Complete the code to start a Selenium WebDriver for Chrome.

Selenium Python

driver = webdriver.[1]()

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

AFirefox

BEdge

CSafari

DChrome

3 left

💡 Hint

Common Mistakes

Using Firefox instead of Chrome when Chrome is required.

The correct method to start a Chrome browser in Selenium is webdriver.Chrome().

Complete the code to check if the page title contains the word 'Home'.

Selenium Python

assert 'Home' [1] driver.title

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

💡 Hint

Common Mistakes

Using '==' which checks for exact match instead of containment.

To check if 'Home' is part of the page title, use the in keyword.

Fix the error in the code to wait until an element with id 'submit' is clickable.

Selenium Python

WebDriverWait(driver, 10).until(EC.[1]((By.ID, 'submit')))

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

Apresence_of_element_located

Bvisibility_of_element_located

Celement_to_be_clickable

Dalert_is_present

Attempts:

💡 Hint

Common Mistakes

Using presence_of_element_located which only checks if element is in DOM.

The correct expected condition to wait for a clickable element is element_to_be_clickable.

Fill both blanks to create a test function that uses pytest and asserts page title.

Selenium Python

def test_title(driver):
    driver.get('http://example.com')
    assert [1] [2] 'Example Domain'

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

Adriver.title

Attempts:

💡 Hint

Common Mistakes

Using 'in' instead of '==' when exact match is needed.

The test checks if the page title exactly equals 'Example Domain' using driver.title == 'Example Domain'.

5fill in blank

hard

Fill all three blanks to define a pytest fixture that initializes and quits the WebDriver.

Selenium Python

import pytest

@pytest.fixture
 def driver():
    driver = webdriver.[1]()
    yield [2]
    [3].quit()

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

AChrome

Bdriver

DFirefox

💡 Hint

Common Mistakes

Using different variable names inconsistently.

The fixture starts a Chrome WebDriver, yields it for tests, then quits it after tests finish.

Practice

1. What is the main benefit of integrating Selenium tests with a Continuous Integration (CI) system?

easy

A. Tests run slower because of extra CI overhead

B. Tests run only when manually triggered by developers

C. Tests run automatically on every code change, catching bugs early

D. Tests require manual approval before running

Solution

1. Step 1: Understand CI integration purpose

   CI systems automatically run tests whenever code changes are pushed.

2. Step 2: Identify benefit of automatic test runs

   This automation helps catch bugs early without manual effort.

3. Final Answer:

   Tests run automatically on every code change, catching bugs early -> Option C

4. Quick Check:

   CI auto-runs tests = Early bug detection [OK]

Hint: CI runs tests on code changes automatically [OK]

Common Mistakes:

• Thinking tests run only manually
• Assuming CI slows down tests
• Believing manual approval is needed

2. Which of the following is the correct way to trigger Selenium tests in a CI pipeline using Python?

easy

A. Add sleep(10) to delay tests

B. Manually open browser and run tests

C. Use print('run tests') in the test file

D. Run pytest tests/ command in the CI script

Solution

1. Step 1: Identify how tests run in CI

   CI pipelines run commands like pytest tests/ to execute tests automatically.

2. Step 2: Evaluate options for triggering tests

   Manual browser opening or print statements do not trigger automated CI tests.

3. Final Answer:

   Run pytest tests/ command in the CI script -> Option D

4. Quick Check:

   CI runs test commands like pytest [OK]

Hint: CI runs shell commands to execute tests [OK]

Common Mistakes:

• Confusing manual test runs with CI automation
• Using print statements expecting test execution
• Adding delays instead of running tests

3. Given this CI pipeline snippet running Selenium tests:

steps:
  - name: Run tests
    run: pytest tests/

What is the expected outcome when a test fails?

medium

A. The CI pipeline stops and reports failure immediately

B. The pipeline ignores failures and continues

C. The tests rerun automatically until they pass

D. The pipeline deletes the test files

Solution

1. Step 1: Understand CI pipeline behavior on test failure

   When a test fails, the pytest command returns a failure code, causing the CI pipeline to stop and report failure.

2. Step 2: Check other options for correctness

   CI does not ignore failures, rerun tests automatically, or delete files on failure.

3. Final Answer:

   The CI pipeline stops and reports failure immediately -> Option A

4. Quick Check:

   Test fail = CI fail and stop [OK]

Hint: Failed tests cause CI to stop and report failure [OK]

Common Mistakes:

• Thinking CI ignores test failures
• Assuming tests rerun automatically without config
• Believing CI deletes files on failure

4. You added Selenium tests to your CI pipeline, but tests never run after code pushes. What is the most likely cause?

medium

A. The tests are written in Python instead of Java

B. The CI configuration file does not include the test run command

C. The Selenium WebDriver is not installed on the developer's machine

D. The browser is not open on the developer's local computer

Solution

1. Step 1: Check CI configuration for test commands

   If the CI config file lacks the command to run tests, tests won't execute on code pushes.

2. Step 2: Evaluate other options

   Test language, developer machine setup, or local browser state do not affect CI test runs on the server.

3. Final Answer:

   The CI configuration file does not include the test run command -> Option B

4. Quick Check:

   Missing test command in CI config = no tests run [OK]

Hint: Check CI config includes test run command [OK]

Common Mistakes:

• Blaming test language instead of CI config
• Assuming local machine affects CI server runs
• Thinking browser must be open locally for CI

5. How does integrating Selenium tests with CI pipelines improve software release quality?

hard

A. By running automated tests on every code change, catching bugs early and ensuring reliability

B. By requiring manual test approval before each release

C. By delaying test runs until after software is released

D. By running tests only on developer machines

Solution

1. Step 1: Understand CI and Selenium integration benefits

   Automated tests run on every code change in CI, catching bugs early and preventing faulty code from releasing.

2. Step 2: Compare with other options

   Manual approvals, delayed tests, or local-only tests do not improve release quality as effectively.

3. Final Answer:

   By running automated tests on every code change, catching bugs early and ensuring reliability -> Option A

4. Quick Check:

   CI + Selenium = Early bug catch & reliable releases [OK]

Hint: CI auto-tests catch bugs early, improving release quality [OK]

Common Mistakes:

• Thinking manual approval improves quality more
• Believing tests run after release
• Assuming tests only run locally
