Complete the code to add the argument to start Edge in headless mode.

Selenium Java

options.addArguments([1]);

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

A"--disable-gpu"

B"--headless"

C"--start-maximized"

D"--incognito"

Attempts:

3 left

💡 Hint

Common Mistakes

Using "--disable-gpu" which disables GPU but does not make browser headless.

Using "--start-maximized" which opens browser maximized but visible.

The "--headless" argument runs Edge without opening a visible window.

3fill in blank

Fix the error in setting the binary path for Edge browser.

Selenium Java

options.setBinary([1]);

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

Anew File("C:/Program Files/Microsoft/Edge/Application/msedge.exe")

BPaths.get("C:/Program Files/Microsoft/Edge/Application/msedge.exe")

C"C:/Program Files/Microsoft/Edge/Application/msedge.exe"

DPath.of("C:/Program Files/Microsoft/Edge/Application/msedge.exe")

Attempts:

3 left

💡 Hint

Common Mistakes

Passing a File object instead of a String.

Passing a Path object which causes a type mismatch.

The setBinary method expects a String path, not a File or Path object.

4fill in blank

hard

Fill both blanks to set EdgeOptions to accept insecure certificates and disable extensions.

Selenium Java

options.setAcceptInsecureCerts([1]);
options.addArguments([2]);

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

Atrue

B"--disable-extensions"

Cfalse

D"--enable-automation"

Attempts:

3 left

💡 Hint

Common Mistakes

Using false for accepting insecure certificates disables this feature.

Using wrong argument strings that do not disable extensions.

Setting setAcceptInsecureCerts(true) allows insecure SSL certificates.
Adding "--disable-extensions" disables browser extensions.

5fill in blank

hard

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

Selenium Java

options.addArguments([1]);
options.addArguments([2]);
options.addArguments([3]);

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

A"--headless"

B"--window-size=1920,1080"

C"--disable-gpu"

D"--incognito"

Attempts:

3 left

💡 Hint

Common Mistakes

Forgetting to disable GPU which can cause issues in headless mode.

Using incorrect window size format.

These arguments configure Edge to run headless, set the window size, and disable GPU usage for better compatibility.

Practice

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

easy

A. To customize Microsoft Edge browser settings before launching it

B. To write test assertions for Edge browser

C. To locate web elements on the Edge browser page

D. To generate test reports for Edge browser tests

Solution

1. Step 1: Understand EdgeOptions role

   EdgeOptions is used to set browser preferences and configurations before starting Edge.

2. Step 2: Differentiate from other test tasks

   Assertions, locating elements, and reporting are separate tasks not handled by EdgeOptions.

3. Final Answer:

   To customize Microsoft Edge browser settings before launching it -> Option A

4. Quick Check:

   EdgeOptions = browser setup [OK]

Hint: EdgeOptions sets browser settings before launch [OK]

Common Mistakes:

• Confusing EdgeOptions with assertion or locator classes
• Thinking EdgeOptions generates reports
• Using EdgeOptions to find elements

2. Which of the following is the correct way to add the argument --headless to an EdgeOptions object in Java?

easy

A. options.addArguments("--headless");

B. options.setArguments("--headless");

C. options.addArgument("headless");

D. options.setCapability("headless", true);

Solution

1. Step 1: Recall method to add arguments

   The correct method to add command-line arguments is addArguments(String... args).

2. Step 2: Check argument format

   The argument must be "--headless" with two dashes, matching browser flags.

3. Final Answer:

   options.addArguments("--headless"); -> Option A

4. Quick Check:

   Use addArguments("--headless") [OK]

Hint: Use addArguments with double dashes for flags [OK]

Common Mistakes:

• Using setArguments instead of addArguments
• Missing dashes in argument string
• Confusing addArgument (singular) which doesn't exist

3. Given the following code snippet, what will be the effect on the Edge browser when launched?

EdgeOptions options = new EdgeOptions();
options.addArguments("--disable-gpu");
options.setCapability("acceptInsecureCerts", true);
EdgeDriver driver = new EdgeDriver(options);

medium

A. The browser runs with GPU enabled and rejects insecure certificates

B. The browser runs in headless mode and blocks insecure certificates

C. The browser disables GPU hardware acceleration and accepts insecure SSL certificates

D. The browser disables GPU and runs with default SSL certificate settings

Solution

1. Step 1: Analyze addArguments call

   Adding "--disable-gpu" disables GPU hardware acceleration in Edge.

