🏹How to Use Find Element:
1.Learn how to use FindElement and FindElements by XPath in Selenium WebDriver for efficient web automation.
2.Master XPath selectors to locate elements precisely in Selenium WebDriver scripts.
3.Use FindElement to get a single matching element and FindElements to retrieve multiple elements by XPath.
4.Optimize XPath expressions for faster and more reliable Selenium automation testing.
5.Handle dynamic elements in Selenium WebDriver using flexible XPath techniques.
6.Avoid common XPath mistakes to improve the accuracy of element selection in Selenium.
7.Combine XPath functions like contains(), starts-with(), and text() for better element identification.
8.Debug and validate your XPath queries using browser developer tools before using them in Selenium.
9.Use relative XPath over absolute XPath to make your Selenium scripts more robust.
10.Improve test automation efficiency by choosing the right XPath strategies for Selenium WebDriver.
🏹Introduction:
When automating web applications using Selenium WebDriver, interacting with web elements is crucial. Selenium provides two primary methods to locate elements on a webpage:
- FindElement: Used to locate a single web element.
- FindElements: Used to locate multiple elements.
In this guide, we’ll explore these methods, their syntax, use cases, and examples with XPath in Selenium.
🏹1. FindElement in Selenium:
Optimize your Selenium scripts by leveraging XPath selectors for robust and flexible web automation.
Understanding absolute and relative XPath improves element identification in Selenium WebDriver.
Syntax:
WebElement elementName = driver.findElement(By.LocatorStrategy("LocatorValue"));
The FindElement command in Selenium WebDriver takes a By object as a parameter and returns a single WebElement. If multiple elements match the criteria, only the first element found is returned.
🏹Supported Locator Strategies:
- ID
- Name
- Class Name
- Tag Name
- Link Text
- Partial Link Text
- XPath
🏹Example: Finding an Element by Link Text:
WebElement loginLink = driver.findElement(By.linkText("Login"));
🏹Example: Clicking a Radio Button by ID:
package com.sample.stepdefinitions;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class NameDemo {
public static void main(String[] args) {
System.setProperty("webdriver.chrome.driver", "D:\\3rdparty\\chrome\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.manage().window().maximize();
driver.get("http://demo.guru99.com/test/ajax.html");
// Find the radio button for "No" using its ID and click on it
driver.findElement(By.id("no")).click();
// Click on Check Button
driver.findElement(By.id("buttoncheck")).click();
}
}
🏹2. FindElements in Selenium:
XPath in Selenium WebDriver helps identify dynamic web elements with precision for automated testing.
Use FindElement
to locate a single element and FindElements
to fetch multiple matching elements in Selenium.
Syntax:
List<WebElement> elementName = driver.findElements(By.LocatorStrategy("LocatorValue"));
The FindElements command returns a list of WebElements that match the given locator strategy. If no elements are found, an empty list is returned.
Example: Finding Multiple Elements by XPath:
List<WebElement> listOfElements = driver.findElements(By.xpath("//div"));
Example: Retrieving and Printing Radio Button Texts:
package com.sample.stepdefinitions;
import java.util.List;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
public class NameDemo {
public static void main(String[] args) {
System.setProperty("webdriver.chrome.driver", "X://chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.get("http://demo.guru99.com/test/ajax.html");
List<WebElement> elements = driver.findElements(By.name("name"));
System.out.println("Number of elements:" + elements.size());
for (int i = 0; i < elements.size(); i++) {
System.out.println("Radio button text:" + elements.get(i).getAttribute("value"));
}
}
}
🏹3.How to Use Find Element Differences Between FindElement and FindElements:
Feature | FindElement | FindElements |
---|---|---|
Return Type | Returns a single WebElement | Returns a list of WebElements |
If Multiple Matches | Returns the first matched element | Returns all matched elements |
If No Matches | Throws NoSuchElementException | Returns an empty list |
Use Case | Used when you expect a single element | Used when multiple elements are expected |
🏹4. How to Use Find Element Handling NoSuchElementException:
When using findElement
, if the element is not found, Selenium throws a NoSuchElementException. To avoid this, you can:
- Use try-catch block:
try {
WebElement element = driver.findElement(By.id("non-existent-id"));
} catch (NoSuchElementException e) {
System.out.println("Element not found!");
}
- Use findElements to check if elements exist before interacting with them:
List<WebElement> elements = driver.findElements(By.id("non-existent-id"));
if (elements.isEmpty()) {
System.out.println("No elements found.");
}
🏹5. How to Use Find Element Summary:
FindElement
returns a single element and throws an exception if not found.FindElements
returns a list of elements and returns an empty list if no match is found.- XPath and other locator strategies can be used to locate elements effectively.
- Handle exceptions properly to avoid script failures.
