Python Testing with pytest - Chapter 5 example c AttributeError: 'module' object has no attribute 'config'

Running the examples in chapter 5 c under pytest 5.4.1 causes an AttributeError: ‘module’ object has no attribute ‘config’.

In particular the code:

$ cd /path/to/code/ch5/c/tasks_proj/tests/func
 $ pytest --tb=no test_api_exceptions.py -k TestAdd

causes:



(bopytest) [user@computer func]$ pytest -v test_api_exceptions.py -k TestAdd

From the digging I have done it seems that the capability to do

pytest.config

from

pytest.config.getoption('nice'):

was deprecated in pytest 4.0 and removed from pytest 5.0.

What did work for me was:

def pytest_report_header(config):
    """Thank tester for running tests."""
    if config.getoption("nice"):
        return "Thanks for running the tests."


def pytest_report_teststatus(config, report):
    """Turn failures into opportunities."""
    if report.when == "call":
        if report.failed and config.getoption("nice"):
            return (report.outcome, "O", "OPPORTUNITY for improvement")

Cheers

“nice” workaround, John.
