What
"A human action that produces an incorrect result." [IEEE]
BS
7925-1.British Computer Society Specialist Interest Group in Software
Testing (BCS SIGIST)
The action can be as simple as a typo or completely misreading the
requirements. The incorrect result may lead to a fault. For example a typo is an error. But if the typo is
in a path in the code that is never traversed in operation, then a fault
will not occur.
Why?
Because we are human!
Who?
Anyone involved in the development lifecyle. Testers
included. For example a developer generates a fault for the third time,
which is then discovered by a tester, who raises it. The tester however does
nothing to prevent it happening a fourth time. The tester here is also
making an error, in perpetuating fault creation.
