    ABSTRACT

    The Test Template Framework (TTF) is a formal, abstract model of testing, used to derive a hierarchy of test information, including test inputs and outputs, from a model-based formal specification.

    In this paper we propose two modifications to the framework: first, that testing information derived from state components be factored out from operation-specific information, and second, that focusing on the input space of an operation under test be deferred for as long as possible.

    The first modification facilitates reuse of derived information in the context of abstract data types (ADTs) and classes to minimise duplication.

    The second modification supports testing strategies based on operation outputs, and provides a basis for further extensions for testing derived from behaviour-based notations.
