docker - Windows docker容器中的 Selenium 因ff/chrome “session deleted because of page crash”而失败

Question

带有 Selenium 和ASP.NET 4.5 MVC的DOCKER

我想做什么？

尝试具有以下的docker镜像。是的，我知道还有其他方法可以在此处完成最终游戏，但是我对此有特定要求。

运行ASP.NET MVC 4.5 Web应用程序

通过C#控制台exe具有selenium驱动程序，测试代码

当前状态-在常规Windows 10或Windows 2016中运行测试时，它运行良好。当测试在Windows docker容器中运行时，测试失败，并显示“ session 由于页面崩溃而被删除”。请注意，我专注于chrome测试，但是使用FireFox也会得到相似的结果。

我打开了 Selenium Chrome 的详细调试程序，并捕获了日志文件。我有两个日志文件。 “goodrun_log.txt”来自Windows 10成功测试。 “docker_log.txt”是容器内运行失败的日志。

关于第473行，我们可以看到Docker运行失败。至此，日志文件与正常运行完全相同。然后繁荣。那么，我们缺少什么使Docker容器在此时失败？

在 https://github.com/SeleniumHQ/selenium/issues/7165发布到Selenium
通过 https://github.com/Microsoft/aspnet-docker/issues/181发布到ASP.NET docker repo

与SEEMS类似

TRY IT YOURSELF

There is a docker image with Windows, IIS, Chrome, FF and some tests at https://cloud.docker.com/repository/docker/jhealy62/devfish .

Pull it down the repo and provision it

• docker pull jhealy62/devfish
• docker run -d --name aspnettest -p 5000:80 jhealy62/devfish

Powershell into the container

• docker exec -it aspnettest powershell

Inside the docker container, see the web server working

• curl http://localhost -UseBasicParsing

See the seleniumtest failing:

• cd \
• cd \seleniumtests
• .\SeleniumDockerTests.exe http://localhost

Cry with me!

NEXT STEPS

• POSTED ISSUE - Aspnet docker github - https://github.com/Microsoft/aspnet-docker/issues/181

WHAT HAPPENED TO THE PAGE TIMEOUT ISSUE?

WebDriver Timeout error resolved -Occurs with either FireFox or Chrome tests inside docker container. FIX (requires both items below):

• Install websocket's into the docker container. Excerpt from dockerfile:

RUN powershell -Command Add-WindowsFeature Web-WebSockets

将一组非常有趣的选项传递给chromedriver。

option.AddArguments( "--headless","--disable-gpu", "--no-sandbox" );

Answer 1

以防万一我将解决方案留在这里，也许对某人有帮助)

因此，其想法是在单独的容器中运行“Selenium/standalone-chrome”图像。

首先，设置您的“docker-compose.yml”文件，如下所示:

version: '3.8'
services:
 chrome:
    image: <your_storage>/standalone-chrome
    restart: always
    ports: 
      - 4444:4444
    networks:
     front:
        ipv4_address: 172.16.238.5
 net-worker:
    build: <your_storage>/<your_project>
    depends_on: 
      - chrome
    networks:
     front:
        ipv4_address: 172.16.238.10 

  networks:
   front:
    driver: bridge
    ipam:
        config:
         - subnet: 172.16.238.0/24

然后在代码中只需连接到现有的chrome实例

var options = new ChromeOptions();
options.AddArguments("--headless");
options.AddArgument("no-sandbox");
_chrome = new RemoteWebDriver(new Uri("http://172.16.238.5:4444/wd/hub"), options);

现在，您可以使用此chrome实例上传您的网站进行测试。
