What is Selenium :

  • selenium was first created by Jason Huggins in 2004
  • Selenium is a software testing tool which can automate your entire testing phase .

Components of Selenium :

Selenium is a package which has different components for different use cases .

  • Selenium RC It is an web server which acts as an HTTP proxy .
  • Selenium IDE It's just a plugin . Mainly used for recording and playback the script .
  • Selenium Grid Multiple test cases can be executed simentaniously.
  • Selenium WebDriver Main component of selenium which used for cross-platform testing .

Features :

  • Open source .
  • Easy to implement .
  • less hardware usages .
  • multi browser support .
  • different language support .
  • Parallel test execution .

Set up :

  • Download
  • Download the chrome driver (Different browser have diff driver)
  • Install Selenium standalone server

  • Open eclipse

  1. create a new project
  2. right click on it
  3. Navigate to properties
  4. Build paths
  5. click on classpath library .
  6. Add external jar
  7. Navigate to the folder (Where you have downloaded your selenium click on that and under lib folder we have our jar files(executable files) ) .
  8. Apply and close Alt Text

A simple test case written on java :

public class Lunch {

    public static void main(String[] args) {

        System.setProperty("webdriver.chrome.drive", "C://selenium//chromedriver.exe");

       //We need to create the object for our chromedriver
       WebDriver driver =  new chromeDriver();

        driver.get("https://www.facebook.com");
       //Then we can perform Desired testing with driver object
       driver.findElement(By.id("email")).sendKeys("hlw");

       driver.findElement(By.id("pass")).sendKeys("1234");


       driver.findElement(By.name("login")).click();
       }
}
Enter fullscreen mode Exit fullscreen mode

So here we are automating the task we might do manually like

  1. opening the browser .
  2. Insert the credentials .
  3. Then click on Log in .
  • What we are defining Selenium is to go to the Facebook's URL and by using selectors .
  • We can find the selectors by inspecting the page (ctl + shift + i).

  • After Entering the credentials for username and password fields we then click on the login button .

How can we optimize more .

public class Lunch {

    public static void main(String[] args) {

        System.setProperty("webdriver.chrome.driver", "C:\\Selinium\\chromedriver.exe");

        //we need create a object for the chromedriver
        WebDriver driver = new ChromeDriver();

        driver.get("https://www.facebook.com");

        String title =  driver.getTitle(); //Actual title

//      Facebook โ€“ log in or sign 

        if(title.matches("Facebook โ€“ log in or sign up")) {
            System.out.println("valid page");

            driver.findElement(By.id("email")).sendKeys("hlw");
            driver.findElement(By.id("pass")).sendKeys("1234");

            driver.findElement(By.name("login")).click();
        }else {
            System.out.println("Invalid page");

            driver.close();
        }
    }

}
Enter fullscreen mode Exit fullscreen mode

Upon the validity of the mentioned URL we are performing the task otherwise simply close the connection .

we can use TestNg for generating the test reports . where NG means "next generation" . It is a testing framework like Junit .

Features of TestNG :

  • annotations are easy to create test cases .
  • Test case can be grouped by prioritized more easily .
  • It supports parameterization .
  • supports data-driven testing using DataProviders .
  • Generates HTML reports .
  • Parallel test execution is possible .

Annotations in TestNG :

Annotations in TestNG are used to decide the flow of the program .

  • @BeforeSuite
  • @BeforeTest
  • @BeforeClass

Why do we need Maven :

  • Imagine a scenario where we want to give the same test case file to other person then we have to also include the jar files which is time taking because sending a lot of jar files over the internet could be inappropriate .
  • Here we could use Maven .

  • Maven is used to download dependencies for a software program .
  • dependencies are downloaded are included inside a POM file .
  • Once the dependencies are included simply save the project and all the dependencies will automatically downloaded .
