Selenium WebDriver provides an API (Application Programming Interface) that allows you to interact with web browsers programmatically and automate browser actions. The WebDriver API provides methods and classes to perform various operations such as navigating to web pages, interacting with elements, handling alerts, managing cookies, and more.

Here’s an overview of some commonly used WebDriver API methods:

1. WebDriver Interface: The WebDriver interface serves as the main entry point for interacting with browsers. It provides methods for controlling browser behavior and performing high-level operations. Some commonly used methods include:

   • get(String url): Navigates to a specified URL.
   • getCurrentUrl(): Retrieves the current URL of the page.
   • getTitle(): Retrieves the title of the current page.
   • navigate(): Accesses browser navigation capabilities, allowing you to go back, forward, or refresh the page.
   • manage(): Provides methods to manage browser settings and properties, such as timeouts, window size, and cookies.
   • quit(): Closes the browser and terminates the WebDriver session.

2. WebElement Interface: The WebElement interface represents an element on a web page. It provides methods to interact with and retrieve information from individual elements. Some commonly used methods include:

   • click(): Clicks the element.
   • sendKeys(CharSequence... keysToSend): Enters text into an input field.
   • getText(): Retrieves the visible text of the element.
   • getAttribute(String name): Retrieves the value of the specified attribute of the element.
   • isDisplayed(): Checks if the element is currently visible on the page.
   • isEnabled(): Checks if the element is enabled and can be interacted with.
   • submit(): Submits a form associated with the element.

3. By Class: The By class provides various locator strategies to find elements on a web page. It is used in conjunction with WebElement methods to locate and interact with specific elements. Some commonly used locator strategies include:

   • By.id(String id): Locates an element by its unique ID attribute.
   • By.name(String name): Locates an element by its name attribute.
   • By.className(String className): Locates an element by its CSS class name.
   • By.tagName(String tagName): Locates an element by its HTML tag name.
   • By.linkText(String linkText): Locates a link element with exact text matching.
   • By.partialLinkText(String partialLinkText): Locates a link element with partial text matching.
   • By.xpath(String xpathExpression): Locates an element using XPath expressions.
   • By.cssSelector(String cssSelector): Locates an element using CSS selectors.

These are just a few examples of the methods and classes provided by the Selenium WebDriver API. The API offers a comprehensive set of tools and capabilities for browser automation and interaction. Refer to the official Selenium documentation or specific language bindings documentation (e.g., Selenium WebDriver for Java) for detailed information on the available methods and how to use them in your automation scripts.