2. Step 2: Analyze setCapability call

   Setting "acceptInsecureCerts" to true allows the browser to accept insecure SSL certificates.

3. Final Answer:

   The browser disables GPU hardware acceleration and accepts insecure SSL certificates -> Option C

4. Quick Check:

   Disable GPU + accept insecure certs = The browser disables GPU hardware acceleration and accepts insecure SSL certificates [OK]

Hint: Check argument effects and capability flags carefully [OK]

Common Mistakes:

• Confusing headless mode with disable-gpu
• Assuming default SSL behavior without checking capability
• Ignoring the effect of setCapability on SSL

4. Identify the error in the following EdgeOptions configuration code:

EdgeOptions options = new EdgeOptions();
options.addArguments("headless");
options.setCapability("acceptInsecureCerts", "true");
EdgeDriver driver = new EdgeDriver(options);

medium

A. addArguments should be replaced with setArguments and acceptInsecureCerts is correct

B. The argument "headless" is missing dashes and acceptInsecureCerts should be boolean, not string

C. EdgeOptions cannot set capabilities, use DesiredCapabilities instead

D. No error, code will run correctly

Solution

1. Step 1: Check argument format

   "headless" argument must be "--headless" with two dashes to work properly.

2. Step 2: Check capability value type

   "acceptInsecureCerts" expects a boolean value, not a string "true".

3. Final Answer:

   The argument "headless" is missing dashes and acceptInsecureCerts should be boolean, not string -> Option B

4. Quick Check:

   Arguments need dashes + boolean capability [OK]

Hint: Arguments need dashes; booleans not strings for capabilities [OK]

Common Mistakes:

• Using string "true" instead of boolean true
• Missing dashes in command-line arguments
• Thinking setArguments exists instead of addArguments

5. You want to configure EdgeOptions to run tests in headless mode, disable extensions, and accept insecure certificates. Which code snippet correctly achieves this?

hard

A. EdgeOptions options = new EdgeOptions();
options.addArguments("--headless");
options.addArguments("disable-extensions");
options.setCapability("acceptInsecureCerts", false);

B. EdgeOptions options = new EdgeOptions();
options.addArguments("headless", "disable-extensions");
options.setCapability("acceptInsecureCerts", "true");

C. EdgeOptions options = new EdgeOptions();
options.setArguments("--headless", "--disable-extensions");
options.setCapability("acceptInsecureCerts", true);

D. EdgeOptions options = new EdgeOptions();
options.addArguments("--headless", "--disable-extensions");
options.setCapability("acceptInsecureCerts", true);

Solution

1. Step 1: Verify argument syntax

   Arguments must have double dashes and be passed correctly. EdgeOptions options = new EdgeOptions(); options.addArguments("--headless", "--disable-extensions"); options.setCapability("acceptInsecureCerts", true); uses "--headless" and "--disable-extensions" properly.

2. Step 2: Check capability for insecure certs

   Capability "acceptInsecureCerts" must be boolean true to accept insecure certificates, as in EdgeOptions options = new EdgeOptions(); options.addArguments("--headless", "--disable-extensions"); options.setCapability("acceptInsecureCerts", true);.

3. Step 3: Confirm no syntax errors

   EdgeOptions options = new EdgeOptions(); options.addArguments("--headless", "--disable-extensions"); options.setCapability("acceptInsecureCerts", true); uses correct methods and types; others have missing dashes, wrong method names, or wrong boolean values.

4. Final Answer:

   EdgeOptions options = new EdgeOptions(); options.addArguments("--headless", "--disable-extensions"); options.setCapability("acceptInsecureCerts", true); -> Option D

5. Quick Check:

   Correct args + boolean capability = EdgeOptions options = new EdgeOptions(); options.addArguments("--headless", "--disable-extensions"); options.setCapability("acceptInsecureCerts", true); [OK]

Hint: Use addArguments with dashes and boolean for capabilities [OK]

Common Mistakes:

• Missing dashes in arguments
• Passing string instead of boolean for capabilities
• Using non-existent setArguments method
