Click on JDK installations and configure JDK as in the following screenshot:

Step 8) Go to the Build section of new job.
  • In the Root POM textbox, enter full path to pom.xmlin
  • In Goals and options section, enter "clean test"

Step 9) Click on Apply button.
Step 10) On the WebdriverTest project page, click on the Build Now link.
Maven will build the project. It will then have TestNG execute the test cases.

Step 14). Select specific build, and you will see the current status by clicking on "console output".

Scheduling Jenkins for automatic execution.

Scheduling builds(Selenium Tests) is one of the important features of Jenkins where it automatically triggers the build, based on defined criteria. Jenkins provides multiple ways to trigger the build process under the Build Trigger configuration.
For example:
Enter 0 23 * * * in the Schedule textbox as shown in the following screenshot. This will trigger the build process every day at 11 p.m.

Using Jenkings without Maven

To run pure TestNg script in Jenkins, enter the following in build
D:>java -cp "Pathtolibfolder\lib\*;Pathtobinfolder\bin" org.testng.TestNG testng.xml
  • Click on Save button.
  • Note: The actual path of lib and bin folder need to add in above command.
  • After saving the command, Jenkins will build project in predefined time, and this command will be run using TestNG.
  • Result will be stored in custom report HTML file that can be sent via email with a Jenkin configuration
  • Output of the code will be

Benefits of using Jenkins

  1. Early issue finding – Bug can be detected in early phase of the software development
  2. Automatic integration – no separate effort required to integrate all changes
  3. Installer – a deployable system available at any point of development
  4. Records – part build records maintained
  5. Support and Plugins: One of the reasons for Jenkin's popularity is the availability of large community support. Also, lots of ready-made plugins are available which help you expand its functionality.
