Selenium Java

System.setProperty("webdriver.chrome.driver", [1]);

Drag options to blanks, or click blank then click option'

A"path/to/edgedriver.exe"

B"path/to/geckodriver.exe"

C"path/to/chromedriver.exe"

D"path/to/safaridriver.exe"

💡 Hint

Common Mistakes

Setting the path to the wrong driver executable.

Not using quotes around the path string.

To use ChromeDriver, you must set the system property webdriver.chrome.driver to the path of the ChromeDriver executable.

Fix the error in the code to properly import the ChromeDriver class.

Selenium Java

import org.openqa.selenium.[1];

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Importing FirefoxDriver instead of ChromeDriver.

Missing the import statement entirely.

The correct import for ChromeDriver is org.openqa.selenium.chrome.ChromeDriver.

4fill in blank

hard

Fill both blanks to initialize ChromeDriver and open the URL "https://example.com".

Selenium Java

WebDriver driver = new [1]();
driver.[2]("https://example.com");

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using FirefoxDriver instead of ChromeDriver.

Using navigate without to method.

Create a new ChromeDriver instance and use the get method to open a URL.

5fill in blank

hard

Fill all three blanks to properly quit the ChromeDriver session after opening a page.

Selenium Java

WebDriver driver = new [1]();
driver.[2]("https://example.com");
driver.[3]();

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using close instead of quit which only closes one window.

Not quitting the driver at all.

Use quit to close all browser windows and end the WebDriver session properly.

Practice

1. What is the main purpose of setting up ChromeDriver in Selenium WebDriver tests?

easy

A. To control the Chrome browser automatically during tests

B. To write test cases in Java

C. To create HTML reports for test results

D. To manage database connections

Solution

1. Step 1: Understand WebDriver role

   WebDriver controls browsers to simulate user actions in tests.

2. Step 2: Identify ChromeDriver's function

   ChromeDriver is the specific driver that controls the Chrome browser.

3. Final Answer:

   To control the Chrome browser automatically during tests -> Option A

4. Quick Check:

   ChromeDriver controls Chrome browser [OK]

Hint: ChromeDriver lets Selenium talk to Chrome browser [OK]

Common Mistakes:

• Confusing ChromeDriver with test case writing
• Thinking ChromeDriver creates reports
• Mixing browser control with database tasks

2. Which of the following is the correct way to set the ChromeDriver path in Java before creating a ChromeDriver instance?

easy

A. System.setProperty("webdriver.chrome.driver", "path/to/chromedriver.exe");

B. ChromeDriver.setPath("path/to/chromedriver.exe");

C. WebDriver.chromeDriverPath = "path/to/chromedriver.exe";

D. driver.setChromeDriver("path/to/chromedriver.exe");

Solution

1. Step 1: Recall Java system property syntax

   Setting ChromeDriver path uses System.setProperty with key "webdriver.chrome.driver".

2. Step 2: Match correct method and parameters

   System.setProperty("webdriver.chrome.driver", "path/to/chromedriver.exe"); correctly uses System.setProperty with the driver path string.

3. Final Answer:

   System.setProperty("webdriver.chrome.driver", "path/to/chromedriver.exe"); -> Option A

4. Quick Check:

   Use System.setProperty for driver path [OK]

Hint: Use System.setProperty with key "webdriver.chrome.driver" [OK]

Common Mistakes:

• Using non-existent methods like setPath or setChromeDriver
• Assigning path directly to WebDriver variable
• Missing quotes or wrong method names

3. What will happen if you run the following Java Selenium code snippet?

System.setProperty("webdriver.chrome.driver", "/drivers/chromedriver");
WebDriver driver = new ChromeDriver();
driver.get("https://example.com");
driver.quit();

medium

A. The browser opens but does not navigate to example.com

B. The code throws a syntax error at System.setProperty

C. The Chrome browser opens example.com and then closes

D. The ChromeDriver fails to start due to missing driver path

Solution

1. Step 1: Analyze driver setup and navigation

   System.setProperty sets the driver path correctly, ChromeDriver instance is created, and driver.get opens the URL.

2. Step 2: Check browser closing command

   driver.quit() closes the browser after navigation.

3. Final Answer:

   The Chrome browser opens example.com and then closes -> Option C

4. Quick Check:

   Correct setup opens and closes browser [OK]

Hint: Correct setup opens URL then quits browser [OK]

Common Mistakes:

• Assuming syntax error without checking code
• Thinking driver.get does not open URL
• Forgetting driver.quit closes browser

4. Identify the error in this Selenium WebDriver setup code snippet:

WebDriver driver = new ChromeDriver();
System.setProperty("webdriver.chrome.driver", "/drivers/chromedriver");
driver.get("https://example.com");

medium

A. driver.get() should be called before setting system property

B. System.setProperty must be called before creating ChromeDriver instance

C. ChromeDriver path should be set using driver.setPath()

D. No error, code will run fine

Solution

1. Step 1: Check order of setting driver path

   System.setProperty must be called before creating ChromeDriver to locate the driver executable.

2. Step 2: Identify consequence of wrong order

   Creating ChromeDriver before setting path causes runtime error as driver is not found.

3. Final Answer:

   System.setProperty must be called before creating ChromeDriver instance -> Option B

4. Quick Check:

   Set driver path before ChromeDriver creation [OK]

Hint: Always set driver path before new ChromeDriver() [OK]

Common Mistakes:

• Calling driver.get before setting driver path
• Using non-existent driver.setPath method
• Ignoring order of setup steps

5. You want to run multiple Selenium tests in parallel using ChromeDriver. Which setup practice helps avoid conflicts and resource leaks?

hard

A. Manually kill Chrome processes after all tests finish instead of driver.quit()

B. Use a single ChromeDriver instance shared by all tests without quitting

C. Set the ChromeDriver path only once at the start of all tests and never again

D. Create a new ChromeDriver instance for each test and call driver.quit() after each test

Solution

1. Step 1: Understand parallel test isolation

   Each test should have its own ChromeDriver instance to avoid interference.

2. Step 2: Importance of quitting driver

   Calling driver.quit() after each test frees resources and closes browser properly.

3. Final Answer:

   Create a new ChromeDriver instance for each test and call driver.quit() after each test -> Option D

4. Quick Check:

   Separate driver per test + quit to avoid conflicts [OK]

Hint: New driver per test + quit after test avoids conflicts [OK]

Common Mistakes:

• Sharing one driver instance across tests
• Not quitting driver causing resource leaks
• Relying on manual process killing
