Stress testing concepts in Testing Fundamentals - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define stress testing as testing the system under {{BLANK_1}} load conditions.

Testing Fundamentals

stress_test_definition = "Stress testing is testing the system under [1] load conditions."

💡 Hint

Common Mistakes

Choosing 'normal' or 'average' load instead of extreme.

Stress testing checks how the system behaves under extreme load, beyond normal usage.

2fill in blank

medium

Complete the code to show that stress testing helps find {{BLANK_1}} that appear under heavy load.

Testing Fundamentals

def stress_testing_goal():
    return "Find [1] that appear under heavy load"

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

💡 Hint

Common Mistakes

Choosing 'features' or 'designs' which are unrelated to errors.

Stress testing aims to find bugs or errors that occur when the system is overloaded.

3fill in blank

hard

Fix the error in the code to correctly simulate a stress test by increasing the load to {{BLANK_1}} users.

Testing Fundamentals

def simulate_stress_test(current_users):
    load = current_users * [1]
    return load

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

💡 Hint

Common Mistakes

Using 1 or less which does not increase load.

Using negative numbers which are invalid.

Stress testing increases load significantly, so multiplying by 10 simulates heavy load.

4fill in blank

hard

Fill both blanks to create a test that runs until the system {{BLANK_1}} or the time {{BLANK_2}} out.

Testing Fundamentals

def run_stress_test():
    while not system.[1]() and not timer.[2]():
        system.increase_load()

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

Bstarts

Ctimes_out

Dresets

💡 Hint

Common Mistakes

Using 'starts' or 'resets' which do not indicate stopping conditions.

The test runs until the system fails or the timer times_out.

5fill in blank

hard

Fill all three blanks to create a report dictionary with keys for {{BLANK_1}}, {{BLANK_2}}, and {{BLANK_3}} after stress testing.

Testing Fundamentals

report = {
    '[1]': system.status(),
    '[2]': test.duration(),
    '[3]': test.errors()
}

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

Astatus

Bduration

Cerrors

Dusers

💡 Hint

Common Mistakes

Including 'users' which is not part of this report.

The report includes status, duration, and errors keys to summarize the stress test.
