在 Selenium docker 网格 4 中添加 instance/concurrent 会话无效

Question

我已经配置了以下 yml 文件，它启动了每个节点的多个实例并且所有节点都正确启动。

version: "3"
services:
  selenium-event-bus:
    image: selenium/event-bus:4.0.0-rc-1-prerelease-20210804
    container_name: selenium-event-bus
    ports:
      - "4442:4442"
      - "4443:4443"
      - "5557:5557"

  selenium-sessions:

    container_name: selenium-sessions
    ports:
      - "5556:5556"
    depends_on:
      - selenium-event-bus
    environment:

    depends_on:
      - selenium-event-bus
    environment:
      - SE_EVENT_BUS_HOST=selenium-event-bus

      - SE_EVENT_BUS_SUBSCRIBE_PORT=4443

  selenium-distributor:

    depends_on:
      - selenium-event-bus
      - selenium-sessions
      - selenium-session-queue
    environment:
      - SE_EVENT_BUS_HOST=selenium-event-bus
      - SE_EVENT_BUS_PUBLISH_PORT=4442
      - SE_EVENT_BUS_SUBSCRIBE_PORT=4443
      - SE_SESSIONS_MAP_HOST=selenium-sessions
      - SE_SESSIONS_MAP_PORT=5556
      - SE_SESSION_QUEUE_HOST=selenium-session-queue
      - SE_SESSION_QUEUE_PORT=5559

  selenium-router:
    image: selenium/router:4.0.0-rc-1-prerelease-20210804
    container_name: selenium-router
    ports:
      - "4444:4444"
    depends_on:
      - selenium-distributor
      - selenium-sessions
      - selenium-session-queue
    environment:
      - SE_DISTRIBUTOR_HOST=selenium-distributor
      - SE_DISTRIBUTOR_PORT=5553
      - SE_SESSIONS_MAP_HOST=selenium-sessions
      - SE_SESSIONS_MAP_PORT=5556
      - SE_SESSION_QUEUE_HOST=selenium-session-queue
      - SE_SESSION_QUEUE_PORT=5559

  chrome:
    image: selenium/node-chrome:4.0.0-rc-1-prerelease-20210804
    shm_size: 2gb
    depends_on:
      - selenium-event-bus
    environment:
      - SE_EVENT_BUS_HOST=selenium-event-bus
      - SE_EVENT_BUS_PUBLISH_PORT=4442
      - SE_EVENT_BUS_SUBSCRIBE_PORT=4443
      - NODE_MAX_CONCURRENT_SESSIONS=25
    ports:
      - "6900:5900"

  edge:
    image: selenium/node-edge:4.0.0-rc-1-prerelease-20210804
    shm_size: 2gb
    depends_on:
      - selenium-event-bus
    environment:
      - SE_EVENT_BUS_HOST=selenium-event-bus
      - SE_EVENT_BUS_PUBLISH_PORT=4442
      - SE_EVENT_BUS_SUBSCRIBE_PORT=4443
      - NODE_MAX_CONCURRENT_SESSIONS=15
    ports:
      - "6901:5900"

  firefox:
    image: selenium/node-firefox:4.0.0-rc-1-prerelease-20210804
    shm_size: 2gb
    depends_on:
      - selenium-event-bus
    environment:
      - SE_EVENT_BUS_HOST=selenium-event-bus
      - SE_EVENT_BUS_PUBLISH_PORT=4442
      - SE_EVENT_BUS_SUBSCRIBE_PORT=4443
      - NODE_MAX_CONCURRENT_SESSIONS=50
    ports:
      - "6902:5900"

我想通过使用此命令 NODE_MAX_CONCURRENT_SESSIONS 来增加并发性，但网格 portal/UI 没有反映，所有测试都保留在队列中。

有任何提示可以使其与运行测试并行吗？

Answer 1

目前，Selenium 开发人员在那里重做一些东西，而标志是重做的一部分。您正在使用的属性不再有效。

您需要使用 SE_NODE_MAX_SESSIONS 来为您的 docker 容器设置并发会话数。您可能还需要设置 SE_NODE_OVERRIDE_MAX_SESSIONS=true，因为默认的 false 值将并发会话的最大数量限制为核心数量。

这里我试图保留 up-to date guide to Selenium Grid 4 configuration properties。
