A Comprehensive Guide to Essential Selenium WebDriver Commands
Selenium WebDriver is a popular test automation framework that enables testers to automate web applications and perform end-to-end testing. It offers a wide range of commands that allow testers to interact with web elements, handle different scenarios, and validate application functionality. In this article, we will explore the top Selenium WebDriver commands, as well as a list of 25 more popular commands, with detailed explanations and examples.
Top 7 Selenium WebDriver Commands with Details:
#1) get() Method
The get() method is the starting point for test automation. It launches a new browser and opens the specified URL in that browser instance. This command is commonly used to navigate to the initial page of the application under test.
Example:
driver.get("https://www.example.com");
#2) Locating links by linkText() and partialLinkText()
Selenium provides two methods, linkText() and partialLinkText(), to locate and interact with links on a web page. linkText() matches the exact text of the link, while partialLinkText() matches a partial text of the link.
Example:
WebElement link = driver.findElement(By.linkText("Click here")); link.click();
#3) Selecting multiple items in a dropdown
The Select class in Selenium allows testers to work with dropdown elements. To select multiple items in a multi-select dropdown, we need to use the Select class and the selectByVisibleText() or selectByValue() methods.
Example:
Select dropdown = new Select(driver.findElement(By.id("multi-select-dropdown"))); dropdown.selectByVisibleText("Option 1"); dropdown.selectByValue("value2");
#4) Submitting a form
The submit() method is used to submit a form in Selenium. It is applicable to web elements like text fields and buttons that are inside a form element.
Example:
WebElement searchField = driver.findElement(By.id("search-field")); searchField.sendKeys("Selenium commands"); searchField.submit();
#5) Handling iframes
An iframe is an HTML element that allows embedding another HTML document within the current document. To interact with elements inside an iframe, we need to switch to it using the switchTo() method.
Example:
driver.switchTo().frame("iframeName"); WebElement iframeElement = driver.findElement(By.id("elementInsideIframe"));
#6) close() and quit() methods
The close() method is used to close the current browser window, while the quit() method is used to quit the WebDriver and close all browser windows opened by it.
Example:
driver.close(); // Close the current window driver.quit(); // Close all windows and quit WebDriver
#7) Exception Handling
Selenium may encounter various exceptions during test execution. Handling these exceptions using try-catch blocks is crucial for graceful execution and better error reporting.
Example:

try { WebElement element = driver.findElement(By.id("nonExistentElement")); element.click(); } catch (NoSuchElementException e) { System.out.println("Element not found: " + e.getMessage()); }
