Below my class I want to check
class Toto:
me = 0
def good(self):
return "OK"
With my test launch with pytest and pytest-cov plugin
def test_attr_class():
assert Toto.me == 0 # True
assert Toto().good() == "OK"
My pytest script is OK but my coverage not detect the attribut me in Toto
What is wrong ?
Thanks for help

The responses library provides mocks for requests. In my case, it looks typically like this:
import responses
#responses.activate
def test_foo():
# Add mocks for service A
responses.add(responses.POST, 'http://service-A/foo', json={'bar': 'baz'}, status=200)
responses.add(responses.POST, 'http://service-A/abc', json={'de': 'fg'}, status=200)
#responses.activate
def test_another_foo():
# Add mocks for service A
responses.add(responses.POST, 'http://service-A/foo', json={'bar': 'baz'}, status=200)
responses.add(responses.POST, 'http://service-A/abc', json={'de': 'fg'}, status=200)
How can I avoid this code duplication?
I would love to have a mock_service_a fixture or something similar.
Just as you suggest, creating a fixture solves these issues.
import pytest
import responses
import requests
#pytest.fixture(scope="module", autouse=True)
def mocked_responses():
with responses.RequestsMock() as rsps:
rsps.add(
responses.POST, "http://service-a/foo", json={"bar": "baz"}, status=200
)
rsps.add(
responses.POST, "http://service-a/abc", json={"de": "fg"}, status=200
)
yield rsps
def test_foo():
resp = requests.post("http://service-a/foo", json={"bar": "baz"})
assert resp.status_code == 200
def test_another_foo():
resp = requests.post("http://service-a/abc", json={"de": "fg"})
assert resp.status_code == 200
Running it returns:

There are 2 files, the code in the first one is:
import pytest
class TestXdist2():
#pytest.mark.dependency(name="aa")
def test_t1(self):
print("\ntest_1")
assert True
the code in the second file is:
import pytest
import sys, os
sys.path.append(os.getcwd())
from testcases.test_xdist_2 import TestXdist2
class TestXdist1():
def setup_class(self):
self.x = TestXdist2()
#pytest.mark.dependency(depends=["aa"], scope="module")
def test_t2(self):
print("\ntest_t2")
assert 1==1
if __name__ == "__main__":
pytest.main(["-s", "-v", f"{os.path.abspath('testcases')}/test_xdist_1.py"])
when I run the senond file, I thought test case "test_t1" should be ran firstly, then "test_t2" ran secondly, but the result is like this, "test_t2" is skipped, I don'y know why,

