💡 Selenium Locators help WebDriver identify and interact with web elements efficiently. Strong locator knowledge is essential for every Automation Tester.
📌 What are Selenium Locators?
Selenium Locators are methods used to identify HTML elements on a web page so that Selenium WebDriver can perform actions such as click, type, select and validate.
Without locators, Selenium cannot interact with web elements.
📚 Types of Selenium Locators
| Locator | Description |
|---|---|
| ID | Fastest and most reliable locator. |
| Name | Identifies elements using the name attribute. |
| Class Name | Uses CSS class values. |
| Tag Name | Identifies elements using HTML tags. |
| Link Text | Matches exact hyperlink text. |
| Partial Link Text | Matches partial hyperlink text. |
| XPath | Flexible locator using XML paths. |
| CSS Selector | Fast and powerful locator strategy. |
💻 Selenium Locator Example
WebDriver driver = new ChromeDriver();
driver.findElement(By.id("username")).sendKeys("Admin");
driver.findElement(By.name("password")).sendKeys("admin123");
driver.findElement(By.xpath("//button[@type='submit']")).click();
⚔️ XPath vs CSS Selector
| Feature | XPath | CSS Selector |
|---|---|---|
| Speed | Moderate | Faster |
| Backward Traversal | Supported | Not Supported |
| Syntax | Complex | Simple |
