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.

When to Use It
There’s two reasons why you might want to use Selenium-Grid.

1)To run your tests against multiple browsers, multiple versions of browser, and browsers running on different operating systems.
2)To reduce the time it takes for the test suite to complete a test pass.
3)Selenium-Grid is used to speed up the execution of a test pass by using multiple machines to run tests in parallel.

How Selenium-Grid Works–With a Hub and Nodes¶

The hub receives a test to be executed along with information on which browser and ‘platform’ (i.e. WINDOWS, LINUX, etc) where the test should be run. It ‘knows’ the configuration of each node that has been ‘registered’ to the hub. Using this information it selects an available node that has the requested browser-platform combination. Once a node has been selected, Selenium commands initiated by the test are sent to the hub, which passes them to the node assigned to that test. The node runs the browser, and executes the Selenium commands within that browser against the application under test.

When I am giving
for node in batch file and running it after hub one it is giving error could find or load main class.
but this same command when hitting in cmd directly it is working.
what could be the problem?

Thanks
In Grid.xml, firefox is also mentioned but why its not executed !

After registering the nodes, I wrote a script and tried to run it. But I am observing that grid console is not opening - ERR_CONNECTION_TIMED_OUT is seen
