💡 Hint

Common Mistakes

Using setPreference which does not exist.

Using disableAutomationExtension which is not a preference key.

To disable the automation extension info bar, set the useAutomationExtension preference to false, then use setExperimentalOption to apply it.

5fill in blank

Fill all three blanks to create ChromeOptions with headless mode, disable GPU, and set window size.

Selenium Java

options.[1]("--headless");
options.[2]("--disable-gpu");
options.[3]("--window-size=1920,1080");

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

💡 Hint

Common Mistakes

Using setArguments which does not exist.

Using addArgument (singular) which is incorrect.

The method to add command-line arguments is addArguments. The correct calls are to add headless, disable GPU, and set window size arguments.

Practice

1. What is the primary purpose of using ChromeOptions in Selenium Java?

easy

A. To locate elements on a web page

B. To write test assertions for Chrome browser

C. To customize Chrome browser settings before launching it

D. To manage test data inputs

Solution

1. Step 1: Understand ChromeOptions role

   ChromeOptions is used to set browser preferences like headless mode or window size before starting Chrome.

2. Step 2: Differentiate from other Selenium tasks

   It is not used for assertions, locating elements, or managing test data, which are separate concerns.

3. Final Answer:

   To customize Chrome browser settings before launching it -> Option C

4. Quick Check:

   ChromeOptions = browser customization [OK]

Hint: ChromeOptions sets browser behavior before launch [OK]

Common Mistakes:

• Confusing ChromeOptions with element locators
• Thinking ChromeOptions handles test assertions
• Assuming ChromeOptions manages test data

2. Which of the following is the correct way to add the argument to start Chrome maximized using ChromeOptions in Java?

easy

A. options.addArguments("--start-maximized");

B. options.addArgument("start-maximized");

C. options.setArguments("--start-maximized");

D. options.addArguments("startMaximized");

Solution

1. Step 1: Recall correct method name

   The method to add arguments is addArguments (plural), not addArgument or setArguments.

2. Step 2: Use correct argument format

   Arguments must start with double dashes, so "--start-maximized" is correct.

3. Final Answer:

   options.addArguments("--start-maximized"); -> Option A

4. Quick Check:

   Method = addArguments, Argument = "--start-maximized" [OK]

Hint: Use addArguments("--option") with double dashes [OK]

Common Mistakes:

• Using singular addArgument instead of addArguments
• Omitting double dashes in argument string
• Using incorrect method setArguments

3. Given the following code snippet, what will be the effect when launching Chrome?

ChromeOptions options = new ChromeOptions();
options.addArguments("--headless");
options.addArguments("--disable-gpu");
ChromeDriver driver = new ChromeDriver(options);

medium

A. Chrome will launch in normal mode with GPU enabled

B. Chrome will launch maximized but not headless

C. Chrome will throw a syntax error due to addArguments usage

D. Chrome will launch in headless mode with GPU disabled

Solution

1. Step 1: Analyze added arguments

   The arguments "--headless" and "--disable-gpu" tell Chrome to run without UI and disable GPU acceleration.

2. Step 2: Understand ChromeDriver initialization

   Passing options to ChromeDriver applies these settings, so Chrome runs headless with GPU disabled.

3. Final Answer:

   Chrome will launch in headless mode with GPU disabled -> Option D

4. Quick Check:

   Arguments = headless + disable GPU [OK]

Hint: Headless mode needs "--headless" argument [OK]

Common Mistakes:

• Thinking addArguments causes syntax error
• Assuming headless mode still shows UI
• Ignoring GPU disable argument effect

4. Identify the error in the following code snippet that configures ChromeOptions:

ChromeOptions options = new ChromeOptions();
options.addArguments("start-maximized");
ChromeDriver driver = new ChromeDriver(options);

medium

A. Missing double dashes before argument "start-maximized"

B. Incorrect method name; should be addArgument instead of addArguments

C. ChromeOptions cannot be passed to ChromeDriver constructor

D. No error; code is correct

Solution

1. Step 1: Check argument format

   The argument "start-maximized" lacks the required "--" prefix for Chrome options.

2. Step 2: Verify method and usage

   The method addArguments is correct and ChromeOptions can be passed to ChromeDriver constructor, so no error there.

3. Final Answer:

   Missing double dashes before argument "start-maximized" -> Option A

4. Quick Check:

   Arguments need "--" prefix [OK]

Hint: Chrome arguments always start with "--" [OK]

Common Mistakes:

• Omitting double dashes in argument strings
• Confusing addArguments with addArgument
• Thinking ChromeOptions can't be passed to ChromeDriver

5. You want to launch Chrome in headless mode, disable extensions, and start maximized using ChromeOptions. Which code snippet correctly applies all these settings?

hard

A. ChromeOptions options = new ChromeOptions();
options.addArgument("--headless", "--disable-extensions", "--start-maximized");
ChromeDriver driver = new ChromeDriver(options);

B. ChromeOptions options = new ChromeOptions();
options.addArguments("--headless");
options.addArguments("--disable-extensions");
options.addArguments("--start-maximized");
ChromeDriver driver = new ChromeDriver(options);

C. ChromeOptions options = new ChromeOptions();
options.addArguments("headless");
options.addArguments("disable-extensions");
options.addArguments("start-maximized");
ChromeDriver driver = new ChromeDriver(options);

D. ChromeOptions options = new ChromeOptions();
options.setArguments(List.of("--headless", "--disable-extensions", "--start-maximized"));
ChromeDriver driver = new ChromeDriver(options);

Solution

1. Step 1: Identify required arguments

   The settings require "--headless", "--disable-extensions", and "--start-maximized", all prefixed with "--".

2. Step 2: Confirm correct method

   Use addArguments() (plural); invalid methods like addArgument() or setArguments() cause errors.

3. Step 3: Validate implementation

   Correct code applies each argument via separate addArguments calls.

4. Final Answer:

   ChromeOptions options = new ChromeOptions(); options.addArguments("--headless"); options.addArguments("--disable-extensions"); options.addArguments("--start-maximized"); ChromeDriver driver = new ChromeDriver(options); -> Option B

5. Quick Check:

   addArguments("--headless"), addArguments("--disable-extensions"), addArguments("--start-maximized") [OK]

Hint: Call addArguments separately with "--" prefixed options [OK]

Common Mistakes:

• Passing arguments without "--" prefix
• Using addArgument instead of addArguments
• Using non-existent setArguments method
