Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What is alpha testing?

    Model answer

    Alpha testing is testing of a nearly complete product carried out inside the developer's own organisation, under controlled conditions, before anyone outside sees it.

  2. 2

    Who carries out alpha testing?

    Model answer

    Alpha testing is carried out by the developer's own staff, usually testers and employees who were not involved in writing the code.

  3. 3

    What is beta testing?

    Model answer

    Beta testing releases a pre-release version to a limited group of real users outside the developer's organisation, who use it in their own conditions and report the problems they meet.

  4. 4

    Give two reasons for beta testing a product after alpha testing.

    Model answer

    Beta testing exposes the software to a far wider range of hardware and settings than the developer owns, and to patterns of use the developer never thought to try.

  5. 5

    Distinguish between a closed beta and an open beta.

    Model answer

    A closed beta is limited to an invited group of testers, while an open beta is available to anyone who chooses to try the pre-release version.

  6. 6

    Give one advantage of a closed beta over an open beta.

    Model answer

    A closed beta keeps an unfinished product away from the general public and from competitors, and an invited group is more likely to report faults carefully.
