A finest Adaptive tests can be seen as trees representing the strategy of the tester in a game against the implementation. We say that an implementation passes resp. For example, the edge labeled a? We assume that the implementation i. Tester B. The second branch of Spec2 is a typical specification of a timeout. When the specification is inputcomplete, tioco and TTI are equivalent. This permits to capture the fact that an implementation producing an output too early or too late or never, whereas it should is nonconforming. The definition naturally extends to a set of states S.

    We propose a new framework for black-box conformance testing of real-time systems, where specifications are modeled as non-deterministic and.
    We also need to ensure that the test does not block time, for instance, by emitting an infinite number of inputs in a bounded amount of time.

    Conformance Testing of Distributed Concurrent We follow the same convention when drawing test automata. This transformation is not always possible for non-deterministic specifications. This notation extends to timed sequences, in the usual way.

    Analog-clock tests are problematic, since they are difficult, if not impossible, to implement with finite-precision clocks.

    In this paper, we lift the above limitations. We propose algorithms to generate two types of tests for this setting: analog-clock tests which measure dense time precisely and digital-clock tests which measure time with a periodic clock. The IF modeling language allows to specify systems consisting of many processes communicating through message passing or shared variables and includes features such as hierarchy, priorities, dynamic creation and complex data types.

    Such specifications arise often in practice: when the model is built compositionally, component interactions are typically non-observable to the external world; abstraction from low-level details often results in non-determinism.

    Synchrony and Asynchrony in Conformance Testing - ceres. We argue that such a model is essential for ease of modeling and expressiveness of specifications.

    The framework is based on the model of partially-observable.
    Notice that we cannot use the technique of [19], which is based on formulating coverage as a reachability problem. We are thus motivated to define another notion. Algebraic Independence and Blackbox Identity Testing. The test shown in Figure 3 is sound and strict w. If e is an edge of AS labeled with a and enabled at some state in S, then we say that e is covered by T.

    We represent an analog-clock test as an algorithm.

    We discuss this option in more detail in Section 5.

    The algorithm extends the test by adding successors to a leaf node, as Generic test-generation scheme. It is assumed that higher and lower is modulo three, thus, a single touch while the light is bright turns it off.

    We have applied our tools on several online games to verify the effectiveness of our method. A number of issues arise, regarding the appropriateness of the models and conformance relation, the correctness of the testing process, its adequacy, its efficiency, and so on.

    CiteSeerX — Blackbox conformance testing for realtime systems

    We propose a new framework for black-box conformance testing of real-time systems, based on the model of timed automata. The framework is expressive: it.
    In the case of timed automata the state space is infinite, thus, existing methods attempt to cover: either finite abstractions of the state space, e.

    This permits to capture the fact that an implementation producing an output too early or too late or never, whereas it should is nonconforming. For all illegal outputs ai outputs which cannot occur from any state in S the test leads to fail.

    However, checking this and performing the determinization is undecidable [32]. A survey of coverage criteria and their relationships, in the context of software testing, can be found in [33].

    Input-completeness is required so that the implementation can accept inputs from the tester at any state possibly ignoring them or moving to an error state, in case of illegal inputs.

    The framework is based on the model of partiallyobservable, nondeterministic timed automata.

    Assessment of conformance and interoperability testing There are different types of tests, depending on the capabilities of the tester to observe and react to events.

    Soundness is a minimal correctness requirement. But an implementation could be conforming up to a certain point and not conforming afterwards.
