Question

Accepted Answer

Locators are essential for identifying web elements in automation; their usage prioritizes efficiency and reliability.

1. ID: Unique identifier for elements; fastest and most reliable. Example: driver.findElement(By.id('submitBtn'));
2. Name: Useful for form elements; less reliable than ID. Example: driver.findElement(By.name('username'));
3. Class Name: Targets elements by class; can match multiple elements. Example: driver.findElements(By.className('btn'));
4. Tag Name: Selects elements by HTML tag; less specific. Example: driver.findElements(By.tagName('input'));
5. CSS Selector: Flexible and powerful; can target elements based on CSS properties. Example: driver.findElement(By.cssSelector('.btn.primary'));
6. XPath: Highly versatile; can navigate complex DOM structures. Example: driver.findElement(By.xpath('//div[@class="container"]/button'));
