Edge configuration in Selenium Python - Practice Problems & Coding Challenges

Challenge - 5 Problems

❓ Predict Output

What is the output of this Edge WebDriver configuration code?

Consider the following Python Selenium code snippet configuring Edge WebDriver. What will be printed when this code runs successfully?

Selenium Python

from selenium import webdriver
from selenium.webdriver.edge.options import Options

options = Options()
options.use_chromium = True
options.add_argument('--headless')
options.add_argument('--disable-gpu')

driver = webdriver.Edge(options=options)
print(driver.capabilities['browserName'])
driver.quit()

A "chrome"

B "edge"

C "firefox"

D "safari"

💡 Hint

Check the browserName capability for Edge when using Chromium-based EdgeDriver.

The Edge WebDriver when configured with Chromium options reports the browserName as "edge" in capabilities.

❓ locator

intermediate

Which locator strategy is best for stable Edge WebDriver tests?

You want to locate a button with text "Submit" on a webpage using Edge WebDriver. Which locator is the most stable and recommended?

A driver.find_element('id', "submit")

B driver.find_element('css selector', "button.submit-btn")

C driver.find_element('xpath', "//button[text()='Submit']")

D driver.find_element('class name', "btn")

💡 Hint

IDs are unique and less likely to change compared to classes or text.

Using 'id' is the most stable locator because IDs are unique and less prone to change, making tests more reliable.

❓ assertion

advanced

Which assertion correctly verifies Edge browser is running in headless mode?

Given an Edge WebDriver instance configured with headless mode, which assertion correctly checks this setting?

Selenium Python

from selenium import webdriver
from selenium.webdriver.edge.options import Options

options = Options()
options.add_argument('--headless')
driver = webdriver.Edge(options=options)

A assert '--headless' in driver.capabilities['ms:edgeOptions']['args']

B assert 'headless' in driver.capabilities['browserName']

C assert driver.capabilities['headless'] == True

D assert driver.execute_script('return navigator.webdriver') == False

💡 Hint

Check the Edge-specific options in capabilities for the headless argument.

The headless argument is stored in 'ms:edgeOptions' under 'args' in capabilities, so checking for '--headless' there is correct.

🔧 Debug

Why does this Edge WebDriver code raise a SessionNotCreatedException?

Review the code below. Why does it raise a SessionNotCreatedException when run?

Selenium Python

from selenium import webdriver
from selenium.webdriver.edge.options import Options

options = Options()
options.use_chromium = False

driver = webdriver.Edge(options=options)
driver.quit()

A Because the Edge browser is not installed on the system

B Because Edge WebDriver does not support options parameter

C Because use_chromium is set to False but the installed EdgeDriver only supports Chromium-based Edge

D Because options object is missing required arguments for Edge

💡 Hint

Check compatibility between EdgeDriver and browser versions regarding Chromium usage.

Setting use_chromium to False tries to start legacy Edge, but modern EdgeDriver supports only Chromium-based Edge, causing SessionNotCreatedException.

How to configure pytest to run tests only on Edge with headless mode?

You want to run Selenium tests using pytest only on Edge browser in headless mode. Which pytest fixture configuration is correct?

Selenium Python

import pytest
from selenium import webdriver
from selenium.webdriver.edge.options import Options

@pytest.fixture
 def driver():
  options = Options()
  options.add_argument('--headless')
  driver = webdriver.Edge(options=options)
  yield driver
  driver.quit()

A

@pytest.fixture
 def driver():
  options = Options()
  options.add_argument('--disable-gpu')
  driver = webdriver.Edge(options=options)
  yield driver
  driver.quit()

B

@pytest.fixture
 def driver():
  options = Options()
  options.use_chromium = False
  driver = webdriver.Edge(options=options)
  yield driver
  driver.quit()

C

@pytest.fixture
 def driver():
  driver = webdriver.Edge()
  yield driver
  driver.quit()

D

@pytest.fixture
 def driver():
  options = Options()
  options.add_argument('--headless')
  driver = webdriver.Edge(options=options)
  yield driver
  driver.quit()

💡 Hint

Headless mode requires adding the '--headless' argument to Edge options.

Option D correctly adds '--headless' argument to Edge options and uses a pytest fixture to manage driver lifecycle.
