在 Selenium docker grid 4 中添加实例/并发会话不起作用

Question

我已经配置了以下 yml 文件，该文件可以启动每个节点的多个实例，并且所有节点都可以正确启动。

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:
    image: selenium/sessions:4.0.0-rc-1-prerelease-20210804
    container_name: selenium-sessions
    ports:
      - "5556:5556"
    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

  selenium-session-queue:

    ports:
      - "5559:5559"
    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

  selenium-distributor:

    container_name: selenium-distributor
    ports:
      - "5553:5553"
    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来增加并发性NODE_MAX_CONCURRENT_SESSIONS，但网格门户/UI 没有反映，所有测试都保留在队列中。

有什么提示可以使其并行运行测试吗？

Answer 1

目前，Selenium 开发人员在那里重新设计了一些东西，而标志是重新设计的一部分。您正在使用的属性不再有效。

您需要使用SE_NODE_MAX_SESSIONS来设置 docker 容器的并发会话数。您可能还需要进行设置，SE_NODE_OVERRIDE_MAX_SESSIONS=true因为默认false值将最大并发会话数限制为核心数。

在这里，我试图保留Selenium Grid 4 配置属性的最新指南。
