How to get test name and test result during run time in pytest

Question

I want to get the test name and test result during runtime.

I have setup and tearDown methods in my script. In setup, I need to get the test name, and in tearDown I need to get the test result and test execution time.

Is there a way I can do this?

Answer 1

You can, using a hook.

I have these files in my test directory:

./rest/
├── conftest.py
├── __init__.py
└── test_rest_author.py

In test_rest_author.py I have three functions, startup, teardown and test_tc15, but I only want to show the result and name for test_tc15.

Create a conftest.py file if you don't have one yet and add this:

import pytest
from _pytest.runner import runtestprotocol

def pytest_runtest_protocol(item, nextitem):
    reports = runtestprotocol(item, nextitem=nextitem)
    for report in reports:
        if report.when == 'call':
            print '\n%s --- %s' % (item.name, report.outcome)
    return True

The hook pytest_runtest_protocol implements the runtest_setup/call/teardown protocol for the given test item, including capturing exceptions and calling reporting hooks. It is called when any test finishes (like startup or teardown or your test).

If you run your script you can see the result and name of the test:

$ py.test ./rest/test_rest_author.py
====== test session starts ======
/test_rest_author.py::TestREST::test_tc15 PASSED
test_tc15 --- passed
======== 1 passed in 1.47 seconds =======
