Unit Testing. Testing performed to
isolate and expose faults and failures as soon as the source code is available,
regardless of the external interfaces that may be required. Oftentimes, the
detailed design and requirements documents are used as a basis to compare how
and what the unit is able to perform. White and black-box testing methods are
combined during unit testing.
Usability
testing.
Testing for 'user-friendliness'. Clearly this is subjective, and will depend on
the targeted end-user or customer.
Validation. The comparison between the
actual characteristics of something (e.g. a product of a software project and
the expected characteristics).Validation is checking that you have built the
right system.
Verification The comparison between the
actual characteristics of something (e.g. a product of a software project) and
the specified characteristics.Verification is checking that we have built the
system right.
Volume testing. Testing where the system is
subjected to large volumes of data.[BS7925-1].
Walkthrough In the most usual form of
term, a walkthrough is step by step simulation of the execution of a procedure,
as when walking through code line by line, with an imagined set of inputs. The
term has been extended to the review of material that is not procedural, such
as data descriptions, reference manuals, specifications, etc.
White Box Testing (glass-box). Testing is done under a structural testing
strategy and require complete access to the object's structure¡that is, the
source code.[B. Beizer, 1995 p8]
