在黄瓜Ruby中使用Selenium ChromeDriver在W3C模式下(Selenium :: WebDriver :: Error :: UnknownCommandError)无法调用非W3C标准命令 [英] Cannot call non W3C standard command while in W3C mode (Selenium::WebDriver::Error::UnknownCommandError) with Selenium ChromeDriver in Cucumber Ruby

问题描述

我们有Cucumber Ruby自动化框架，我们在Jenkins的Docker上的Chrome无头浏览器上运行了一些测试.几天前，我们这次使用ChromeDriver 2.46和google-chrome-unstable浏览器，并使用以下命令，收到了错误消息:此版本的ChromeDriver仅支持Chrome版本75".

We have Cucumber Ruby automation framework where we run few tests on Chrome headless browser in a Docker on Jenkins. A few days ago we started receiving an error "This version of ChromeDriver only supports Chrome version 75" this time we were using ChromeDriver 2.46 and with google-chrome-unstable browser using the following command:

#Chrome
RUN wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -
RUN echo "deb http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list
RUN apt-get update -y
RUN apt-get install -y google-chrome-unstable
RUN apt-get install unzip

# Set up Chromedriver Environment variables
ENV CHROMEDRIVER_VERSION 2.46
ENV CHROMEDRIVER_VERSION 75.0.3770.8
ENV CHROMEDRIVER_DIR /chromedriver
RUN mkdir $CHROMEDRIVER_DIR
# Download and install Chromedriver
RUN wget -q --continue -P $CHROMEDRIVER_DIR "http://chromedriver.storage.googleapis.com/$CHROMEDRIVER_VERSION/chromedriver_linux64.zip"
RUN unzip $CHROMEDRIVER_DIR/chromedriver* -d $CHROMEDRIVER_DIR
ENV PATH $CHROMEDRIVER_DIR:$PATH

我现在将chromedriver版本更新为75.0.3770.8，将浏览器更新为google-chrome-beta=75.0.3770.27-1

I have now updated chromedriver version to 75.0.3770.8 and browser to google-chrome-beta=75.0.3770.27-1

#Chrome
RUN wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -
RUN echo "deb http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list
RUN apt-get update -y
RUN apt-get install -y google-chrome-beta=75.0.3770.27-1
RUN apt-get install unzip

# Set up Chromedriver Environment variables
ENV CHROMEDRIVER_VERSION 75.0.3770.8
ENV CHROMEDRIVER_DIR /chromedriver
RUN mkdir $CHROMEDRIVER_DIR
RUN echo $CHROMEDRIVER_DIR
# Download and install Chromedriver
RUN wget -q --continue -P $CHROMEDRIVER_DIR "http://chromedriver.storage.googleapis.com/$CHROMEDRIVER_VERSION/chromedriver_linux64.zip"
RUN unzip $CHROMEDRIVER_DIR/chromedriver* -d $CHROMEDRIVER_DIR
ENV PATH $CHROMEDRIVER_DIR:$PATH

现在我可以看到以下错误:

And now I can see the error as:

unknown command: Cannot call non W3C standard command while in W3C mode (Selenium::WebDriver::Error::UnknownCommandError)

unknown command: Cannot call non W3C standard command while in W3C mode (Selenium::WebDriver::Error::UnknownCommandError)

是否可以禁用W3C模式或下载不使用它的旧版Chrome浏览器和驱动程序?我认为禁用W3C检查的可能性很大.

Is it possible to disable W3C mode or download an older version of Chrome browser and driver that doesn't use it? I think the possibility to disable W3C check would be great.

推荐答案

您要做的就是在初始化Webdriver时禁用W3C

All you have to do is just to disable the W3C when initializing the webdriver

options = webdriver.ChromeOptions()
options.add_experimental_option('w3c', False)
create_webdriver('Chrome', options=options)

环境:

• Chrome 75
• ChromeDriver 75
