Performance test reporting in Testing Fundamentals - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to print the total time taken for the performance test.

Testing Fundamentals

print('Total test time:', [1], 'seconds')

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

Aelapsed_time

Btotal_time

Ctest_duration

Drun_time

Attempts:

3 left

💡 Hint

Common Mistakes

Using a variable name that does not exist or is unrelated to time.

The variable elapsed_time holds the total time taken for the test, so it should be printed.

2fill in blank

medium

Complete the code to calculate the average response time from the list of response times.

Testing Fundamentals

average_time = sum(response_times) [1] len(response_times)

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

A/

B*

C+

D-

Attempts:

3 left

💡 Hint

Common Mistakes

Using multiplication or addition instead of division.

To find the average, sum all response times and divide by the number of responses.

3fill in blank

hard

Fix the error in the assertion that checks if the maximum response time is below the threshold.

Testing Fundamentals

assert max(response_times) [1] threshold, 'Response time too high!'

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

A>=

B<=

C>

D<

Attempts:

3 left

💡 Hint

Common Mistakes

Using greater than or equal operators which invert the logic.

The assertion should confirm the max response time is less than the threshold, so use <.

4fill in blank

hard

Fill both blanks to create a dictionary of response times for each user where times are greater than 100ms.

Testing Fundamentals

slow_responses = {user: [1] for user, [2] in responses.items() if max(times) > 100}

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

Atimes

Btime

Ctimes_list

Dtime_list

Attempts:

3 left

💡 Hint

Common Mistakes

Using inconsistent variable names causing errors.

The dictionary comprehension uses times as the value and times as the variable for each user's response times.

5fill in blank

hard

Fill all three blanks to create a report dictionary with user names in uppercase, their average response time, and only include users with average below 200ms.

Testing Fundamentals

report = {user[1]: sum(times)[2]len(times) for user, times in data.items() if (sum(times)[3]len(times)) < 200}

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

A.upper()

B/

D.lower()

Attempts:

3 left

💡 Hint

Common Mistakes

Using .lower() instead of .upper().

Using multiplication or addition instead of division for average.

User names are converted to uppercase with .upper(). Average is sum divided by length using /. The filter uses the same division to check average below 200.
