Test metrics and KPIs in Testing Fundamentals - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to calculate the defect density.

Testing Fundamentals

defect_density = total_defects / [1]

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

💡 Hint

Common Mistakes

Using total_test_cases instead of total_lines_of_code.

Defect density is calculated as the number of defects divided by the total lines of code.

2fill in blank

medium

Complete the code to calculate test execution progress percentage.

Testing Fundamentals

progress = (executed_tests / [1]) * 100

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

Atotal_tests

Bpassed_tests

Cfailed_tests

Dblocked_tests

Attempts:

💡 Hint

Common Mistakes

Using passed_tests or failed_tests instead of total_tests.

Progress is the ratio of executed tests to total tests, multiplied by 100 for percentage.

3fill in blank

hard

Fix the error in the code to calculate test pass rate.

Testing Fundamentals

pass_rate = (passed_tests / [1]) * 100

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

Ablocked_tests

Btotal_tests

Cfailed_tests

Dexecuted_tests

💡 Hint

Common Mistakes

Using total_tests instead of executed_tests causes incorrect pass rate.

Pass rate is the percentage of passed tests out of executed tests, not total tests.

4fill in blank

hard

Fill both blanks to calculate defect removal efficiency.

Testing Fundamentals

defect_removal_efficiency = (defects_found_in_testing / [1]) * [2]

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

Atotal_defects

B100

Ctotal_test_cases

Dexecuted_tests

Attempts:

3 left

💡 Hint

Common Mistakes

Using total_test_cases or executed_tests instead of total_defects.

Defect removal efficiency is defects found in testing divided by total defects, multiplied by 100 for percentage.

5fill in blank

hard

Fill all three blanks to create a dictionary of test metrics with conditions.

Testing Fundamentals

metrics = {test + [1]: result for test, result in test_results.items() if result [2] [3]

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

A_id

B==

C'pass'

D!=

💡 Hint

Common Mistakes

Using '!=' instead of '==' causes wrong filtering.

This dictionary comprehension creates a dictionary of test IDs and results only for tests that passed.
