What’s New in Selenium 4?
Selenium 4 has brought several exciting features and improvements, making it even more powerful and user-friendly. Here are some highlights:
1. Improved Selenium Grid
Selenium Grid now supports Docker, allowing you to run tests in isolated containers. This feature streamlines the setup process and makes it easier to manage test environments.
2. Enhanced DevTools Protocol
Selenium 4 leverages the Chrome DevTools Protocol, providing more control over browser features, including network interception, performance monitoring, and more. This improvement enables testers to conduct more sophisticated testing scenarios.
3. New Relative Locators
Selenium 4 introduces relative locators, allowing users to find elements based on their proximity to other elements. This feature simplifies locating elements that may not have unique attributes.
4. Better Documentation
The documentation for Selenium 4 has been revamped to provide clearer guidance, making it easier for new users to understand and utilize the tool effectively.
Selenium Cheat Sheet for Quick Reference
To help you get started with Selenium, here’s a concise cheat sheet covering essential commands and features.
Basic Setup
1. Java Setup
<!-- Add Selenium dependency in Maven -->
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-java</artifactId>
<version>4.x.x</version>
</dependency>2. Python Setup
# Install Selenium using pip
pip install seleniumStarting a WebDriver
Java
WebDriver driver = new ChromeDriver();
driver.get("https://www.example.com");Python
from selenium import webdriver
driver = webdriver.Chrome()
driver.get("https://www.example.com")Locating Elements
1. By ID
WebElement element = driver.findElement(By.id("element_id"));
2. By Class Name
WebElement element = driver.findElement(By.className("class_name"));
3. By XPath
WebElement element = driver.findElement(By.xpath("//tag[@attribute='value']"));
Interacting with Elements
1. Click
element.click();
2. Send Keys
element.sendKeys("Your Text");
3. Clear
element.clear();
Waiting Strategies
Implicit Wait
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
Explicit Wait
WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(10));
WebElement element = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("element_id")));
Taking Screenshots
Java
File screenshot = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
FileUtils.copyFile(screenshot, new File("screenshot.png"));
Python
driver.save_screenshot("screenshot.png")
