.................. testing involves delivering a system to a number of potential customers who agree to use that system.

  • A.Unit
  • B.Beta
  • C.Alpha
  • D.Validation

Answer: B

This is beta testing.

In beta testing an early release of the system is delivered to a number of potential customers who agree to use it in their own environments and report problems, revealing issues the developers could not anticipate.

Alpha testing has users work with the developers, usually at the developer's site. Unit testing checks individual components, and validation testing shows that the software meets its requirements. None involves releasing the system to outside customers.
