Example - Selenium Grid running simultaneously on two different browsers

Aim:

Demonstrate how Selenium Grid can be used to run simultaneously against two browsers.

Difficulty Level:
High

Prerequisites

• Created project directory should be available under C:\WorkshopFiles folder on PC
• Selenium Grid server downloaded and running
• Ant, JAVA should be installed and should work properly
• TestNG installed and working correctly

What to users learn?
Users can learn how to execute TestNG scripts on the multiple browsers in parallel.


Tips:

• Some Basis knowledge of Ant, Selenium Grid is good in understanding the example.
• Some basis working knowledge of TestNG is good in understanding the Project's directory.

Conclusions:

• Internet explorer and firefox opens up simultaneously and the same selenium Script is executed
• Selenium Grid jar files are utilised in the library
• Selenium Grid Console shows the execution status
• TestNG provides different methods which make it easier to execute across different browsers simultaneously.
• Ant is used to launch Selenium Grid

Solution:
Key Steps

1. Launch the Selenium Grid using Command: >ant launch-hub
2. Launch the Browser and open the URL: http://localhost:4444/console
3. Now launch the instances of browser from following command:

• Ant –Dport=5555 –Denvironment=”*firefox” launch-remote-control
• Ant –Dport=5556 –Denvironment=”*googlechrome” launch-remote-control

5.Open the another Command Terminal.
6.Run the Ant command in execution of created target in build.xml file
7.Scripts would be run in parallel on Firefox and Googlechrome

Here is JAVA script file:
