selenium-node

This role deploys one or more nodes on a host. One node consists of several system services and each node runs on a separate display.

Deployed services per node:

• xvfb: virtual framebuffer X server
• openbox: window manager
• vnc: x11vnc server
• selenium-node: Selenium Server running in node mode

All nodes are then managed by selenium-nodes service.

Role Variables

Along with variables from the common role, this role also uses variables with following defaults:

hub_host: "{{ groups['selenium-hub'][0] }}"
nodes: 4
browser_capabilities:
  -
    browser_name: firefox
    browser_version: ""
firefox_package: firefox
chrome_package: chromium
geckodriver_ver: 0.17.0
chromedriver_ver: 2.30

hub_host variable is by default set to the first host from the selenium-hub group. If your inventory group with Selenium Hub host has a different name, you need to set it to that host. For convenience, it is recommended to use group named selenium-hub for your Hub machine.

Example Playbook

Specifying nodes in the inventory:

[selenium-nodes]
node1.example.com nodes=4
node2.example.com nodes=8

Running a role with our own values:

- hosts: selenium-nodes
  roles:
    - { role: selenium-node, nodes: 8, geckodriver_ver: 0.17.0 }

Putting all variables in a variable file, e.g., group_vars/selenium-nodes:

---
hub_host: "{{ groups['my-hub'][0] }}"
nodes: 6

  -
    browser_name: firefox
    browser_version: "52"
