Detailed explanation about Selenium WebDriver methods and classes

Selenium WebDriver is a powerful tool for automating web browser interactions. It provides a rich set of classes and methods for interacting with web elements, handling browser actions, and performing various operations programmatically. Below is a detailed explanation of Selenium WebDriver's key methods and classes.

---

Core Classes in Selenium WebDriver

1. WebDriver

• Represents the primary interface for controlling the browser.
• Methods in this class allow you to open, navigate, and manipulate the browser.

2. WebElement

• Represents an element in the DOM.
• Provides methods to interact with elements, such as clicking, entering, retrieving, etc.

3. By

• Used to locate elements on a web page.
• Examples include locating elements by ID, name, class name, CSS selector, XPath, etc.

4. Options

• Represents browser-specific options such as setting preferences and capabilities for a browser (e.g., ChromeOptions, FirefoxOptions).

5. Actions

• Used to perform advanced interactions like drag-and-drop, hover, or composite actions involving multiple steps.

6. ExpectedConditions

• Contains predefined conditions used  WebDriverWait to define explicit waits.

7. WebDriverWait

• Used to implement explicit waits, ensuring synchronization by waiting for specific conditions before proceeding.

Commonly Used WebDriver Methods

Browser Navigation

1. get(String url)

   • Opens the specified URL in the browser.
   • Example:

     driver.get("https://example.com");
     

2. navigate().to(String url)

   • Similar to get() but part of the navigate API.
   • Example:

     driver.navigate().to("https://example.com");
     

3. navigate().back()

   • Navigate to the previous page in the browser history.
   • Example:

     driver.navigate().back();
     

4. navigate().forward()

   • Moves forward in the browser history.
   • Example:

     driver.navigate().forward();
     

5. navigate().refresh()

   • Refreshes the current page.
   • Example:

     driver.navigate().refresh();
     

Interacting with Web Elements

1. findElement(By locator)

   • Locates a single web element.
   • Example:

     WebElement element = driver.findElement(By.id("username"));
     

2. findElements(By locator)

   • Locates multiple elements, returning a list of WebElement.
   • Example:

     List<WebElement> links = driver.findElements(By.tagName("a"));
     

3. click()

   • Clicks the element.
   • Example:

     element.click();
     

4. sendKeys(CharSequence keysToSend)

   • Sends input to an element (e.g., a text box).
   • Example:

     element.sendKeys("test input");
     

5. getText()

   • Retrieves the text of an element.
   • Example:

     String text = element.getText();
     

6. getAttribute(String attributeName)

   • Retrieves the value of an element's attribute.
   • Example:

     String value = element.getAttribute("href");
     

7. isDisplayed()

   • CCheckif an element is visible.
   • Example:

     boolean visible = element.isDisplayed();
     

8. isEnabled()

   • ChCheckf an element is enabled for interaction.
   • Example:

     boolean enabled = element.isEnabled();
     

Window and Frame Handling

1. switchTo().window(String handle)

   • SwiSwitchntrol to a different window.
   • Example:

     driver.switchTo().window(windowHandle);
     

2. switchTo().frame(int index)

   • Switches to a frame by index.
   • Example:

     driver.switchTo().frame(0);
     

3. switchTo().defaultContent()

   • Switches back to the main page from an iframe.
   • Example:

     driver.switchTo().defaultContent();
     

Window Management

1. getWindowHandle()

   • Retrieves the current window handle.
   • Example:

     String handle = driver.getWindowHandle();
     

2. getWindowHandles()

   • Retrieves all open window handles.
   • Example:

     Set<String> handles = driver.getWindowHandles();
     

3. manage().window().maximize()

   • Maximizes the browser window.
   • Example:

     driver.manage().window().maximize();
     

4. manage().window().getSize()

   • Retrieves the size of the browser window.
   • Example:

     Dimension size = driver.manage().window().getSize();
     

---

Synchronization (Waits)

1. Implicit Wait

   • This applies to a global wait for locating elements.
   • Example:

     driver.manage().timeouts().implicitlyWait(Duration.ofSeconds(10));
     

2. Explicit Wait

   • Waits for a specific condition.
   • Example:

     WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(10));
     WebElement element = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("username")));

---

Action Class Methods

1. moveToElement(WebElement target)

   • Moves the mouse to the specified element.
   • Example:

     Actions actions = new Actions(driver);
     actions.moveToElement(element).perform();

2. dragAndDrop(WebElement source, WebElement target)

   • Performs a drag-and-drop action.
   • Example:

     actions.dragAndDrop(sourceElement, targetElement).perform();
     

3. doubleClick(WebElement target)

   • Double-clicks on an element.
   • Example:

     actions.doubleClick(element).perform();

Example Usage

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
public class SeleniumExample {
    public static void main(String[] args) {
        System.setProperty("webdriver.chrome.driver", "path/to/chromedriver");
        WebDriver driver = new ChromeDriver();
        // Open URL
        driver.get("https://example.com");
        // Locate element
        WebElement inputBox = driver.findElement(By.id("inputField"));
        // Interact with element
        inputBox.sendKeys("Selenium WebDriver");
        // Submit form
        inputBox.submit();
        // Close browser
        driver.quit();
    }
}
