06.05 Testing Unit Subsystem System And Quality Assurance - Quiz

Check your understanding

1. What is the primary purpose of unit testing in object-oriented programming?

   • To test the entire system from end to end
   • To test individual methods and classes in isolation { data-correct }
   • To test user interface components
   • To test database connections

2. Which characteristic is most important for a good unit test?

   • It should test multiple classes at once
   • It should connect to external databases
   • It should be independent and repeatable { data-correct }
   • It should take several minutes to run

3. In the Python unittest setUp method?framework, what is the purpose of the

   • To clean up after all tests are complete
   • To configure test fixtures before each test method runs { data-correct }
   • To run the actual test logic
   • To generate test reports

4. What type of testing focuses on verifying that different classes work correctly when combined?

   • Unit testing
   • System testing
   • Subsystem (integration) testing { data-correct }
   • Acceptance testing

5. Which assertion would be most appropriate to test that a method raises a specific exception?

   • self.assertEqual(exception, ValueError)
   • self.assertTrue(method_raises_error())
   • with self.assertRaises(ValueError): method_call() { data-correct }
   • self.assertIsNone(method_call())

6. What is the main focus of system testing?

   • Testing individual methods in isolation
   • Testing complete user workflows and business requirements { data-correct }
   • Testing only error conditions
   • Testing code performance and speed

7. In Test-Driven Development (TDD), when should you write the tests?

   • After implementing all the functionality
   • Before implementing the functionality { data-correct }
   • Only when bugs are discovered
   • At the end of the project

8. What should a good code review checklist for object-oriented code include?

   • Only syntax and formatting rules
   • Single responsibility, encapsulation, clear naming, and test coverage { data-correct }
   • Only performance optimization checks
   • Only documentation requirements

9. Which of the following best describes acceptance criteria?

   • Technical specifications for developers only
   • Performance benchmarks for system speed
   • Clear definitions of when features are considered complete and working { data-correct }
   • Documentation standards for code comments

10. What is the most important benefit of maintaining a continuous testing mindset?

    • It reduces the need for documentation
    • It catches problems early and builds confidence in code changes { data-correct }
    • It eliminates the need for code reviews
    • It makes development faster by skipping planning phases
