beta test
beta version
Evaluation of a pre-release (potentially unreliable)
version of a piece of software (or possibly hardware) by
making it available to selected users ("beta testers") before it
goes on general distribution.
Beta testign aims to discover bugs that only occur in certain
environments or under certain patterns of use, while reducing the
volume of feedback to a manageable level. The testers benefit by
having earlier access to new products, features and fixes.
Beta testing may be preceded by "alpha testing", performed
in-house by a handful of users (e.g. other developers or friends),
who can be expected to give rapid, high quality feedback on design
and usability. Once the product is considered to be usable for
its intended purpose it then moves on to "beta testing" by a
larger, but typically still limited, number of ordinary users, who
may include external customers.
Some companies such as Google or {Degree Jungle
(http://www.degreejungle.com/rankings/best-online-colleges)}
stretch the definition, claiming their products are "in beta" for
many months by millions of users.
The term derives from early 1960s terminology for product cycle
checkpoints, first used at IBM but later standard throughout the
industry. "Alpha test" was the unit test, module test or
component test phase; "Beta Test" was initial system test.
These themselves came from earlier A- and B-tests for hardware.
The A-test was a feasibility and manufacturability evaluation done
before any commitment to design and development. The B-test was a
demonstration that the engineering model functioned as specified.
The C-test (corresponding to today's beta) was the B-test
performed on early samples of the production design.
