A Test Case Generation Algorithm for Real-Time Systems .

Abstract
In this paper, we describe how the real-time verification
tool UPPAAL has been extended to support automatic generation
of time-optimal test suites for conformance testing.
Such test suites are derived from a network of timed automata
specifying the expected behaviour of the system under
test and its environment. To select test cases, we use coverage
criteria specifying structural criteria to be fulfilled by
the test suite. The result is optimal in the sense that the set of
test cases in the test suite requires the shortest possible accumulated
time to cover the given coverage criterion.
The main contributions of this paper are: (i) a modified
reachability analysis algorithm in which the coverage
of given criteria is calculated in an on-the-fly manner, (ii) a
technique for efficiently manipulating the sets of covered elements
that arise during the analysis, and (iii) an extension
to the requirement specification language used in UPPAAL,
making it possible to express a variety of coverage
criteria.
