To answer this question, we need to understand the different types of testing in software development.
A. System testing - System testing is performed to evaluate the system's compliance with the specified requirements. It focuses on testing the entire system as a whole. Contract and regulation testing is not specifically related to system testing.
B. Acceptance testing - Acceptance testing is conducted to determine whether a system meets the acceptance criteria and to obtain customer approval for the system. Contract and regulation testing is often a part of acceptance testing as it ensures that the system adheres to the contractual obligations and regulatory requirements.
C. Integration testing - Integration testing is performed to verify the interaction between different components or modules of a system. It ensures that these components work together as expected. Contract and regulation testing is not directly related to integration testing.
D. Smoke testing - Smoke testing is a preliminary testing process that checks the basic functionalities of the system to ensure that it is stable and ready for further testing. Contract and regulation testing is not specifically associated with smoke testing.
Based on the above explanations:
Option A) System testing - This option is incorrect because contract and regulation testing is not specifically related to system testing.
Option B) Acceptance testing - This option is correct because contract and regulation testing is a part of acceptance testing to ensure compliance with contractual obligations and regulatory requirements.
Option C) Integration testing - This option is incorrect because contract and regulation testing is not directly related to integration testing.
Option D) Smoke testing - This option is incorrect because contract and regulation testing is not specifically associated with smoke testing.
The correct answer is B) Acceptance testing. This option is correct because contract and regulation testing is a part of acceptance testing to ensure compliance with contractual obligations and regulatory requirements.
