all the structures like lists and dicts are followed as usual both outside and inside a mather object, while the matcher object and other helpers provide their own equality. These could be freely intermixed.
