Which phase focuses on assessing software for errors?

• A. Test Phase
• B. Design Phase
• C. Maintenance Phase
• D. Deployment Phase

Answer: (A)

Testing is the phase where the software is evaluated to find defects and confirm it behaves as expected. In this stage you run test cases, check that features work correctly, and identify and fix errors before release. The goal is to expose issues so they can be corrected, ensuring quality and reliability for users.

The design phase, in contrast, focuses on planning the system’s structure and how components will interact. Deployment is about releasing the software to users, and maintenance handles updates and fixes after it’s in use. So the phase dedicated to assessing software for errors is testing.
