How to rename the test cases of html report generated by PyTest

Question

Below is the HTML report generated by PyTest with Test case name as "test_demo.py::test_demo_framework[0]" instead of this method's name I want to display some actual tests name like "Verify username and password" which ideally describes what kind of test was performed and gives a better understanding to the Report reader, obviously from method name/number, it's hard to identify what was tested as part this Tests.

I want to rename the yellow highlighted Testcases's name.

Answer 1

Use this hookwrapper in conftest:

@pytest.mark.hookwrapper
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

And for each test you run, you will have a specific name. Also you can make it dynamic(using a parameter) - eg:

def test_username(my_username):
 test_username.__doc__ = "Verify username and password for: " + str(my_username)
