   • Advantages:
     • Provides comprehensive coverage of the code.
     • Helps identify code defects and logic errors.
     • Ensures proper implementation of control structures and data flows.
   • Disadvantages:
     • Requires access to the source code.
     • Can be time-consuming for complex systems.
     • May overlook user experience or usability issues.

2. What is black-box testing, and what are its advantages and disadvantages?

   • Black-box testing, also known as functional testing or opaque-box testing, involves testing the software from an external perspective, without knowledge of its internal structure or code.
   • Advantages:
     • Focuses on the software’s functionality and requirements.
     • Simulates real-world usage scenarios.
     • Does not require access to the source code.

     • Cannot identify internal logic or implementation issues.
     • Requires thorough understanding of requirements and specifications.

3. Explain the concept of boundary value analysis in software testing.

   • Boundary value analysis is a testing technique that involves testing the software at the boundaries or limits of its input values.
   • It focuses on testing the behavior of the software at the minimum, maximum, and slightly above or below the valid input ranges.
   • This technique is effective in identifying defects related to boundary conditions and edge cases.

4. What is equivalence partitioning, and how is it used in software testing?

   • Equivalence partitioning is a technique that divides the input data or test conditions into partitions or equivalence classes based on their expected behavior.
   • Instead of testing every possible input value, only one or a few representative values from each partition are tested.
   • This approach helps reduce the number of test cases while still providing adequate coverage.

5. Describe the concept of test automation and its benefits.

   • Test automation involves using tools and scripts to execute test cases and validate the software’s behavior automatically.
   • Benefits of test automation include:
     • Increased test coverage and efficiency.
     • Consistent and repeatable test execution.
     • Early detection of defects and regressions.
