Selenium WebDriver Commands

Selenium WebDriver commands can be classified as Get commands, Navigation commands, WebElement commands, Action commands, and Result commands.

Get Commands - Get commands are the most commonly used commands to perform the basic operations of WebDriver such as opening a browser, performing a few tasks, and then closing the browser.

Syntax: get(String arg) : void

The get() method takes a string URL as a parameter and returns nothing.

Syntax:

1

  driver.get(https://www.google.com);

Example - 

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

// Or It can be also written as 

String URL = "https://www.scientecheasy.com"; 

driver.get(URL);

Get Current URL -   The getCurrentURL() method takes nothing as a parameter and returns URL of the web page currently loaded in the browser.

getCurrentUrl() : String

Syntax:
driver.getCurrentUrl();

Example - 

driver.getCurrentUrl(); 

// The above code can be also written as 

String currentUrl = driver.getCurrentUrl(); 

// Since the return type of getCurrentUrl() method is String. So, we will store it using variable currentUrl with String data type.

Get Title Command - The getTitle() method takes nothing as a parameter and returns the page title of the currently loaded web page. If the web page has no title, it will return a null String.

getTitle() : String

Syntax:
driver.getTitle();

Example - 

driver.getTitle(); 

// The above code can also be written as 

String title = driver.getTitle(); // Return type of getTitle is String.

Get Page Source Command-  The getPageSource() method accepts nothing as a parameter and returns the source code of the current web page. This method is used to get the page source code of the currently loaded web page.

Syntax:

driver.getPageSource();

Example - 

driver.getPageSource(); 

// Or 

String pageSource = driver.getPageSource();

// Since return type of the this method is String. Therefore, the output must be stored in a variable with datatype String.

Get Text Command -   The getText() method accepts nothing as a parameter and returns a string value. This method is used to retrieve the inner text of the specified element.

getText() : String

Syntax:

driver.findElement(By.locatorName(“Specified Element”)).getText();

Example - 

String text = driver.findElement(By.id("India")).getText(); // id is name of locator. India is a specified element. 

System.out.println(text); 

// The above code can also be written as 

WebElement element=driver.findElement(By.id("India")); 

String text=element.getText(); // Return type of getText method is String. 

System.out.println("Inner Text: " +text);

Get Tag Name Command- The getTagName() method takes nothing as a parameter and returns a String value. This method is used to get the tagName of the WebElement returned by the findElement(By) method.

getTagName() : String

Syntax:
element.getTagName(); // Here. element is a variable whose return type is WebElement.

Example -

String tagName = driver.findElement(By.id("DownloadButton")).getTagName(); 

// or 

WebElement element = driver.findElement(By.id("DownloadButton")); 

String tagName = element.getTagName(); 

System.out.println(tagName);

Get CSS Value Command- The getCssValue() method accepts nothing as a parameter and returns a String value. This method is used to fetch the value of the CSS property of the given web element when it is invoked.

getCssValue() : String

Syntax:
element.getCssValue();

Get Attribute Command -  The getAttribute() method takes the String as a parameter and returns a String value. It is used to fetch or get the value of the attribute of the WebElement.

getAttribute(String Name) : String

Syntax:
element.getAttribute();

Example - 

WebElement element = driver.findElement(By.id("DownloadButton")); 

String attributeValue = element.getAttribute("id"); //This will return "DownloadButton". 

System.out.println(attributeValue);

Get Size Command-  The getSize() method does not accept any parameter but returns the size of the element on the page. This method is used to fetch the width and height of the rendered element.

getSize() : int

Syntax:
element.getSize();

Example - 

WebElement element = driver.findElement(By.id("DownloadButton")); 

Dimension elementSize = element.getSize(); 

System.out.println(“Height :” + elementSize.height + ”Width : "+ elementSize.width);

Close Command - The close method takes nothing as a parameter and returns nothing. This method is used to close only the browser window that web driver is currently controlling.

close() : void

Syntax:
driver.close();

Quit Command - The quit() method accepts nothing as a parameter and returns nothing. This method is used to close all windows opened by WebDriver.

quit() : void

Syntax:
driver.quit();

Basic steps of Selenium testing and its widely used commands via a practical application.

Basic steps of Selenium testing and its widely used commands via a practical application.

Selenium testing can be divided into the following seven basic elements:

Creating an instance of a web driver: This is the first step for all the usages of a Selenium webdriver API. An instance of a webdriver interface is created using a constructor of a particular browser. This webdriver instance is used to invoke methods and to access other interfaces. Following are the most commonly used commands for initializing a web driver:

Firefox:
WebDriver driver = new FirefoxDriver();

Chrome:
WebDriver driver = new ChromeDriver(); 

Safari Driver:
WebDriver driver = new SafariDriver(); 

Internet Explorer: 
WebDriver driver = new InternetExplorerDriver(); 

Navigating to a webpage: The second step after initializing an instance of a webdriver, to navigate to a particular webpage we want to test. Following are the most commonly used commands for webpage navigation:

