[英]Gitlab CI - Django functional tests - splinter
I want to run some automation tests on github on a project of mine with a Django framework. 我想在github上使用Django框架在我的项目上运行一些自动化测试。 Therefore I am using a Django functional test.
因此我正在使用Django功能测试。 While executing the test on my local pc works fine, my pipeline is always failing with those tests.
虽然在我的本地电脑上执行测试工作正常,我的管道总是失败与这些测试。
I assumed, that chromedriver wasn't working correctly and after some research on the internet, I found out, that I need to install chrome as browser, so I modified my requirements.txt for pip like this: 我假设,chromedriver工作不正常,经过对互联网的一些研究,我发现,我需要安装chrome作为浏览器,所以我修改了我的requirements.txt for pip,如下所示:

# chrome
self.browser_chrome = Browser('chrome', **executable_path)

With this, a chrome browser has been installed, but now I get this error: 有了这个,已经安装了一个chrome浏览器,但是现在我收到了这个错误:
selenium.common.exceptions.WebDriverException:
Message: Service /builds/mitfahrzentrale/mitfahrzentrale/venv/chromedriver unexpectedly exited.
Status code was: 127
What do I need to modify in order to use chromedriver for gitlab? 为了将chromedriver用于gitlab,我需要修改什么?
I don't think the google-chrome
package does what you think it does. 我不认为
google-chrome
软件包可以满足您的需求。 Looking at its source code , it's a Python wrapper for a set of AppleScript commands around the Chrome browser on MacOS and will certainly not install the browser on Linux. 查看其源代码 ,它是MacOS上Chrome浏览器周围的一组AppleScript命令的Python包装器,肯定不会在Linux上安装浏览器。
For reference, here is the (stripped) Gitlab CI pipeline we're using with Django and Selenium to run tests with Firefox and Chrome: 作为参考,这里是我们与Django和Selenium一起使用的(剥离的)Gitlab CI管道,用于在Firefox和Chrome上运行测试:
stages:
- test
.test:
coverage: '/TOTAL.*\s+(\d+%)$/'
test-linux_x86_64:
extends: .test
image: python:3.7.1-stretch
stage: test
tags:
- linux_x86_64
script:
- apt -qq update
- DEBIAN_FRONTEND=noninteractive apt -qq -y install xvfb firefox-esr chromium chromedriver
# download geckodriver as no distro offers a package
- apt install -qq -y jq # I don't want to parse JSON with regexes
- curl -s https://api.github.com/repos/mozilla/geckodriver/releases/latest | jq -r '.assets[].browser_download_url | select(contains("linux64"))' | xargs -n1 curl -sL | tar -xz -C /usr/local/bin
- chmod +x /usr/local/bin/geckodriver
# prepare Django installation
- python -m venv /opt/testing
# bundled pip and setuptools are outdated
- /opt/testing/bin/pip install --quiet --upgrade pip setuptools
- /opt/testing/bin/pip install --quiet -r requirements.txt
- xvfb-run /opt/testing/bin/python manage.py test
Some notes: 一些说明:
xvfb
is used to run the browser in a virtual display; xvfb
用于在虚拟显示器中运行浏览器; the modern browsers are able to run in headless mode (add --headless
to chromedriver options), making the virtual display unnecessary. --headless
控制器选项),使虚拟显示不必要。 If you don't need to support old browser versions, you can omit the xvfb
installation and xvfb-run
usage. xvfb
安装和xvfb-run
用法。 The tests will run as root
in container; 测试将在容器中以
root
身份运行; at first, we got the error 起初,我们得到了错误
E selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally E (unknown error: DevToolsActivePort file doesn't exist) E (The process started from chrome location /usr/bin/chromium is no longer running, so ChromeDriver is assuming that Chrome has crashed.) E (Driver info: chromedriver=2.41,platform=Linux 4.15.10-300.fc27.x86_64 x86_64)
If you face this, you need to pass the additional flag --no-sandbox
to Chrome because it refuses to run as root
without it: 如果你面对这个,你需要将额外的标志
--no-sandbox
传递给Chrome,因为它拒绝以root
身份运行而没有它:
chrome_options = webdriver.ChromeOptions() chrome_options.add_argument('--no-sandbox') ds = DesiredCapabilities.CHROME ds['loggingPrefs'] = {'browser': 'ALL'} driver = webdriver.Chrome(desired_capabilities=ds, options=chrome_options)
