Software Quality Assurance Practice Exam

The method that involves the use of test cases supplemented by black-box methods is module testing. Module testing, also known as unit testing, focuses on testing individual components or modules of the software application in isolation from the rest of the system. In this approach, black-box testing techniques are often applied, where the internal workings of the module are not considered. Instead, the testing is based on the specifications and requirements defined for that module. Test cases are created to validate the functionality of the module against these requirements, ensuring that it behaves as expected. This method is instrumental in identifying defects at an early stage of development, making it easier to fix issues before the modules are integrated with the entire system. Moreover, solid module testing contributes to higher software quality by ensuring each component is functioning correctly before further testing stages like integration or system testing. While integration, acceptance, and performance testing involve different focuses—such as examining the interactions between modules, validating the system against user requirements, or measuring performance under load and stress—module testing specifically emphasizes testing isolated pieces of code with a black-box approach, thereby making it the correct answer in this context.
