pytest: Best Way To Add Long Test Description in the Report

Question

By default pytest use test function names or test files names in pytest reports

is there any Best way to add test description (Long test name) in the report with out renaming the files or functions using pytest?

Can we do this by updating the testcase name at run-time like ?

request.node.name

request.node.name = "Very Very Very Very Very long long long long name name name name"

Description after test-name

def test_ok():
"""Very Very Very Very Very long long long long name name name name"""
    print("ok")

Using the pytest_runtest_makereport hook, the reported name can be adjusted for each test. (Note that hooks must be placed within a plugin, or a conftest.py)

# conftest.py

import pytest

@pytest.hookimpl(hookwrapper=True)
def pytest_runtest_makereport(item, call):
    outcome = yield
    report = outcome.get_result()

    test_fn = item.obj
    docstring = getattr(test_fn, '__doc__')
    if docstring:
        report.nodeid = docstring


# test_it.py

def test_ok():
    """Very Very Very Very Very long long long long name name name name"""
    print("ok")

This will produce output similar to:

tests/test_stuff.py::test_ok 
Very Very Very Very Very long long long long name name name name <- tests/test_stuff.py PASSED [100%]

See "hookwrapper: executing around other hooks" for more info on the outcome = yield and outcome.get_result() business.