This is the expected behavior - pytest-dependency does not order testcases, it only skips testcases if the testcase they depend on is skipped or failed. There exists a PR that would change that, but is not merged
Until that, you can use pytest-order. If you just want the ordering, you can use relative markers. If you also want to skip tests if the test they depend on failed, you can use pytest-dependency as before, but use the pytest-order option --order-dependencies to order the tests additionally.
Disclaimer:
I'm the author of pytest-order (which is a fork of pytest-ordering).
I have the next file with tests
import pytest
from httpx import AsyncClient
import sys
import config
from main import app
#pytest.mark.asyncio
async def test_register():
async with AsyncClient(app=app, base_url="http://test") as ac:
response = await ac.post("/register", )
assert response.status_code == 200
I want to run it like
if __name__ == '__main__':
pytest.run() # Or something alike
How I can do it? I need it to assign name 'main' to this module, because the main module (which import above) has a constraint like: if __name__ == '__main__', so without it tests will not be run indeed.
pytest.main() would run pytest in the current working directory and this would include your file depending on the filename (e.g. if the filename starts with test_). To run pytest on the current file only you can run:
if __name__ == "__main__":
pytest.main([__file__])
Consider this simple example from pytest's docs
# contents of test_module.py with source code and the test
from pathlib import Path
def getssh():
"""Simple function to return expanded homedir ssh path."""
return Path.home() / ".ssh"
def test_getssh(monkeypatch):
# mocked return function to replace Path.home
# always return '/abc'
def mockreturn():
return Path("/abc")
# Application of the monkeypatch to replace Path.home
# with the behavior of mockreturn defined above.
monkeypatch.setattr(Path, "home", mockreturn)
# Calling getssh() will use mockreturn in place of Path.home
# for this test with the monkeypatch.
x = getssh()
assert x == Path("/abc/.ssh")
How does Pytest figure out that the param monkeypatch is the one for monkeypatching?
I have a pytest testing project running selenium tests that has a structure like:
ProjRoot
|
|_Pytest.ini
|_____________TestFolderA
| |
| |_test_folderA_tests1.py
| |_test_folderA_tests2.py
|
|____________TestFolderB
| |
| |_test_folderB_test1.py
| |_test_folderA_tests2.py
|
|
|___________TestHelperModules
| |
| |_VariousTestHelperModules
|
|____________DriversAndTools
|___(contains chromedriver.exe, firefox profile folder etc)
I have a confTest.py file which I currently run in the ProjRoot, which I use as a setup and tear down for establishing the browser session for each test that is run. It runs each test twice. Once for Chrome and once for Firefox. In my tests I just utilise the resulting driver fixture. The conftest file is as below:
#conftest.py
import pytest
import os
import rootdir_ref
from selenium.webdriver.common.keys import Keys
import time
from webdriverwrapper.pytest import *
from webdriverwrapper import Chrome
from webdriverwrapper import DesiredCapabilities
from webdriverwrapper import Firefox
from webdriverwrapper import FirefoxProfile
#when running tests from command line we should be able to pass --url=www..... for a different website, check what order these definitions need to be in
def pytest_addoption(parser):
parser.addoption('--url', default='https://test1.testsite.com.au')
#pytest.fixture(scope='function')
def url(request):
return request.config.option.url
browsers = {
'firefox': Firefox,
'chrome': Chrome,
}
#pytest.fixture(scope='function',
params=browsers.keys())
def browser(request):
if request.param == 'firefox':
firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities['marionette'] = True
firefox_capabilities['handleAlerts'] = True
theRootDir = os.path.dirname(rootdir_ref.__file__)
ffProfilePath = os.path.join(theRootDir, 'DriversAndTools', 'FirefoxSeleniumProfile')
geckoDriverPath = os.path.join(theRootDir, 'DriversAndTools', 'geckodriver.exe')
profile = FirefoxProfile(profile_directory=ffProfilePath)
print (ffProfilePath)
print (geckoDriverPath)
b = browsers[request.param](firefox_profile=profile, capabilities=firefox_capabilities, executable_path=geckoDriverPath)
elif request.param == 'chrome':
desired_cap = DesiredCapabilities.CHROME
desired_cap['chromeOptions'] = {}
desired_cap['chromeOptions']['args'] = ['--disable-plugins', '--disable-extensions']
theRootDir = os.path.dirname(rootdir_ref.__file__)
chromeDriverPath = os.path.join(theRootDir, 'DriversAndTools', 'chromedriver.exe')
b = browsers[request.param](chromeDriverPath)
else:
b = browsers[request.param]()
request.addfinalizer(lambda *args: b.quit())
return b
#pytest.fixture(scope='function')
def driver(browser, url):
driver = browser
driver.maximize_window()
driver.get(url)
return driver
What I’d like to do is have a conftest file in each Test Folder instead of the ProjRoot. But if I take this existing conftest file and put it in each test folder and then run pytest from the project root using
python –m pytest
letting pytest pickup the test directories from pytest.ini (expecting the test folders to run with their respectively contained conftest files) I have issues with the parser.addoption --url already having been added. The end of the error message is:
ClientScripts\conftest.py:19: in pytest_addoption
parser.addoption('--url', default='https://test1.coreplus.com.au/coreplus01')
..\..\..\VirtEnv\VirtEnv\lib\site-packages\_pytest\config.py:521: in addoption
self._anonymous.addoption(*opts, **attrs)
..\..\..\VirtEnv\VirtEnv\lib\site-packages\_pytest\config.py:746: in addoption
raise ValueError("option names %s already added" % conflict)
E ValueError: option names {'--url'} already added
The purpose of the --url addoption is so I can override the defaults in the conftest file at commandline if I want to point them all to a different url at the same time, but otherwise let them default to running to different url's as specified in their conftest files.
I had a similar issue.
Error was gone after removing all cached files and venv.
