Error running test inside a container

Hi,

I'm running my tests as part of the development pipeline inside a container. When I tried test containers I got the following error:
requests.exceptions.ConnectionError: ('Connection aborted.', FileNotFoundError(2, 'No such file or directory'))

Can someone please help?

Thanks

Hi, have the same issue.

Scenario:

build image from Dockefile below with the following requirements
run the container
copy tests to container
execute pytest command for tests in container

Result: tests fail with errors, with such a log, as below.
Expected result: tests are running normally.
Requirements:

pytest==4.1.1
requests==2.21.0
selene==1.0.0a13
testcontainers==2.3
allure-pytest==2.6.2

Dockerfile:

FROM python:3.6.6-alpine3.7

ADD requirements.txt /app/requirements.txt

WORKDIR /app

VOLUME /var/run/docker.sock:/var/run/docker.sock

RUN pip install --no-cache-dir -r requirements.txt

conftest.py                 10 INFO     browser init
=========================== 26 error in 7.99 seconds ===========================

Code:

from testcontainers.selenium import BrowserWebDriverContainer


def pytest_runtest_setup():
    logging.info('browser init')
    chrome = BrowserWebDriverContainer(DesiredCapabilities.CHROME).start()
    logging.info('browser downloaded')
    with chrome:
        logging.info('get webdriver')
        selene.browser.set_driver(chrome.get_driver())
        logging.info('set webdriver')
        config.timeout = 4
        config.poll_during_waits = 0.05
        config.hold_browser_open = False
        logging.info('browser configured')

What's wrong with the code/configuration?
I couldn't find any information, except add something like
VOLUME /var/run/docker.sock:/var/run/docker.sock to Dockerfile. That didn't help.
Hope that more details will help to figure out the problem.

Best regards, Aleksandr

Hi, i have found guide how to use testcontainers in gitlab-ci.
https://www.testcontainers.org/supported_docker_environment/continuous_integration/gitlab_ci/

and found a problem when i call chrome.get_driver() from the code above

and this continues to spam.

May be this is new trouble for the new issue, but still blocks the same purpose: running test inside a container.

Need a help with understanding what happens here. What these hosts and ports mean?

Best regards, Aleksandr

You should be able to use docker-in-docker given the changes in #66 and #85. Feel free to reopen if problems persist after the next release.

having the same issue as described in the original request
errors like this one and the related ones
urllib3.exceptions.ProtocolError: ('Connection aborted.', FileNotFoundError(2, 'No such file or directory'))

not sure what is the issue as I added all the required things as per this doc: https://www.testcontainers.org/supported_docker_environment/continuous_integration/gitlab_ci/

I ran into this error, not in a CI pipeline but on my laptop. For me the problem was that Docker Desktop wasn't running. After (re)starting Docker Desktop, the error went away.

@ahcub

@ahcub, an example of a working .gitlab-ci.yml can be found here. Does that help?

yep, thanks
