Which phase comes after Alpha testing?

• A. Beta testing
• B. Alpha testing again
• C. Unit testing
• D. System testing

Answer: (A)

Beta testing is the next phase after alpha testing. Alpha testing is done inside the organization with internal testers to catch obvious issues and verify features before exposing the product publicly. Once that work is underway or completed, beta testing kicks in by letting a limited external group use the software in real-world conditions. The goal is to uncover issues and gather feedback that couldn’t appear in the controlled internal testing environment. Unit testing happens earlier, focusing on individual components; system testing examines the integrated system often at a later stage. Repeating alpha testing isn’t the usual flow, so beta testing fits as the subsequent step.
