TestCafe铬测试作为Docker构建的一部分运行

由于某种原因,在我们的CI中,我们需要在docker容器内运行节点测试(包括获取依赖项等)。因此,我试图将UI测试作为docker构建的一部分运行。

这是我的Dockerfile的样子:

FROM testcafe/testcafe:1.3.3

USER root

#some packages needed for some dependencies
RUN apk add --no-cache yarn python make build-base vim curl 

RUN ln -s /opt/testcafe/docker/testcafe-docker.sh /usr/local/bin/testcafe-docker

WORKDIR /usr/src/app

RUN yarn config set registry https://private-npm-registry --global

COPY package*.json ./

RUN yarn

COPY . .

RUN yarn test:ui:ci

# "test:ui:clean": "rm -rf uitests/reports"
# "test:ui:ci-debug": "yarn test:ui:clean; testcafe-docker 'chromium --no-sandbox' uitests/tests -S -s uitests/reports/screenshots --video uitests/reports/videos -r spec,json:uitests/reports/report.json,html:uitests/reports/report.html",
# "test:ui:ci": "start-server-and-test serve http://127.0.0.1:8080 test:ui:ci-debug"

我得到ERROR Unable to establish one or more of the specified browser connections. This can be caused by network issues or remote device failure.

此外,我尝试使用user用户,但是在运行测试之前在reports文件夹内创建uitests文件夹时,它给出了权限错误。

无论是否有--no-sandbox选项,我都尝试过,出现了同样的问题。也尝试过chromium:headless --no-sandbox,但遇到了同样的错误。

有什么建议吗?谢谢。

更新: 还尝试对用户:user(通过使用/tmp文件夹进行报告来避免权限问题),并遇到相同的问题:

最近的“ Chromium”版本不允许您在root用户下运行它们。在运行TestCafe测试之前,将用户从“ root”更改为user。 另外,您需要设置创建新文件夹的权限。 请参阅write in shared volumes docker

中的详细说明
...
USER user
RUN yarn test:ui:ci

这是由于代理。我们使用代理访问互联网。我在docker映像中添加了http_proxyhttps_proxyno_proxy(127.0.0.1)。 docker容器中的浏览器试图通过代理访问testcafe服务器(在同一容器中运行),因为它不使用127.0.0.1/localhost而是172.17.0.2作为容器中的testcafe服务器主机。因此,将172.17.0.2添加到no_proxy即可。
