Locating Strategies- (By CSS-Tag and Attribute)

In this section, you will learn how to locate a particular web element using CSS - Tag and Attribute Selector.

As we know that locating a particular web element involves inspection of its HTML codes.

Follow the steps given below to locate the Textbox on the sample web page.

• Open URL: https://www.testandquiz.com/selenium/testing.html
• Right click on the Textbox on the sample web page and select Inspect Element

• It will launch a window containing all the specific codes involved in the development of the Text box.

• Take a note of its Tag and Attribute.

Note: You can choose attributes such as id, class and name along with their values when you are locating through CSS - Tag and Attribute Selector.

• Here, we will take a note of its tag and value of its id attribute.

The Java Syntax for locating a web element through CSS - Tag and Attribute Selector is written as:

driver.findElement(By.cssSelector("Tag[Attribute=value]"))

Therefore, for locating the Textbox on the sample web page we will use the input tag with id attribute:

driver.findElement(By.cssSelector("input[id=fname]"))

Similarly, for locating the Submit button on the sample web page we will use the button tag with id attribute:

driver.findElement(By.cssSelector("button[id=idOfButton]"))

We have created a sample script for you to get a better understanding of how to use CSS - Tag and Attribute Selector. We have embedded comments in each section of code which will guide you through whole automation process.

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.remote.DesiredCapabilities;

public class SampleThree {

	public static void main(String[] args) {
		
	 // System Property for Gecko Driver 
System.setProperty("webdriver.gecko.driver","D:\\GeckoDriver\\geckodriver.exe" );
		
       // Initialize Gecko Driver using Desired Capabilities Class
		DesiredCapabilities capabilities = DesiredCapabilities.firefox();
		capabilities.setCapability("marionette",true);
		WebDriver driver= new FirefoxDriver(capabilities);
		
	
      // Launch Website
driver.navigate().to("https://www.testandquiz.com/selenium/testing.html");
	
      // Click on the textbox and send value
driver.findElement(By.cssSelector("input[id=fname]")).sendKeys("Selenium Tutorials");
	 
	// Click on the Submit button using click() command
driver.findElement(By.cssSelector("button[id=idOfButton]")).click();
 
		
	 // Close the Browser
	         driver.close();
	
	}
