Remove FAILURES from pytest output

Question

Pytest is new to me. We try to verify that we have all expected files in a project.

I like every part of the pytest output except for the detailed FAILURES that will confuse our non-programmers.

How can we suppress the FAILURES output?

Current code:

import os.path
import pytest

spec = {"expected_files": ["Dockerfile", "Duckerfile", "Daskerfile"]}

@pytest.mark.parametrize("expected_file", spec['expected_files'])
def test_expected_file_is_in_project(expected_file):
    assert os.path.isfile(expected_file), "File \""+expected_file+"\" not found in project"

Output after running the "pytest -v" command

Answer 1

You may run pytest with the traceback (tb) option set to no in order to suppress the traceback reporting, i.e.:

pytest --tb=no

Check out the Modifying Python traceback printing section of the pytest documentation.
