Question

注意：我的问题之前已经关闭，我尝试了这里提到的解决方案-unknown error: session deleted because of page crash from unknown error: cannot determine loading status from tab crashed with ChromeDriver Selenium-添加了这些选项-options.addArguments（“-disable-dev-shm-usage”）; options.addArguments（“-no-sandbox”）; -还是我看到了这个问题

在硒网格中运行之间的某些情况下，看到以下单个测试的错误：

挂钩方法1：

我们在钩子中有3种顺序方法-看起来第一个问题是根本原因，但不确定。

以下是用于驱动程序的选项：

            ChromeOptions options = new ChromeOptions();
            options.addArguments("start-maximized");
            options.addArguments("--disable-infobars");
            options.addArguments("--disable-extensions");
            options.addArguments("chrome.switches", "--disable-extensions");
            options.addArguments("--disable-gpu");
            options.addArguments("--disable-dev-shm-usage");
            options.addArguments("--no-sandbox");
            options.addArguments("--disable-notifications");
            options.addArguments("--disable-popup-blocking");
            options.addArguments("enable-automation");
            options.addArguments("--disable-dev-shm-usage");
            options.addArguments("--disable-browser-side-navigation");
            options.addArguments("--dns-prefetch-disable");
            options.setPageLoadStrategy(PageLoadStrategy.NONE);
            options.setExperimentalOption("useAutomationExtension", false);
            driver = new RemoteWebDriver(new URL(AWS_URL), options);

以下是我们在kubernetest yaml文件中使用的替代：

  chrome:
    ## Enable the creation of a node-chrome pod
    enabled: true
    replicas: 65
    javaOpts: "-Xmx1024m -XX:+UseSerialGC"

 Please help

Answer 1

我遇到了同样的问题，并且通过在docker-compose.yml文件中为chrome容器添加-/ dev / shm：/ dev / shm来解决了该问题
请参阅：https://github.com/SeleniumHQ/docker-selenium

chrome:
 image: selenium/node-chrome
 depends_on:
  - selenium-hub
 volumes:
  - /dev/shm:/dev/shm
 environment:
  HUB_PORT_4444_TCP_ADDR: selenium-hub
  HUB_PORT_4444_TCP_PORT: 4444
  NODE_MAX_SESSION: 2
  NODE_MAX_INSTANCES: 2

Answer 2

对于Chrome和Firefox，我遇到了同样的问题。我能够通过增加两个容器的大小（shm_size）来解决此问题。

version: "3"
services:
  hub:
    image: selenium/hub
    ports:
      - "4444:4444"
  chrome:
    image: selenium/node-chrome
    shm_size: '1gb'
    depends_on:
      - hub
    environment:
      - HUB_HOST=hub
  firefox:
    image: selenium/node-firefox
    shm_size: '1gb'
    depends_on:
      - hub
    environment:
      - HUB_HOST=hub
