A viewer is disclosed for viewing a multi-dimensional data set. The viewer may be coupled to or included in a test environment and receive data generated in the test environment. The test environment may generate metric data from the multiple test cases of a UUT. The viewer may display the cumulative metric data generated from multiple test cases. The viewer may display the cumulative metric data in a fashion that the user can gain insight into the UUT's characteristics.

Viewing multi-dimensional metric data from multiple test cases

Generating cumulative metric data for a test in a test environment includes: generating in the test environment a test for a simulation model of a system under test; generating in the test environment at least one test condition for the test, the at least one test condition determining a plurality of iterations of the simulation model; generating in the test environment at least one temporary test variable for the test; generating in the test environment at least one mapping between a metric setting for the simulation model and one of the temporary test variables; running in the test environment the test for the plurality of iterations, wherein metric data for the simulation model is generated for each mapping and for each iteration of the test; and accumulating in the test environment the generated metric data for each mapping and for each iteration of the test to obtain cumulative metric data for the simulation model.

Test environment for accumulating cumulative metric data

A method for testing a system under test includes defining a test having a number of test elements where at least one of the test elements corresponds to a simulation model with a metric setting. A test vector is defined for the test, and it is used to determine a number of test iterations. The metric setting of the simulation model is mapped to a test variable, and when the test is run metric data is generated from the simulation model during each test iteration. The metric data generated for each test iteration is accumulated and displayed.

In a computer-implemented method for running a test, the test to test a system under test is generated. At least a portion of the test is designated to be run as a distributed test. The designated test portion is selected to be run in one of a synchronous execution mode or an asynchronous execution mode. Tasks of the generated test are distributed to a plurality of workers. The distributed tasks are run with the plurality of workers according to the execution mode selection.

Test environment having synchronous and asynchronous distributed testing

A mechanism for the distribution of a test vector for a system test to a parallel computing environment is discussed. A test vector which controls the parameterization of a system test being conducted is provided as an input parameter to a function. In one implementation, the test vector is declared as a distributed array data type. The processing of the input test vector parameter causes the test vector to be distributed to the parallel computing units holding portions of the system under test. The test vector is then used in executing the system test. The results of the execution of the system test using the test vector may then be saved in a distributed array or returned to a client for presentment to a user.
