101. Difference between quit() & close() in Selenium
- driver.quit(): Closes all browser windows opened by Selenium and ends the WebDriver session.
- driver.close(): Closes only the current active browser window
🔹 102. How to Maximize & Minimize the Browser in Selenium WebDriver
// Maximize
driver.manage().window().maximize();
// Minimize
driver.manage().window().minimize();
🔹 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()
- sendKeys()
- getText()
- getAttribute()
- isDisplayed()
- isEnabled()
- isSelected()
🔹 106. How Many Locators in Selenium? Which One is Preferred?
Selenium has 8 locators:
- id
- name
- className
- 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
