3. What is Selenium Grid?
• Selenium-Grid allows you run your tests on
different machines against different browsers
in parallel. That is, running multiple tests at
the same time against different machines
running different browsers and operating
systems. Essentially, Selenium-Grid support
distributed test execution. It allows for
running your tests in a distributed test
execution environment.

• Hub – Implies selenium grid 2 hub which
distributes tests among multiple nodes

• Node – One node represents one machine
where test will be running & we can have
multiple nodes those will be registered with
one centralized hub which will be running on
anyone machine.

• Copying both ‘selenium-server-standalone-
x.x.x.jar’ and ‘webconfig.txt’ on number of
machines/VMs required for testing.
• Run Hub and Nodes.
6. Configuring Grid 2 using webconfig.txt
JSON format configuration file.
