Question

我正在尝试使用Protractor + SauceLabs在Docker容器中进行自动端到端测试，并且收到错误消息：找不到update-config.json。运行＆＃39; webdriver-manager更新＆＃39;下载二进制文件。＆＃39;我现在正在运行＆＃39; webdriver-manager更新--standalone false＆＃39;在运行端到端测试之前（独立，因为我不需要独立版本，这也需要java）。有趣的是，（可以在下面的命令行输出中看到）该命令有效并且我实际上可以找到update-config.json文件，但是我仍然得到相同的错误。这可能只是量角器的错误，但我想首先检查Stack Overflow。任何帮助将不胜感激，谢谢！

哦，当然测试工作在本地，即使我删除了nodemodules，运行npm install，npm运行e2e sauce，或清除它们，执行npm install，npm运行webdriver-update，npm运行e2e-sauce。< / p>

相关依赖项＆＃34; @ angular / cli＆＃34;：＆＃34; 1.6.6＆＃34;，＆＃34;节点＆＃34;：＆＃34; 8.10.0＆＃34;，＆＃34; npm＆＃34;：＆＃34; 5.6.0＆＃34;，＆＃34;量角器＆＃34;：＆＃34; 5.1.2＆＃34;，＆＃34; ts-node＆＃34;：＆＃34; 4.1.0＆＃34;，

package.json命令：

"e2e-sauce": "ng e2e --port 8100 --env test --sauce",
"webdriver-update": "webdriver-manager update --standalone false --gecko false",

我正在运行的bash脚本：

# for testing purposes, normally environment variable
GIT_COMMIT=aTestCommit;

if [[ -z $GIT_COMMIT ]]; then
  echo "\$GIT_COMMIT environment variable is required!";
  exit 1;
fi

function cleanup {
  docker rm -f $GIT_COMMIT
}

trap cleanup EXIT INT TERM

COMMAND=""
COMMAND+="npm run webdriver-update"
COMMAND+=" && ls ./node_modules/protractor/node_modules/webdriver-manager/selenium"
COMMAND+=" && ng e2e --port 8100 --env test --sauce"

set -ex

docker-compose create --build builder

docker-compose run --name $GIT_COMMIT builder bash -c "$COMMAND"

DockerFile：

FROM node:8

  wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add - && \
  echo "deb http://dl.google.com/linux/chrome/deb/ stable main" > /etc/apt/sources.list.d/google.list && \

运行我的bash脚本时的命令行输出：

Answer 1

根本原因是角度cli ng e2e将默认执行webdriver-manager update。

您使用全局角度cli而非项目本地角色，因此它会尝试使用全局webdriver-manager执行更新，但您没有安装全局webdriver-manager，因此ng e2e报告Error: No update-config.json found。

解决问题的两个选项：

选项1 ：添加webdriver-manager update

，禁用ng e2e --wu false

COMMAND+=" && ng e2e --port 8100 --env test --sauce --wu false"

但是你需要自己更新webdriver，就像你到目前为止一样。

Option2 ：通过删除-g选项

将angular cli安装为项目本地包，而不是全局包

# Install the Angular CLI globally
RUN npm install @angular/cli@1.6.6

Answer 2

发现这是因为我没有使用独立版本的selenium（我不应该使用'--standalone false'）。删除该行并在我的Dockerfile中安装java后，它就像一个梦想。

＆＃39;错误：找不到update-config.json＆＃39;使用Docker，Protractor和SauceLabs
