06.06 Test Strategies Black White Grey Box - Quiz

Check your understanding

1. What is the main characteristic of black box testing?

   • Tests are designed by examining the internal code structure
   • Tests are designed based on specifications without knowing internal implementation { data-correct }
   • Tests require partial knowledge of the system architecture
   • Tests focus only on error conditions

2. Which testing technique is most commonly used in black box testing to test boundary conditions?

   • Statement coverage analysis
   • Path coverage analysis
   • Boundary value analysis { data-correct }
   • Code inspection

3. What is the primary goal of white box testing?

   • To verify that the system meets user requirements
   • To ensure all code paths, statements, and conditions are tested { data-correct }
   • To test the system from an external user perspective
   • To validate business logic without seeing code

4. In equivalence partitioning, what principle guides the selection of test cases?

   • Test every possible input value
   • Test only boundary values
   • Test representative values from each group of inputs that should behave similarly { data-correct }
   • Test only the most complex scenarios

5. When would grey box testing be most appropriate?

   • When testing individual methods in isolation
   • When testing system integration with some knowledge of internal architecture { data-correct }
   • When testing without any knowledge of the system
   • When testing only user interface components

6. Which of the following is a white box testing technique?

   • Equivalence partitioning
   • Boundary value analysis
   • Statement coverage analysis { data-correct }
   • User acceptance testing

7. For a password validation function with the requirement “8-20 characters, at least one uppercase, one lowercase, one digit”, which represents the best black box test approach?

   • Test only with valid passwords
   • Test boundary conditions for length and character requirements { data-correct }
   • Examine the validation code and test all conditional branches
   • Test only the most common password patterns

8. What advantage does white box testing provide over black box testing?

   • It ensures the system meets user requirements
   • It can identify untested code paths and dead code { data-correct }
   • It tests the system from a user perspective
   • It requires less technical knowledge

9. In the context of testing an e-commerce checkout process, what would be a grey box testing approach?

   • Testing only the user interface workflow
   • Testing all internal database queries and transactions
   • Testing payment processing with knowledge of the security mechanisms used { data-correct }
   • Testing without any knowledge of the system architecture

10. Which testing strategy would be most effective for ensuring that all conditional statements in a complex algorithm are properly tested?

    • Black box testing with equivalence partitioning
    • White box testing with branch coverage { data-correct }
    • Grey box testing with architectural knowledge
    • Random testing with automated tools
