    摘要： Techniques and tools for testing multi-threaded or distributed software systems are described. For example, a multi-threaded system is instrumented and executed to produce logs of events that are performed by each of its agents. The agent logs contain a totally ordered series of events per agent, as well as information about accesses to resources shared between the agents. With this information, a partial ordering of the events performed by all the agents is described for the execution. The agent logs are then multiplexed into one or more serialized event orderings, which can then be compared to a specification of the system in a conformance testing engine.

    摘要： Techniques and tools for generating finite state machines (“FSMs”) for a software system with asynchronous callbacks are described. For example, method invocations in a model of the software system are partitioned into observable and controlled method invocations. The controlled method invocations are those which can be run from a test harness while the observed method invocations are those which are observed asynchronously as they are invoked in the system. An FSM is created with observation and control nodes such that observable transitions are found from observation nodes and controlled transitions are found from control nodes. If a state of the model contains both controlled and observable invocations, a timeout transition is added to the FSM to give an implementation time to come up with an observed method invocation before continuing to controlled invocations.

    摘要： A change management method and system for tool-based document generation which incorporates tool input changes, tool changes, and user changes during iterative document creation. After a tool-based document is generated and saved by a tool, and then edited by a user, during a next iteration of creating the edited document, the tool first generates a new base document. The base document is then saved, and a three-way merge is performed on the former iteration's base document, this iteration's new base document, and the former iteration's edited document. The former iteration's base document serves as the base of the merge process. The merge outputs a merged document, and when further edits are needed, the merged document is edited, and saved as the edited document. If no edits are necessary, the merged document is saved directly as the edited document. In each iteration, the new base document and the edited document are saved for a possible next iteration.

    摘要： To perform conformance checking of a software implementation with a (possibly non-deterministic) specification, a software implementation and a software specification are applied to produce a CT enabled implementation. Nondeterministic choices of the software specification result in assigning a corresponding choice of the CT enabled implementation to a variable. The CT enabled implementation includes a test that the variable then comprises one of the nondeterministic choices of the software specification. To perform conformance testing where the software specification includes ordered steps, and calls to methods of other classes (mandatory calls), a software object is produced and organized such that each step of the software specification has a corresponding code section in the software object. The software object includes instructions to generate an identification of a mandatory call comprised by the software specification, and instructions to test that the state of the implementation conforms to the software specification during the mandatory call.

    摘要： In one embodiment, a computer system provides an application programming interface (API) for augmenting an application API. A computer system receives software code written in a second programming language indicating a user's intention to augment an application API with contracts from a contract API written in a first programming language. The software code includes a reference to the contract API. The contracts include assertions indicating appropriate use of the application API. The computer system accesses portions of the contract API according to the reference in the software code and compiles the received software code and the referenced portions of the contract API into an intermediate language (IL) version of the software code. The IL version is in an intermediate language common to both the first programming language and the second programming language. The IL version includes the assertions indicating appropriate use of the application API.
