What does component testing primarily focus on?

• A. Defects in interfaces
• B. Defects in whole test objects
• C. Defects in separately testable modules
• D. Defects not focused on identifying

Answer: (C)

Component testing primarily focuses on defects in separately testable modules or components of a software system. In this testing approach, individual parts of the software—such as functions, classes, or modules—are examined in isolation from the rest of the application. The purpose of this testing is to identify and address any issues within these specific components before they are integrated into larger systems. By concentrating on individual modules, testers can ensure that each component operates correctly and meets its specifications, leading to a more reliable overall system. This focus on isolating and testing components allows for more precise debugging and higher-quality software, as defects can be identified and resolved at an early stage in the development cycle. Therefore, the emphasis on testing modules separately is what sets component testing apart from other types of testing that might look at the system as a whole or at the interactions between various components.
