TESTING FRAMEWORK FOR CONTROL DEVICES

摘要

The present disclosure generally relates to the automated testing of a system that includes software or hardware components. In some embodiments, a testing framework generates a set of test cases for a system under test using a grammar. Each test case may perform an action, such as provide an input to the system under test, and result in an output from the system under test. The inputs and outputs are then compared to the expected results to determine whether the system under test is performing correctly. Specifically, the system under test may be analyzed to determine whether it is capable of properly processing control instructions and input signals and/or generating expected output control signals and additional control/feedback information. The data can then be interpreted in the grammar system and/or used as input to a fault isolation engine to determine anomalies in the system under test.

主权项

1. A method for testing comprising:
causing transmission of at least one input signal to a device under test, wherein the at least one input signal includes, at least in part, a control instruction instructing at least one change in an operating state of the device under test; obtaining at least one output signal from the device under test, wherein the at least one output signal is responsive to the at least one input signal; and assessing a fault state of the device under test based, at least in part, on the at least one output signal wherein at least one attribute of the at least one output signal corresponds to an indication of an expected change in the operating state of the device.
