Which of the following types of software testing focuses

Solution

Integration Testing is focused on ensuring that newly added or integrated code works seamlessly with the existing modules of a system. It involves testing the interaction between various modules or components to ensure that they work together as expected. This type of testing typically follows unit testing and is essential for identifying issues in data flow, interface mismatches, or module interactions. Option A (Unit Testing) is incorrect because unit testing focuses on testing individual components or functions in isolation. Option B (Black Box Testing) is incorrect because Black Box Testing is concerned with testing the software without knowing its internal code structure, and it can be applied at multiple levels, not just for integration. Option D (Regression Testing) is incorrect because regression testing ensures that changes or new features do not break existing functionality, but it does not specifically focus on module integration. Option E (UAT) is incorrect because User Acceptance Testing is conducted by end-users to verify that the system meets their requirements and is ready for deployment, not for testing integration.
