Why does automation reduce test execution time?

Imagine you have to check 100 doors to see if they lock properly. Doing it by hand takes a long time. How does automation help in this situation?

A Automation runs tests faster by repeating steps without breaks, saving time compared to manual checks.

B Automation makes tests slower because setting up machines takes longer than manual work.

C Automation only helps if tests are done once; repeating tests manually is faster.

D Automation replaces testers completely, so no one needs to check the doors anymore.

💡 Hint

Think about how machines can work continuously without getting tired.

Automation speeds up testing by running repetitive tasks quickly and without breaks, unlike humans who need rest.

Output of automated test run time calculation

What is the output of this Python code that simulates test execution times?

Testing Fundamentals

test_cases = 50
manual_time_per_test = 2  # minutes
automation_time_per_test = 0.5  # minutes
setup_time = 10  # minutes
manual_total = test_cases * manual_time_per_test
automation_total = setup_time + (test_cases * automation_time_per_test)
print(f"Manual: {manual_total} min, Automation: {automation_total} min")

A Manual: 50 min, Automation: 35.0 min

B Manual: 50 min, Automation: 25.0 min

C Manual: 100 min, Automation: 35.0 min

D Manual: 100 min, Automation: 25.0 min

💡 Hint

Calculate total time for manual and automation separately.

Manual total is 50 tests * 2 min = 100 min. Automation total is 10 min setup + 50 * 0.5 min = 35 min.

❓ assertion

Correct assertion for automation speed test

You want to check if automated tests run faster than manual tests. Which assertion correctly tests this?

Testing Fundamentals

manual_time = 120  # seconds
automation_time = 45  # seconds
# Choose the correct assertion below:

A assert manual_time < 0

B assert automation_time > manual_time

C assert automation_time == manual_time

D assert automation_time < manual_time

💡 Hint

Automation should be faster, so its time is less.

The assertion checks that automation_time is less than manual_time, confirming automation is faster.

🔧 Debug

Find the bug in this automation timing code

What error will this code produce when calculating total automation time?

Testing Fundamentals

test_cases = 30
setup_time = 5
automation_time_per_test = '0.5'
total_time = setup_time + (test_cases * automation_time_per_test)
print(total_time)

A SyntaxError due to missing colon

B TypeError because you cannot multiply int by str

C NameError because variable is undefined

D Prints 20.0 without error

💡 Hint

Check the data types used in multiplication.

Multiplying an integer by a string causes a TypeError in Python.

❓ framework

Best practice for integrating automation in CI/CD pipelines

Which option describes the best way to accelerate testing using automation in a Continuous Integration/Continuous Deployment (CI/CD) pipeline?

A Run automated tests automatically on every code change to catch issues early and speed up feedback.

B Run automated tests only once a month to save computing resources.

C Run manual tests first, then run automation only if manual tests fail.

D Skip automated tests and rely on manual testing to ensure quality.

💡 Hint

Think about how fast feedback helps developers fix problems quickly.

Running automated tests on every code change helps find bugs early and speeds up the release process.
