selenium-grid2-api

This is an attempt to document the Grid2 API endpoints, along with some code to interact with same and give some sample custom proxies, html renderers and capability matchers. Oh, and some servlets too.

Grid2 available endpoints:

  • /grid/console/
  • /grid/beta/console/
  • /grid/register/
  • /grid/driver/
  • /wd/hub/
  • /selenium-server/driver/
  • /grid/resources/
  • /grid/api/proxy/
  • /grid/api/hub/
  • /grid/api/testsession/
  • /lifecycle-manager/

console

  • /grid/console/
  • /grid/beta/console/

This is the default view of the grid, showing the connected nodes and their test slots both free and busy.