Navigate to URL: 
driver.get(“https://www.interviewbit.com”) 
driver.navigateo.to(“https://www.interviewbit.com”) 

Refresh page:
driver.navigate().refresh()

Navigate forward in browser history:
driver.navigate().forward()

Navigate backward in browser history:
driver.navigate().backward()

Locating an HTML element on the webpage: To interact with a web element and perform actions on it like clicking a button or entering text, we first need to locate the desired elements such as the button or the textbox on the web page. Following are the most commonly used commands for web element navigation:

Locating by ID:
driver.findElement(By.id("q")).sendKeys("Selenium 3");

Location by Name:
driver.findElement(By.name("q")).sendKeys ("Selenium 3");

Location by Xpath:
driver.findElement(By.xpath("//input[@id==’q’])).sendKeys("Selenium 3");

Locating Hyperlinks by Link Text:
driver.FindElement(By.LinkText("edit this page")).Click();

Locating by ClassName
driver.findElement(By.className("profileheader"));

Locating by TagName
driver.findElement(By.tagName("select')).click();

Locating by LinkText
driver.findElement(By.linkText("NextPage")).click();

Locating by PartialLinkText
driverlindElement(By.partialLinkText(" NextP")).click();

Performing actions on an HTML element: Once we have located the HTML element, the next step is interacting with it. Following are the most commonly used commands for performing actions on HTML element:

Entering a username
usernameElement.sendKeys("InterviewBit");

Entering a password
passwordElement.sendKeys("Raw");

Submitting a text input element
passwordElement.submit(); 

Submitting a form element:
formElement.submit();  

Anticipating browser response from the action: Once an action is performed, anticipating a response from the browser to test comes under this step. It takes a second or two for the action to reach the browser, and hence wait is often required for this step. There are two main types of wait conditions:

• Implicit Wait: It sets a fixed, definite time for all the webdriver interactions. It’s slightly unreliable as web driver response times are usually unpredictable.

Eg: driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

• Explicit Wait: This type of wait condition sets an expected condition to occur on the web page or a maximum wait time for all the webdriver interactions.

Eg: WebElement messageElement = wait.until(ExpectedConditions.presenceOfElementLocated(By.id("loginResponse")) );

Running tests and recording their results using a test framework: in this step, we run tests in an automated test script to evaluate an application's function and performance. Various test frameworks are used for this step, such as:

• JUnit for Java
• NUnit for C#
• Unittest or Pyunit for Python
• RUnit for Ruby

Most frameworks use some sort of asset statement to verify their test results from the expected results.

Eg: assertEquals (expectedMessage, actualMessage);

Concluding a test: In this step, we conclude a test by invoking a quit method on the driver variable. This step closes all the webpages, quits the WebDriver server, and releases the driver.

Eg: driver.quit();

The following is an example of an app that covers all the steps mentioned above:

import org.openqa.selenium.By,
import org.openqa.selenium.WebElement, 

import org.openqa.selenium.support.ni.ExpectedConditiof, 

import org.openqa.selenium.support.ni.WebOriverWait,

import org.junit.Assert;

public class Example {

public static void main(String[] args) {

// Creating a driver instance
WebDriver driver = new FirefoxDriver(), 

// Navigate to a web page
­driver.get("http://www.foo.com");

// Enter text to submit the form
WebElement usernameElement = driver.findElement( By.name("username"));
WebElement passwordElement = driver.findElement(By.name(”password"));
WebElement formElement = driver.findElement(By.id(”loginForm")); 

usernameElement.sendKeys("Scaler Academy");
passwordElement.sendKeys("Raw"); 

formElement.submit();      // submit by form element 


//Putting an explicit wait
WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement messageElement = wait.until(
       ExpectedConditions.presenceofElementLocated(By.id(”loginResponse")) 
       ) ; 

// Run a test
String message = messageElement.getrept();
String successMsg = "Welcome to foo. You logged in successfully.”;
Assert.assertEquals (message, successMsg); 

// Conclude a test
driver.quit();
}
}

Demonstrating usage of Selenium through a test application.

Demonstrating usage of Selenium through a test application.

The following prerequisites to run a demo Selenium test script:

• Java SDK in our respective Operating System.
• A Java-based IDE such as Eclipse or IntelliJ.
• A Selenium Web Driver to be added as a dependency to Java IDE.

package DemoTest;
 
import org.openqa.selenium.firefox.FirefoxDriver;
 
import org.openqa.selenium.WebDriver;
 
 
public class MyFirstTestClass {
 
 
  public static void main(String[] args) throws InterruptedException {
 
//It sets the system property to the given value.
System.setProperty("webdriver.gecko.driver","D:\\Softwares\\geckodriver.exe”);        
 
WebDriver driver = new FirefoxDriver();
 
          driver.get("https://www.google.com/");
 
          //Launch website in the browser 
          driver.manage().window().maximize();
 
  //The sleep pauses the execution of the thread for 5000 ms.
          Thread.sleep(5000);
 
          driver.quit();
 
  }
 
}

Once we run the above script in a Java IDE, we’ll get the following execution logs displayed in your IDE window.
