Performance testing basics in Testing Fundamentals - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define the main goal of performance testing.

Testing Fundamentals

performance_goal = "Ensure the system [1] under expected load"

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

💡 Hint

Common Mistakes

Choosing options that describe poor performance like 'fails often' or 'runs slowly'.

The main goal of performance testing is to ensure the system responds quickly under expected load.

2fill in blank

medium

Complete the code to specify the type of test that measures system behavior under heavy load.

Testing Fundamentals

test_type = "[1] testing"

💡 Hint

Common Mistakes

Confusing load testing with unit or usability testing.

Load testing measures system behavior under heavy load.

3fill in blank

hard

Fix the error in the code to correctly calculate response time in milliseconds.

Testing Fundamentals

response_time_ms = response_time_seconds [1] 1000

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

C+

D/

💡 Hint

Common Mistakes

Using division or addition instead of multiplication.

To convert seconds to milliseconds, multiply by 1000.

4fill in blank

hard

Complete the code to create a dictionary comprehension that maps each user to their response time if it is less than 200 ms.

Testing Fundamentals

fast_responses = {user: response for user, response in responses.items() if response [1] 200}

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

B*

C<

D>

Attempts:

3 left

💡 Hint

Common Mistakes

Adding unnecessary operations on response value.

Using > instead of < for filtering.

The dictionary comprehension keeps the response as is (no operation), and filters responses less than 200 ms.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps each test name in uppercase to its average response time if the time is greater than 100 ms.

Testing Fundamentals

avg_times = {test[1]: time for test, time in test_results.items() if time [2] 100 and test[3].startswith('load')}

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

A.upper()

B>

C.lower()

D<

Attempts:

3 left

💡 Hint

Common Mistakes

Using .lower() instead of .upper() for the key.

Using < instead of > for time filter.

The test name is converted to uppercase for the key, the time is filtered to be greater than 100 ms, and the test name starts with 'load' in lowercase.
