  • Run Selenium server as hub:
java -jar selenium-server-standalone-2.53.1.jar -role hub -port 4444
  • Run Selenium server in nodes:
java -jar selenium-server-standalone-2.53.1.jar -role node -hub http://172.31.22.212:4444/grid/register -Dwebdriver.chrome.driver="C:/Users/Administrator/Desktop/chromedriver.exe" -browser "browserName=chrome,maxInstances=5,maxSessions=5" -port 5556
java -jar selenium-server-standalone-2.53.1.jar -role node -hub http://172.31.22.212:4444/grid/register -Dwebdriver.ie.driver="C:/Users/Administrator/Desktop/IEDriverServer.exe" -browser "browserName=internet explorer,maxInstances=5,maxSessions=5" -port 5557
java -jar selenium-server-standalone-2.53.1.jar -role node -hub http://172.31.22.212:4444/grid/register -browser "browserName=firefox,maxInstances=5,maxSessions=5" -port 5558
  • Linux, get processes list:
  • ps aux | less
  • Linux kill process:
  • Kill -9 PID
  • Linux, download UZIP:
  • sudo yum install unzip


Start Nodes Using JSON File:
You have to create JSON file with these configurations for 3 supported browsers:
{
 "capabilities":
     [
       {
         "browserName": "firefox",
         "maxInstances": 5,
         "seleniumProtocol": "WebDriver"
       },
       {
         "browserName": "chrome",
         "maxInstances": 5,
         "seleniumProtocol": "WebDriver"
       },
       {
         "browserName": "internet explorer",
         "maxInstances": 5,
         "seleniumProtocol": "WebDriver"
       }
     ],
 "configuration":
 {
   "proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
   "maxSession": 5,
   "port": 5556,
   "register": true,
   "registerCycle": 5000,
   "hubPort": 4444,
   "hub": "http://172.31.27.83:4444/grid/register",
   "hubHost": "172.31.27.83"
 }
}
To start the nodes, you have to execute this command:
  • java -jar  selenium-server-standalone-2.53.1.jar -role node -nodeConfig config.json

How to Customize TestNG Emailable Report ?

TestNG emailable reports are too bad and unreadable, in this post I'll illustrate the we send and improve the reports using TestNG IReport listener. The report includes the number of passed, failed, and skipped tests with execution times and test names. If you are using a CI tool such as Jenkins pipeline, you can add a new stage for emailing this report to the dev team. Nightly builds need to be daily supervised by the dev team in your organization so that if you summarise failures with this readable report would be helpful to catch bugs of newly deployed versions. Now I'm sharing the java listener for generating the HTML report with test results. After you add this listener to your java project, you need to add it to your xml runner file like this: <listeners> <listener class-name="automationInfra.com.listeners.CustomizedEmailableReport"> </listener> </listeners> Now we back to Jenkins pipeline send email stage, in y...
