To answer this question, you need to understand the concepts of reviews, inspections, and testing.

Reviews and inspections are activities that involve examining and evaluating a system or its components, typically in the form of documentation or code, to identify defects, improve quality, and ensure compliance with requirements. These activities are performed by individuals or teams who are knowledgeable about the system being reviewed.

On the other hand, testing is the process of executing a system with the intent of finding defects or verifying that it satisfies specified requirements. Testing involves activities such as planning, designing test cases, executing them, and analyzing the results.

Now, let's go through each option to understand why it is correct or incorrect:

Option A) No, because they apply to development documentation - This option is incorrect because reviews and inspections can be performed on various types of documentation, not just development documentation. They can be applied to requirements documents, design documents, test plans, test cases, and more.

Option B) No, because they are normally applied before testing - This option is incorrect because reviews and inspections can be conducted at any stage of the development lifecycle, including before, during, and after testing. They are not limited to being performed only before testing.

Option C) No, because they do not apply to the test documentation - This option is incorrect because reviews and inspections can be applied to test documentation, such as test plans and test cases. They aim to ensure that the test documentation is accurate, complete, and effective in identifying defects.

Option D) Yes, because both help detect faults and improve quality - This option is correct because reviews and inspections are part of the broader quality assurance activities, which include testing. They help detect faults, identify areas for improvement, and enhance the overall quality of the system.

Option E) Yes, because testing includes all non-constructive activities - This option is incorrect because testing is a specific activity focused on executing the system and verifying its behavior against specified requirements. Reviews and inspections, although non-constructive in nature, are separate activities that complement testing.

The correct answer is Option D. This option is correct because reviews and inspections are part of the quality assurance process and contribute to detecting faults and improving the quality of the system.

To answer this question, we need to understand the concept of regression testing. Regression testing is a type of software testing that is performed to ensure that previously developed and tested software still performs correctly after changes or additions have been made. It helps identify any defects or issues that may have been introduced due to these changes.

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

Option v) every week - This option is incorrect because regression testing should not be performed every week. The frequency of regression testing should be determined based on the software changes and other factors.

Option w) after the software has changed - This option is correct because regression testing should be performed after the software has changed. It helps ensure that the existing functionality has not been affected by the changes.

Option x) as often as possible - This option is incorrect because regression testing should not be performed as often as possible. The frequency of regression testing should be determined based on the software changes and other factors.

Option y) when the environment has changed - This option is correct because regression testing should be performed when the environment has changed. Changes in the environment can impact the functioning of the software, and regression testing helps identify any issues caused by these changes.

Option z) when the project manager says - This option is incorrect because regression testing should not be performed solely based on the project manager's decision. The decision to perform regression testing should be based on factors such as software changes and environmental changes.

Based on the explanations above, we can see that options w and y are true, while options v, x, and z are false.

Therefore, the correct answer is option C) w & y are true, v, x & z are false.
