easy

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

Testing Fundamentals

def load_testing_goal():
    return "To measure system performance under [1] load"

💡 Hint

Common Mistakes

Choosing 'normal' load instead of 'heavy' load.

Load testing aims to measure how a system performs under heavy load, simulating many users or transactions.

Complete the code to specify the tool commonly used for load testing.

    return "[1]"

💡 Hint

Common Mistakes

Confusing JMeter with Selenium or Postman.

Apache JMeter is a popular open-source tool used for load testing web applications.

Fix the error in the code that sets the number of virtual users for load testing.

Testing Fundamentals

virtual_users = [1]  # Number of users to simulate

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

B10

Cuser_count

DNone

💡 Hint

Common Mistakes

Using a string like 'ten' instead of number 10.

The number of virtual users must be an integer, so 10 is correct. Using a string or None will cause errors.

4fill in blank

hard

Fill both blanks to create a dictionary that stores response times for each user during load testing.

Testing Fundamentals

response_times = {user[1]: [2] for user in range(1, 6)}

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

A_id

Bget_response_time(user)

Cuser

Duser + 1

💡 Hint

Common Mistakes

Using 'user' as key without '_id', or using 'user' as value instead of response time.

The key should be 'user_id' to identify each user, and the value should be the response time from a function call.

5fill in blank

hard

Fill all three blanks to filter response times greater than 200 ms and create a summary dictionary.

Testing Fundamentals

slow_responses = {user[1]: time for user, time in response_times.items() if time [2] [3]

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

D<

💡 Hint

Common Mistakes

Using '<' instead of '>' or wrong key name.

We use 'user_id' as key, filter times greater than (>) 200 milliseconds to find slow responses.
