E/runner-无法启动WebDriver会话

Question

我创建了一个docker-compose.yml文件来运行一些存储在公共repo中的量角器测试。yml文件中创建了几个容器：

• shared_repo:在其中克隆测试
• 硒集线器：带有硒图像的容器
• chrome：带有selenium/nodechrome调试的容器
• 量角器：带节点的容器：12.14图像

Docker组成文件为：

version: '2.4'
services:
shared_repo:
image: library/postgres:13.2-alpine
container_name: shared_repo
command: bash -c "apk add git && sleep 5s && git clone -b main https://github.com/AlfredoBazo/opwDocker.git && mv /opwDocker /shared_repository && echo "TEST" && sleep 100s"
ports:
- 1603:1603
volumes:
- shared_repository:/e2e-shared
selenium-hub:
image: selenium/hub
container_name: selenium-hub
ports:
- "4444:4444"
chrome:
image: selenium/node-chrome-debug
container_name: chrome
volumes:
- /dev/shm:/dev/shm
ports:
- "5900:5900"
depends_on:
- selenium-hub
environment:
- HUB_HOST=selenium-hub
- HUB_PORT=4444
- CHROME_DRIVER_VERSION=chromedriver_81.0.4044.69
protractor:
image: node:12.14
container_name: protractor
working_dir: /e2e/
volumes:
- .:/e2e
ports:
- "9229:9229"
command: bash -c "npm install && npm i protractor && ./node_modules/protractor/bin/webdriver-manager update && ls -haltr && node node_modules/protractor/bin/protractor e2e/protractor.conf.js --cucumberOpts.tags=@docker"
depends_on:
- selenium-hub
- chrome
volumes:
shared_repository:

执行docker-compose up时，出现错误通知：

[09:09:18]I/launcher-运行WebDriver量角器的1个实例
|[09:09:17]I/direct-直接使用ChromeDriver。。。量角器

这个项目有一些误解，但我认为主要问题是您使用的是本地Web驱动程序，而不是您提出的Selenium Hub实例。我认为我们可以将docker-compose.yaml文件简化为：

version: '2.4'
services:
selenium-hub:
image: selenium/hub
container_name: selenium-hub
ports:
- "4444:4444"
chrome:
image: selenium/node-chrome-debug
container_name: chrome
volumes:
- /dev/shm:/dev/shm
ports:
- "5900:5900"
depends_on:
- selenium-hub
environment:
- HUB_HOST=selenium-hub
- HUB_PORT=4444
- CHROME_DRIVER_VERSION=chromedriver_81.0.4044.69
protractor:
image: node:12.14
container_name: protractor
ports:
- "9229:9229"
command: bash -c "apt update && apt install -y git && git clone -b main https://github.com/AlfredoBazo/opwDocker.git && cd opwDocker && npm install && node node_modules/protractor/bin/protractor e2e-tests/protractor.conf.js --cucumberOpts.tags=@docker"
depends_on:
- selenium-hub
- chrome

您需要修改您的量角器.conf.js，添加以下行：

seleniumAddress: 'http://selenium-hub:4444/wd/hub'

并删除下一个：

directConnect: true

无论如何，我将包括一些其他的更改，这将是必要的，使它在这个拉请求中运行
