To answer this question, you need to understand the concept of acceptance testing and its purpose.
Acceptance testing is a type of software testing that is performed to determine whether a system meets the specified requirements and is ready for deployment. It is usually conducted by end-users or stakeholders to evaluate the system's functionality, usability, performance, and overall compliance with their expectations.
Now, let's go through each option to understand why it is correct or incorrect:
Option A) Beta Testing - This option is correct because beta testing is a form of acceptance testing where the software is tested by a limited number of end-users in a real-world environment before the final release. It allows for feedback and identification of issues that may not have been detected during earlier testing phases.
Option B) Greybox Testing - This option is incorrect. Greybox testing refers to a testing approach that combines elements of black-box testing and white-box testing. It focuses on testing the system's functionality while having partial knowledge of its internal structure.
Option C) Test Automation - This option is incorrect. Test automation refers to the use of software tools and scripts to automate the execution of test cases. It is a technique used to improve the efficiency and effectiveness of testing but is not specific to acceptance testing.
Option D) White Box Testing - This option is incorrect. White box testing is a testing technique that involves examining the internal structure and code of a software system. It is primarily used to verify the system's internal logic and ensure that all code paths are tested.
The correct answer is Option A) Beta Testing. This option is correct because beta testing is a form of acceptance testing where the software is tested by end-users in a real-world environment before its final release.
