Ada Conformity Assessment Test Suite

[1] The test suites were modeled on a VAX/VMS system,[3] which was the dominant host platform for such defense-related applications at the time.

Some of the tests were composed using orthogonal Latin squares as an approach towards get the most effective coverage of language feature combinations without employing an exhaustive enumeration of them.

[4] There was an organization set up to review queries vendors raised as to whether a certain aspect of one or more tests was an accurate reflection of the language standard.

[2] At the height of the language's use, which corresponded to the years 1985 through 1993, there were five Ada Validation Facilities around the world that could process vendor ACVC submissions: the Language Control Facility at Wright Patterson Air Force Base (United States), the National Bureau of Standards (United States, soon renamed to the National Institute of Standards), the National Computing Centre (United Kingdom), AFNOR (France), and IABG (Germany).

[2] However once Ada use for defense or similar applications began falling, the number of validation contracts fell as well, and several of these facilities became inoperative or transferred their responsibilities.
