摘要:
A simulator of WBEM/CIM indication providers conforming to the CIM Indication Provider object specification simulates both the CIM indication provider and the means to drive the associated CIM events. The simulator comprises three functionally unique pieces: one or more CIM indication provider drivers, one or more CIM event trigger drivers, and a control application. This modularization creates flexibility in configuring the simulator to stress test different aspects of an operating system's underlying support for CIM indications. Modularization also makes the simulator design operating system independent. Provision is made in the simulation for generation of additional CIM events as background activity on the operating system.
摘要:
A simulator of intelligent workstations at level 2 the OSI model for generating complete LAN frames for testing a system under test. The simulator includes a scripting facility that represents the actions of the human end-user at the client workstation. By providing a scripting facility, different complexions of a workload can be impressed upon the system under test without the need for human end-users nor the need for rebuilding the simulation tool. The simulator includes embedded protocol stacks allowing manipulation of the simulated LAN frames. The simulator also includes one or more embedded protocol application modules for emulating actions of an application, e.g., web browser, and enabling the handling of dynamic, application-related events. In the present invention, one or more application programming interfaces (APIs) are provided between the simulation tool and the PAM and between the PAM and the protocol stack to allow multiple applications to be concurrently simulated and to provide extensibility of the simulation tool by providing the ability to support new applications and protocol stacks.

Based on a functional coverage by a test suite, a functional coverage model of a System Under Test (SUT) may be defined to represent all covered combinations of functional attributes. Based on an n-wise combination criteria, a subset of the possible combinations of values may be determined A subset of the test suite may be selected such that the selected subset is operative to cover the subset of the determined possible combinations of values. The disclosed subject matter may be used to reduce a size of the test suite while preserving the n-wise combinations coverage of the original test suite.
摘要:
A meta attribute useful for functional coverage is computed based on values comprised by two or more matching fields in a trace. The two or more matching fields may be comprised by a single entry of the trace or by a plurality of entries of the trace. A definition of the meta attribute may define which fields of the entries comprise values useful for computation of the meta attributes. The matching entries may be identified based on identifying values within the entries.
摘要:
A functional coverage model may be generated based on a trace. The functional coverage model may comprise values of attributes. The values may be extracted from one or more entries comprised by the trace. Based upon a selection of a field of an exemplary entry, content of the corresponding fields in other entries may be extracted and utilized. In some exemplary embodiments, names of attributes may be extracted from the trace. In some exemplary embodiments, a reference trace may be utilized as a comparative baseline coverage by generating a functional coverage model based upon the reference trace and comparing coverage of a second trace in respect to the functional coverage model with the coverage of the reference trace.

摘要:
One aspect of the present invention includes performance of a comparative functional coverage technique for comparing analysis of actual operational load data, such as customer data, with test operational load data. In one embodiment, coverage and holes analysis operations are performed on each of actual trace data produced by the operation of actual activities, and test trace data produced by the operation of a simulation within a test execution. The functional coverage and hole analysis results produced for each of the actual data source and the test data source are then compared to discover the most important functional holes relevant to testing, namely holes which appear only in the test but not within the actual operation. The results of the holes comparison detailing which holes exist within the test are then presented and ultimately utilized to improve the test.
