如何将 NodeJs 与 Jenkins 集成？

Question

我正在尝试使用 Webdriverio 和 chrome 将测试与 Jenkins 集成。 我遇到的问题是，即使测试在我的本地机器上运行，它们在 Jenkins 上也失败了，收到的错误是： 同样重要的是，这个 jenkins 服务器不在我的本地机器上，我不知道如何在上面安装 chrome。

至于我正在使用的 wdio.conf.js ： browserName: 'chrome', , baseUrl: 'http://localhost', , 服务：['chromedriver']，

> publicrepo@1.0.0 test
> npx wdio run ./wdio.conf.js

我通过在 jenkins（也是一个容器）内创建一个 docker 容器并添加了这些版本的 chrome(google-chrome-stable_91.0.4472.114-1_amd64.deb) 和 chromedriver(chromedriver_86.0.4240.22) 使其工作.bin），有时在容器中也可能存在 node_modules/fibers 问题，解决方案是运行以​​下命令：RUN npm uninstall fiber 运行 npm install fiber@4.0.3（节点版本 14）。

Dockerfile：

WORKDIR /test/test

RUN apt-get update -y && \
    apt-get install -y \
    packagekit-gtk3-module \
    libx11-xcb1 libdbus-glib-1-2 \
    dos2unix

# Download/unpack Firefox
RUN wget https://download-installer.cdn.mozilla.net/pub/firefox/releases/83.0/linux-x86_64/en-US/firefox-83.0.tar.bz2 -q -P /opt && \
    cd /opt && tar xjf firefox-83.0.tar.bz2 && \
    rm -f firefox-83.0.tar.bz2 && \
    ln -s /opt/firefox/firefox /usr/bin/firefox

# Download/unpack GeckoDriver (Selenium driver for Firefox)
RUN wget https://github.com/mozilla/geckodriver/releases/download/v0.28.0/geckodriver-v0.28.0-linux64.tar.gz -q && \
    tar xzf geckodriver-v0.28.0-linux64.tar.gz && \
    rm -f geckodriver-v0.28.0-linux64.tar.gz && \
    chmod +x geckodriver && \
    mv geckodriver /usr/bin/geckodriver

# Install Google Chrome from local .deb file
COPY test/docker/binaries/ .
RUN chmod 755 google-chrome-stable_91.0.4472.114-1_amd64.deb && \
    apt install ./google-chrome-stable_91.0.4472.114-1_amd64.deb -y && \
    rm google-chrome-stable_91.0.4472.114-1_amd64.deb

# Set permissions and move/rename ChromeDriver to somewhere under $PATH
RUN chmod 755 chromedriver_86.0.4240.22.bin && \
    mv chromedriver_86.0.4240.22.bin /usr/bin/chromedriver


RUN apt install default-jre -y
RUN npm install
RUN npm uninstall fibers
RUN npm install fibers@4.0.3```
