A test manager software program includes an interactive test graphical-user-interface (GUI) for testing network devices using high-level networking commands. The test GUI allows the test engineer user to enter high-level commands such as Simple Networking Management Protocol (SNMP) commands that read values in a management information database in a network device under test. The high-level commands can be sent from the test manager using a command-line interface (CLI) in a telnet session opened to the network device during testing. The user specifies high-level test, analyze, and restore commands in test cases that are collected into test suites. Rules for logging on to the network device under test are stored that include expected prompts from the network device and user responses such as passwords. Addresses of the network device under test can be re-mapped for testing other devices so the test suites can be reused.

A probe card of a wafer test system includes one or more programmable ICs, such as FPGAs, to provide routing from individual test signal channels to one of multiple probes. The programmable ICs can be placed on a base PCB of the probe card, or on a daughtercard attached to the probe card. With programmability, the PCB can be used to switch limited test system channels away from unused probes. Programmability further enables a single probe card to more effectively test devices having the same pad array, but having different pin-outs for different device options. Reprogrammability also allows test engineers to re-program as they are debugging a test program. Because the programmable IC typically includes buffers that introduce an unknown delay, in one embodiment measurement of the delay is accomplished by first programming the programmable IC to provide a loop back path to the test system so that buffer delay can be measured, and then reprogramming the programmable IC now with a known delay to connect to a device being tested.

A test structure for testing graphical user interface applications (GAPs) modularizes test scripts by separating statements that define GAP test logic from statements that navigate to GAP objects. Composition rules weave the statements together to generate the test scripts that are executed to test the GAP. Because the test structure is modular, test logic can be reused across different GAPs and different versions of the same GAP. Reusing test logic is not only an efficient practice from a test engineer's point of view, but also leads to a reduction in test programming errors. The modular test structure also facilitates the efficient modification of test scripts to account for modifications in the underlying GAPs, greatly reducing the time, cost, and resource expenditures needed to arrive at updated test scripts.

Disclosed is a method for using source code to create the models used in model-based testing. After exploring the intended behavior of a software package, a test engineer writes source code to model that intended behavior. The source code is compiled into a model, and the model is automatically analyzed to generate numerous test scripts that can exercise the behavior of the software package. When the tests are run, their results are compared against intended behaviors, and discrepancies are used to correct the software package (or to correct the source-code model if it was prepared incorrectly). The model coding, test generation, test execution, and comparison steps are repeated as often as necessary to thoroughly test the software package. In some embodiments, the test scripts generated by the model are written in XML (Extensible Markup Language), allowing the easy integration of the test scripts with a number of XML-based tools.

A tool to aid a test engineer in creating a concurrent test plan. The tool may quickly map test system resources to specific pins to satisfy the requirements of a concurrent test. The tool may project test time when such a mapping is possible. When a mapping is not possible, the tool may inform its user, including making suggestions of additional resources that could allow the test system to perform the test or suggestions for other variations in input parameters that would allow a mapping. The tool employs an assignment process in which groups of associated pins are identified, along with associated resource requirements for each group. Groups of test system resources that collectively fulfill a higher level requirement are identified and the assignment is made by mapping resource sets to resource groups, using ordering and matching heuristics to reduce processing time.

Production information for ASIC (Application Specific Integrated Circuit) devices is stored in a database of a remote host system, and data necessary for a test program which controls testers for testing the IC devices are automatically created and transmitted to a tester host. This automatic system collects the data necessary for the test condition from the remote host database; creates the test condition by comparing the collected data with a predetermined handling condition; transmits the test condition to a tester host which controls a plurality of testers using corresponding test programs; and loads the test condition into the corresponding test program. This system avoids human errors which often result when test engineers write test conditions manually, and also allows quick response to a situation when new specific IC devices are required by a customer.

The present invention enables the modeling of plural outcomes resulting from a single stimulus, thereby allowing for automated test generation for non-deterministic software. In accordance with the present invention, a method, system, and computer program product are disclosed for testing software having a non-deterministic outcome. In accordance with the present invention, a set of rules is created, each rule having an associated stimulus, a precondition computation, and a computation procedure to produce the set of all valid outcome states. Each valid outcome state models one of several states that may result from applying the stimulus to any state which satisfies the precondition computation. Using these models, a test generation program is executed against the set of rules to recursively expand each path associated with an outcome state of a rule and outputting a list of valid possible outcomes, then selecting sequences of stimuli in accordance with coverage goals set by the test engineer. A test execution engine is then run against the application under test applying the sequences of stimuli to the software and a list of observed states resulting from the application of the stimuli is compiled. Finally, the list of observed states is compared with the list of valid possible outcome states to identify defects (as well as to identify correct outcomes) in the application under test and ensure the attainment of the coverage goals.
