The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

Correct Answer: (D) Big-Bang testing<\/strong><\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

Big-Bang Testing<\/strong> is a type of software integration testing in which all or most of the developed modules are coupled together to form a complete system<\/strong>, and then testing is carried out as a whole. It is usually done after all individual modules are developed and unit tested<\/strong>, but without performing incremental integration testing.<\/p>\n\n\n\n

Characteristics of Big-Bang Testing:<\/h4>\n\n\n\n
    \n
  • Integration of All Modules<\/strong>: In this approach, all modules are integrated at once instead of one at a time. This is where the term \u201cBig-Bang\u201d comes from \u2014 everything is brought together in one large integration phase.<\/li>\n\n\n\n
  • No Incremental Integration<\/strong>: Unlike top-down or bottom-up approaches, Big-Bang does not follow a phased or hierarchical integration method. There\u2019s no sequence or control over how modules are combined.<\/li>\n\n\n\n
  • System as a Whole<\/strong>: Since all modules are combined before testing, the entire system is tested as a complete unit<\/strong>.<\/li>\n<\/ul>\n\n\n\n

    Advantages:<\/h4>\n\n\n\n
      \n
    • Simplicity<\/strong>: The process may seem simpler since you do not need to plan detailed incremental testing steps.<\/li>\n\n\n\n
    • Time Saving Initially<\/strong>: Developers can focus on building modules without worrying about integration until all components are ready.<\/li>\n<\/ul>\n\n\n\n

      Disadvantages:<\/h4>\n\n\n\n
        \n
      • Defect Isolation is Difficult<\/strong>: When issues arise, it becomes hard to determine which module caused the problem.<\/li>\n\n\n\n
      • High Risk<\/strong>: If major bugs are found during system testing, it can delay the project significantly.<\/li>\n\n\n\n
      • Delayed Feedback<\/strong>: Since integration happens late, problems are discovered much later in the development cycle.<\/li>\n<\/ul>\n\n\n\n

        Comparison with Other Options:<\/h4>\n\n\n\n
          \n
        • Top-down testing (B)<\/strong> integrates modules from the top of the hierarchy downwards.<\/li>\n\n\n\n
        • Bottom-up testing (A)<\/strong> begins testing from the lowest levels and moves up.<\/li>\n\n\n\n
        • Sandwich testing (C)<\/strong> is a hybrid of top-down and bottom-up testing.<\/li>\n<\/ul>\n\n\n\n

          Thus, since all modules are integrated and tested as a complete system at once<\/strong>, the correct answer is (D) Big-Bang testing<\/strong><\/p>\n\n\n\n
