The Selenium Grid unleashes the full power of Selenium to run multiple automated tests in parallel across multiple platforms. Brian Long demonstrates the use of an open-source framework developed at Virginia Tech to get up and running with a Selenium Grid in about an hour. He begins by discussing the Selenium Grid configuration and then progresses to the installation of the framework. Starting with a clean Selenium installation, Brian uses Git to retrieve and install the open-source Selenium Grid framework, then Maven to build it using the Java JDK. Working from the instructions in the open-source Selenium-Grid-setup project, Brian configures a hub and a node on separate machines. After demonstrating the working grid by running a simple test on the remote nodes, Brian continues with how to use the Selenium IDE to generate tests and integrate them into the Grid by extending the open-source code. Note: There will be some programming!

What does it do?
Provides Hub and Node Config
Provides Sample Test

9. How Do I Get it to Work?
RTFR! (Read the Fine ReadMe!)*
1. Put the grid-setup/hub directory on your
hub (if your hub is a windows box, you'll need
to rename the executable 'starthub' to
something like 'starthub.cmd' and fix the
link).
7

10. How Do I Get it to Work?
2. Put the appropriate grid-setup/*-node
directory/ies on your node/s along with the
selenium-server-standalone-<version>.jar
(if you change the version, change the links
in the startup scripts to match).
8

11. How Do I Get it to Work?
3. Update the JSON configs with the ip of your
hub and the ip of each of your nodes.
(search for *.json – there is one in each of
the *-node directories under selenium-grid-
setupgrid-setup, and named for the operating
system: e.g. nodeconfig-win81.json)
9

12. How Do I Get it to Work?
4. Run grid-setup/starthub on the hub
5. Run grid-setup/startnode-* on your nodes
Done! You have a grid. You can check the
connections from your browser at
http://localhost:4444/grid/console on your
hub machine

13. OK, Now What?
Run the Sample Test:
Nav to grid-test/helpers
Run isgridup.sh
11

14. OK, Now What?
Sample Test Results:
All nodes navigate to address specified in VerifyTest.java
12

15. OK, Now Now What?
Run Your Own Tests on the Grid:
• Use Selenium IDE to generate Java code for your test
• Extend RemoteTest to integrate it into the grid OR just
plug it into VerifyGrid.java
• Run your test on the grid
