This assignment is a software testing theory assignment, not a coding task.

You are required to:

  • Answer 10 conceptual questions related to software testing
  • Use textbook concepts and given links
  • Write clear explanations in English
  • Submit individual work only
  • No Java code is required, only test case descriptions and explanations

    Detailed Explanation (Question by Question)

    1. Stubs and Drivers

    You need to explain:

    • The difference between top-down and bottom-up integration testing
    • Which uses stubs and which uses drivers
    • Which one is used when lower-level modules are missing and the main module needs to be tested

    2. Test Cases

    Using the provided article, explain:

    • What a test case is
    • Its purpose and importance
    • Identify different types of test cases, such as:
      • Integration test cases
      • Performance-related test cases (load, stress, spike, scalability)
      • Usability / UX test cases

    3. Unit Testing a Java Method

    You are given a Java program scenario:

    • main() is already tested
    • getMax() still needs unit testing
    • You must describe two test cases
    • No Java code is required just test scenarios

    Example format:

    • Test with normal positive integers
    • Test with negative and mixed values

    4. Testing Levels

    You must match testing levels to their purpose:

    • Beta testing by end users
    • Business requirement validation
    • Module communication testing
    • End-to-end testing
    • Testing external systems or devices

    5. Regression vs Re-testing

    Explain:

    • The purpose of regression testing
    • How it differs from re-testing
    • When each one is used

    6. Smoke Testing

    Describe:

    • A quick, basic test run after building the program
    • Done before system testing
    • Ensures the application starts and main features work without crashing

    7. Test Harness

    Based on Wikipedia:

    • Identify the two main components of a test harness
    • Explain its objectives
    • Describe how a test harness can simulate unavailable systems (e.g., a missing mainframe)

    8. Packaging and Deployment

    List:

    • The names of packaging methods discussed in the chapter
    • The general steps of a deployment pipeline (build, test, package, deploy)

    9. Version Control

    Explain the core features of version control systems, such as:

    • Version tracking
    • Branching and merging
    • Change history
    • Collaboration support
    • Rollback and recovery

    10. Testing Processes During Development

    Describe:

    • The two testing processes during development
    • How pre-commit tests help catch errors early before code is committed

    Key Tip

    This assignment tests your understanding of software testing concepts, not your ability to write code.

Requirements: 10 answers
