How to call method on every py.test assertion failure?

I personally haven't used but this might be your solution:https://pytest.org/latest/example/simple.html#writing-well-integrated-assertion-helpers

Also this could help:https://pytest.org/latest/assert.html#advanced-assertion-introspection

You have to use hooks. https://docs.pytest.org/en/latest/example/simple.html#post-process-test-reports-failures

@pytest.hookimpl(hookwrapper=True, tryfirst=True)def pytest_runtest_makereport(item, call):    outcome = yield    rep = outcome.get_result()    setattr(item, "rep_" + rep.when, rep)    return rep@pytest.fixture(autouse=True, scope='session')def driver(platform, request):    """ some driver setup code """    yield driver    if request.node.rep_call.failed:        try:            driver.get_screenshot_as_png()        except:            pass    driver.quit()

And if you want to attach a screenshot to allure report, simply do:

@pytest.fixture(autouse=True, scope='session')def driver(platform, request):    """ some driver setup code """    yield driver    if request.node.rep_call.failed:        # Make the screen-shot if test failed:        try:            allure.attach(                driver.get_screenshot_as_png(),                name=request.function.__name__,                attachment_type=allure.attachment_type.PNG)        except:             """ do something """        driver.quit()

I think that screenShotInSelenium page should give you enough information regarding how you create a screenshot when an assert condition is met.

What you are missing is the use of @AfterMethod
