To answer this question, you need to understand the concept of function libraries.

Option A) True - This option is correct. You can work on one or several function libraries at the same time. Function libraries are collections of pre-written functions that can be reused in multiple programs or projects. These libraries can be used simultaneously in different programs or projects to save time and effort.

Option B) False - This option is incorrect. It is possible to work on multiple function libraries simultaneously.

The correct answer is A) True.

To answer this question, we need to understand the Software Development Life Cycle (SDLC) process and when the test process can start.

The SDLC process consists of several phases, including requirements gathering, design, development, testing, and maintenance. Each phase has its own set of activities and deliverables.

The correct answer is C) When the software requirements have been approved.

Explanation for each option:

A) When the code is complete - This option is incorrect because testing should not be delayed until the entire code is complete. Testing should start as early as possible in the SDLC process to identify and fix issues at an early stage.

B) When the design is complete - This option is incorrect because testing should not wait until the design is complete. Testing should begin before the design phase to ensure that the requirements are testable and to identify any potential issues or inconsistencies.

C) When the software requirements have been approved - This option is correct. Testing should start once the software requirements have been approved. This allows the test team to verify that the requirements have been properly implemented and to identify any gaps or discrepancies.

D) When the first code module is ready for unit testing - This option is incorrect because testing should not wait until the first code module is ready for unit testing. Testing should start earlier in the SDLC process to identify and fix issues before they propagate to subsequent phases.

In conclusion, the correct answer is C) When the software requirements have been approved. This ensures that testing can begin early in the SDLC process and helps to identify any issues or gaps in the software requirements.

To answer this question, you need to understand the concept of impact analysis. Impact analysis is the process of identifying the potential effects or consequences of a change in a system. It helps in determining the areas or components that may be affected by the change and allows for better decision making.

Let's go through each option to understand why it is correct or incorrect:

Option A) How much regression testing should be done - This option is correct because impact analysis helps in assessing the impact of a change on the system and its components. It helps in determining which parts of the system need regression testing to ensure that the changes have not introduced any unintended side effects.

Option B) Exit Criteria - This option is incorrect. Exit criteria are predefined conditions or requirements that must be met before a testing phase can be considered complete. While impact analysis may inform the exit criteria, it is not directly related to deciding exit criteria.

Option C) How many more test cases need to be written - This option is incorrect. Impact analysis helps in identifying the areas affected by a change, but it does not directly determine the number of test cases that need to be written. Test case creation is based on the requirements and functionality of the system, not just the impact of a change.

Option D) Different Tools to perform Regression Testing - This option is incorrect. Impact analysis focuses on assessing the impact of changes on the system, not on the tools used for regression testing.

The correct answer is A) How much regression testing should be done. This option is correct because impact analysis helps in determining the extent of regression testing needed to ensure that the changes have not introduced any unintended side effects.
