To answer this question, you need to understand the concept of objective testing. Objective testing is a type of testing that focuses on verifying the system's functionality and behavior according to predefined specifications or requirements, without any bias or subjective judgment.
Let's go through each option to understand why it is correct or incorrect:
Option A) Unit Testing - This option is incorrect because unit testing is a type of testing that focuses on testing individual units or components of a system in isolation. It primarily verifies the correctness of the code and ensures that each unit functions as expected. While unit testing is important, it may not necessarily encourage objective testing as it focuses on specific units rather than the system as a whole.
Option B) System Testing - This option is incorrect because system testing is a type of testing that focuses on testing the entire system as a whole to ensure that all components work together correctly and meet the specified requirements. While system testing is crucial for verifying the system's behavior, it may involve subjective judgment or bias, especially when evaluating user interfaces or user experience aspects.
Option C) Independent Testing - This option is correct because independent testing refers to testing conducted by individuals or teams who are not directly involved in the development of the system. Independent testers bring an unbiased perspective and can objectively evaluate the system against the specified requirements. This type of testing helps identify any deviations or discrepancies from the desired behavior without any subjective bias.
Option D) Destructive Testing - This option is incorrect because destructive testing is a type of testing that aims to determine the system's behavior under extreme or abnormal conditions, such as stress testing or load testing. While destructive testing is important for assessing the system's robustness and resilience, it may not necessarily focus on objective evaluation of the system's functionality.
The correct answer is Option C) Independent Testing. This option encourages objective testing as it involves individuals or teams who are not directly involved in the development process, ensuring an unbiased evaluation of the system's functionality against the specified requirements.
