Continuous Integration is on trend so is the DevOps. You would have mastery over Selenium WebDriver or Automation Framework development, but all your knowledge is incomplete without the knowledge of the DevOps or Continous Integration. It has an added benefit to your knowledge. Today not only testing processes are in automation, rather the entire lifecycle automated and it became possible when Development, Operations and other Stakeholders came under the same umbrella which we call as DevOps. Basically, we connect other tech environments with the help of pipeline and the status of the pipeline tracked and triggered through the build. Continuous integration tool generated these builds. There are some paid and free tools available. Some of the tools are- Jenkins, Bamboo, Team City, etc.
Jenkins, the most popularly used CI tool. Today we are going to discuss this wonderful tool and its configuration with your Maven project. We will also see how builds are triggered automatically when we run our test in Eclipse and Test results validation after doing the manual run of the build in Jenkins.

What is Jenkins?
Jenkins is a CI (Continuous Integration) tool which is written in Java. This is a Hudson project which is basically an open source. It offers services like Continuous delivery and Integration.
We can use on Windows, Linux, Mac OS etc environment.
Now one question comes in our mind that why we use Jenkins in selenium.
The answer is if the software changes or deployed in a new environment Jenkins is able to run test scripts every time to ensure whether the code is the break or not. That’s why Jenkins is called continuous integration tool. We can also schedule our test script at the specific time and it generates the test report as well.
How to download and configure the Jenkins?

How to set up periodic builds in Jenkins?
If you want to run your build for specific time interval then go to build triggers and select build periodically by entering the job pattern.
Click on apply and save
I entered * * * * * which means it will run my job every minute
Explanations of above build logic/pattern
Let’s say we assign each star some numeric position (first, second,..) for our convenience to explain this logic So here the first star denotes minute whose range is between 0 to 59. Similarly, the second star denotes hour with range from 0 to 23, the third star denotes the day of the month which lies between 1 to 31, fourth star means that the month whose range lies between 1 to 12 and the fifth the last star denotes day of the week whose range is between 0 to 6 (Sunday to Saturday).
How to configure email in Jenkins build?

I have created a simple project which will validate the title of Google homepage
Here is the above code, if you wish to use it:
package tests;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.Assert;
import org.testng.annotations.Test;
public class FirstTest {
private WebDriver driver;
@Test
public void testEasy() {
System.setProperty("webdriver.chrome.driver","C:\\Users\\abc\\Desktop\\Selenium\\chromedriver_win32\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.get("http:www.google.com");
String actualtitle = driver.getTitle();
String expectedTitle="Google";
Assert.assertEquals(actualtitle, expectedTitle, "The expected title matched");
System.out.println("################Actual:"+actualtitle+ "Expected:"+expectedTitle+"#################");
driver.close();
driver.quit();
}
}
Click on Console Output to see the results of the build and test as well.
Here is the result.
