WebDriver Scripting

Using the Java class “myclass”  that we created previously, let us try to create a WebDriver script that would:

• Fetch Mercury Tours’ homepage


• Verify its title


• Print out the result of the comparison


• Close it before ending the entire program.

WebDriver Code

Below is the actual WebDriver code for the logic presented by the scenario above:

package mypackage; 
import org.openqa.selenium.WebDriver; 
import org.openqa.selenium.firefox.FirefoxDriver;

public class myclass {

public static void main(String[] args) {

// declaration and instantiation of objects/variables 
 WebDriver driver = new FirefoxDriver(); 
 String baseUrl = "http://newtours.demoaut.com"; 
 String expectedTitle = "Welcome: Mercury Tours"; 
 String actualTitle = "";

// launch Firefox and direct it to the Base URL 
 driver.get(baseUrl);

// get the actual value of the title 
 actualTitle = driver.getTitle();

/*compare the actual title of the page with the expected one and print the result as "Passed" or "Failed"*/

if (actualTitle.contentEquals(expectedTitle)){ 
 System.out.println("Test Passed!"); 
 } else { 
 System.out.println("Test Failed"); 
 }

//close Firefox 
 driver.close();

// exit the program explicitly 
 System.exit(0);
 } 
}

Explaining the code

Importing Packages

To get started, you need to import following two packages:

org.openqa.selenium.*- contains the WebDriver class needed to instantiate a new browser loaded with a specific driver

org.openqa.selenium.firefox.FirefoxDriver – contains the FirefoxDriver class needed to instantiate a Firefox-specific driver onto the browser instantiated by the WebDriver class

If your test needs more complicated actions such as accessing another class, taking browser screenshots, or manipulating external files, definitely you will need to import more packages.

Instantiating objects and variables

Normally, this is how a driver object is instantiated.

WebDriver driver = new FirefoxDriver();

A FirefoxDriver class with no parameters means that the default Firefox profile will be launched by our Java program. The default Firefox profile is similar to launching Firefox in safe mode (no extensions are loaded).

For convenience, we saved the Base URL and the expected title as variables.

Launching a Browser Session

WebDriver’s get() method is used to launch a new browser session and directs it to the URL that you specify as its parameter.

driver.get(baseUrl);

Get the Actual Page Title

The WebDriver class has the getTitle() method that is always used to obtain the page title of the currently loaded page.

actualTitle = driver.getTitle();

Compare the Expected and Actual Values

This portion of the code simply uses a basic Java if-else structure to compare the actual title with the expected one.

if (actualTitle.contentEquals(expectedTitle)){ 
 System.out.println("Test Passed!"); 
 } else { 
 System.out.println("Test Failed"); 
 }

Terminating a Browser Session

The “close()” method is used to close the browser window.

driver.close();

Terminating the Entire Program

If you use this command without closing all browser windows first, your whole Java program will end, while leaving browser window open.

System.exit(0);

Running the Test

There are two ways to execute code in Eclipse IDE.

On Eclipse’s menu bar, click Run > Run.

Press Ctrl+F11 to run the entire code.



If you did everything correctly, Eclipse would output “Test Passed!”
