Test estimation techniques in Testing Fundamentals - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to calculate the total test effort by multiplying the number of test cases by the average time per test case.

Testing Fundamentals

total_effort = num_test_cases [1] avg_time_per_test

💡 Hint

Common Mistakes

Using + instead of * results in incorrect total effort.

We multiply the number of test cases by the average time per test case to get the total effort.

2fill in blank

medium

Complete the code to estimate the number of test cases using the function points and a productivity factor.

Testing Fundamentals

estimated_tests = function_points [1] productivity_factor

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

💡 Hint

Common Mistakes

Using division or addition instead of multiplication.

Multiplying function points by productivity factor estimates the number of test cases.

3fill in blank

hard

Fix the error in the code to calculate the average time per test case by dividing total time by number of test cases.

Testing Fundamentals

avg_time = total_time [1] num_test_cases

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

💡 Hint

Common Mistakes

Using multiplication or addition instead of division.

Average time is total time divided by number of test cases.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that maps each test type to its estimated effort if the effort is greater than 5 hours.

Testing Fundamentals

effort_estimates = {test_type: [1] for test_type, [2] in test_data.items() if [1] > 5}

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

Ccount

💡 Hint

Common Mistakes

Using different variable names for value in comprehension and condition.

The dictionary maps test_type to effort, iterating over test_data items with effort as value.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps each test case ID (uppercased) to its duration if the duration is greater than 2 hours.

Testing Fundamentals

filtered_tests = {{ [1]: [2] for test_id, [3] in tests.items() if [2] > 2 }}

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

Atest_id.upper()

Bduration

Dtest_id

💡 Hint

Common Mistakes

Using test_id instead of uppercased test_id as key.

Mismatching variable names.

The comprehension uses uppercased test_id as key and duration as value, filtering by duration > 2.
