🔹 103. What is WebDriver – Interface or Class?

WebDriver is an interface provided by Selenium that represents the core methods used to automate browsers. Classes like ChromeDriver, FirefoxDriver implement this interface.

---

🔹 104. What is the Super Interface of WebDriver?

The SearchContext interface is the super interface of WebDriver. It contains the basic methods: findElement() and findElements().

---

🔹 105. What is WebElement & Methods in Selenium?

WebElement represents HTML elements. It has several methods like:

• click()

• tagName
• linkText
• partialLinkText
• xpath
• cssSelector

Preferred: id for speed and reliability.

🔹 107. How to Check Whether Object is Present in GUI?

boolean isPresent = driver.findElements(By.id(“elementId”)).size() > 0;

---

🔹 108. How to Check Text from the UI?

String text = driver.findElement(By.id(“elementId”)).getText();

---

🔹 109. How to Capture Element Color, Height, Width, Font-size?

String color = element.getCssValue(“color”);

String height = element.getCssValue(“height”);

String width = element.getCssValue(“width”);

String fontSize = element.getCssValue(“font-size”);

---

🔹 110. How to Get the Location of a WebElement?

Point location = element.getLocation();

int x = location.getX();

int y = location.getY();

---

🔹 111. How to Check if Object is Selected?

boolean selected = element.isSelected();

---

🔹 112. How to Check if Object is Enabled?

boolean enabled = element.isEnabled();

---

🔹 113. How to Delete All Cookies in WebDriver?

driver.manage().deleteAllCookies();

---

🔹 114. Do We Use Constructors in WebDriver?

No. We don’t define custom constructors in WebDriver usage. But internally, the driver classes like ChromeDriver have constructors.

---

🔹 115. How to Compare Two Images in Selenium?

Use OpenCV, Sikuli, or BufferedImage class in Java for pixel-by-pixel image comparison.

---

🔹 116. How to Get WebElement Height and Width?

Dimension size = element.getSize();

int height = size.getHeight();

int width = size.getWidth();

---

🔹 117. What is Synchronization in Selenium?

Synchronization is the process of matching the execution speed of Selenium with the application’s load time. It avoids ElementNotVisibleException.

---

🔹 118. How to Handle Synchronization in Selenium?

Using different wait mechanisms:

• Implicit Wait
• Explicit Wait
• Fluent Wait
• Thread.sleep (not recommended)

---

🔹 119. Which Wait is Used for Page Load?

driver.manage().timeouts().pageLoadTimeout(30, TimeUnit.SECONDS);

---

🔹 120. How to Handle Dynamic Objects?

Strategies:

• Use dynamic XPath
• Wait for element visibility
• Use contains(), starts-with() functions
