    Ans:

    Bucket Testing, also known as A/B/n Testing, is used in marketing and software development to compare two or more versions of a product or feature. Users are randomly assigned to different “buckets” representing different versions, and their behaviour or preferences are analyzed to determine the most effective version.

    87. What are A/B Comparisons?

    Ans:

    • To determine performance, two variants (A and B) of a webpage, application, or feature are compared.
    • Users are divided into two groups, each of which is exposed to a different version.
    • Analyzes user behavior to make data-driven design or functionality decisions.
    • Determines which variant is superior in terms of user engagement or specific metrics.

    88. What is Split Testing?

    Ans:

    • In the same way that A/B Testing entails comparing the effectiveness of two iterations of a product.
    • To determine the most effective design or content, test variations of specific elements or features.
    • Users are typically exposed to one of the tested versions at random.
    • Making decisions based on user response data to improve product design or content.

    89. What are Comprehensive Examinations?

    Ans:

    Exhaustive Testing aims to test every conceivable combination of inputs and scenarios for a software application. However, due to the vast number of possibilities, it is usually impractical and not feasible to achieve complete coverage.

    90. What is Early Testing?

    Ans:

    Early Testing emphasizes starting the testing process as early as possible in the software development life cycle. By identifying and fixing defects early, the cost of addressing issues is reduced, and the overall quality of the software is improved.

    91. What is Defect Clustering?

    Ans:

    Defect Clustering is the phenomenon where a small number of modules or components contain most defects. Focusing testing efforts on critical areas identified in previous testing phases can be more effective in finding defects.

    92. What is Pesticide Paradox?

    Ans:

    The Pesticide Paradox in software testing refers to the idea that if the same set of tests is repeated over time, the effectiveness of these tests diminishes as the system evolves. To overcome this, the test suite must be regularly reviewed and updated with new test cases to find different defects.

    93. What distinguishes crowdsourced Testing from outsourcing testing?

    Ans:

    • Outsourced Testing: In Outsourced Testing, a specific testing task or project is delegated to a third-party testing service or company. The testing team is typically external to the organization developing the software.
    • Crowdsourced Testing: Crowdsourced Testing involves leveraging a diverse group of testers from various locations and backgrounds to test a software application. Testers are not part of a dedicated testing company but are individuals who contribute their testing efforts.

    94. What is Random Testing?

    Ans:

    Adhoc Testing is a non-formal method of Testing in which testers explore the application without predefined test cases or plans. Testers use their intuition, experience, and domain knowledge to identify defects ad hoc.

    95. What is Cross-Browser Testing?

    Ans:

    Cross-Browser Testing verifies that a web application works correctly and consistently across browsers (e.g., Chrome, Firefox, Safari, Internet Explorer). It guarantees a uniform user experience independent of the browser being used.
