Component testing may include:

Component testing, also known as unit testing, focuses on evaluating individual components or modules of the software to ensure they function correctly in isolation before integrating them with other parts of the system.

The use of stubs and drivers is a vital aspect of component testing as it addresses the challenge of testing components that may not have all their dependencies in place. Stubs simulate the behavior of lower-level components that are not yet integrated, and drivers simulate the higher-level components that call the component being tested. This setup allows for focused testing of the specific piece of code, ensuring it behaves as expected while controlling for interactions with other components.

In contrast, the other options refer to different types of testing methodologies or contexts that are not suitable for component testing. Sociability testing, user acceptance testing, and beta testing involve broader considerations beyond individual components, typically focusing on the system as a whole or user interactions rather than the isolated functions or behavior of a singular component. These are more aligned with integration testing, system testing, or user testing phases rather than the specific focus of component testing.
