Software Quality Assurance Practice Exam

What type of testing primarily focuses on code level testing?

1. System testing

2. Integration testing

3. Module testing

4. User acceptance testing

The correct answer is: Module testing

Module testing, also known as unit testing, is primarily focused on code-level testing. This type of testing involves examining individual components or modules of the software to ensure that each part functions correctly in isolation. It allows developers to validate the logic of specific sections of code, enabling them to identify defects at an early stage in the development process. By focusing on small units of code, module testing contributes significantly to the overall quality of the software, as it helps to pinpoint issues before integrating those modules into larger systems. In contrast, system testing assesses the entire system's compliance with specified requirements, evaluating the interactions between all integrated components. Integration testing involves combining and testing multiple modules together to ensure they work as intended when interfaced. User acceptance testing focuses on the final product from the end-user's perspective, verifying that it meets their needs and requirements before it is released into production. Each of these other testing types plays an important role in the software development lifecycle, but module testing is distinctly tailored to scrutinizing the code at its most granular level.
