Challenge - 5 Problems

🧠 Conceptual

How do testing approaches influence test planning?

Which statement best explains why choosing a testing approach is important for planning test activities?

A Because the approach fixes all bugs automatically without manual effort.

B Because the approach decides the programming language used for the software.

C Because the approach determines the hardware requirements for the software.

D Because the approach defines what types of tests to run and when to run them during development.

💡 Hint

Think about how testing fits into the software development timeline.

Testing approaches guide the selection and timing of tests, helping teams plan what to test and when, ensuring effective coverage.

❓ Predict Output

Output of test result aggregation

Given the following test results collected using a specific testing approach, what is the final test status?

Testing Fundamentals

test_results = ['pass', 'fail', 'pass', 'pass']
final_status = 'pass' if 'fail' not in test_results else 'fail'
print(final_status)

A pass

B fail

C error

D unknown

💡 Hint

Check if any test failed in the list.

The code sets final_status to 'fail' if any test result is 'fail'. Since there is one 'fail', the output is 'fail'.

❓ assertion

Correct assertion for verifying test coverage

Which assertion correctly checks that all required test cases have been executed?

Testing Fundamentals

executed_tests = {'login', 'signup', 'logout'}
required_tests = {'login', 'signup', 'logout', 'profile_update'}

A assert executed_tests <= required_tests

B assert executed_tests >= required_tests

C assert executed_tests == required_tests

D assert executed_tests != required_tests

💡 Hint

Think about subset and superset relations.

executed_tests <= required_tests checks if executed_tests is a subset of required_tests, meaning all executed tests are required tests. To verify that all required tests have been executed, executed_tests should be a superset of required_tests (executed_tests >= required_tests). Since executed_tests is missing 'profile_update', the correct assertion to check if all required tests have been executed is executed_tests >= required_tests, but given the sets, the assertion that correctly checks that all required tests have been executed is assert executed_tests >= required_tests. However, the sets show executed_tests is missing 'profile_update', so the assertion should fail. The correct answer is B to check if all required tests have been executed.

Identify the error in test case selection code

What error will this code cause when selecting test cases based on priority?

Testing Fundamentals

test_cases = [{'id': 1, 'priority': 'high'}, {'id': 2, 'priority': 'low'}]
high_priority = [tc for tc in test_cases if tc.priority == 'high']
print(high_priority)

A AttributeError because dictionary keys should be accessed with brackets, not dot notation.

B SyntaxError due to missing colon in list comprehension.

C TypeError because test_cases is not iterable.

D No error; prints high priority test cases.

💡 Hint

Check how dictionary elements are accessed in Python.

Dictionary keys must be accessed with brackets like tc['priority'], not dot notation tc.priority, which causes AttributeError.

Choosing the best testing approach for continuous integration

Which testing approach best supports fast feedback in a continuous integration (CI) environment?

A Ad-hoc testing without documentation.

B Manual exploratory testing after each deployment.

C Automated unit testing with parallel execution.

D Full regression testing manually before release.

💡 Hint

Consider speed and automation in CI pipelines.

Automated unit tests run quickly and in parallel, providing fast feedback essential for CI. Manual or ad-hoc tests are slower and less reliable for CI.
