Description
Technical field
The present invention relates to communication technical field, relate in particular to the automatic generation of test topology figure of data product automatization test system and the automatic checking device and the method for test topology structure.
Background technology
Fast development along with data communication industry, various data communication new technologies and emerging data communications equipment emerge in an endless stream, it is also developed in large quantities and use to be used for the means of testing of data communications equipment test and various special use, universal test instrument (also can be called test instrumentation, down with).But along with improving constantly of testing level and deepening continuously of levels of testing, each side to testing tool requires also constantly improving, testing tool is except can satisfying the primary demand on the test function, also to satisfy the demand on the service efficiency, operation test that can be good and fast, for data communications equipment manufacturer saves the testing time, reduce R﹠D costs.
In the middle of the data communications equipment test process of reality, the testing tool type that the Test Engineer uses is often a kind of incessantly, and the function of the data communications equipment of testing is also a lot, if whole test process is only used a kind of testing tool and the simple function of test data communication equipment only, can not run into too big problem, but when a plurality of functions in the face of multiple testing tool and data communications equipment participate in test, more insoluble problem will occur, be described below:
In the test event of some more complicated, the Test Engineer builds the Test Networking environment according to the requirement of test event, and the test topology structural information of actual Test Networking environment described in testing tool, the way that this step is traditional is the mode operational testing instrument that testing tool generally all offers user GUI (interface user interface), the characterising parameter of Test Engineer by GUI input test topology to test macro (by testing tool, compositions such as equipment under test and test cases storehouse Test Case Suites) transmit the topology information of testing, such as information such as test lead slogan and IP addresses.Mainly there are following three problems in this step:
First problem: general testing tool is indifferent to the information of equipment under test, so the topology information in the testing tool is imperfect.
Second problem: because the GUI interface that different testing tools provides is all inequality mostly, so if a test environment has polytype testing tool, the Test Engineer will do different input operations to identical topology information.
The 3rd problem: finish the input of various topology information characterising parameters as the Test Engineer after, the Test Engineer can only check the configuration of each test instrumentation one by one, can't directly judge on the whole from test topology whether the test topology structural information the test macro is consistent with the situation of reality, and because the mistake that the test topology information configuration causes is often after test run is finished, can find as a result the time by Test Engineer's analytical test, must cause the testing time waste.
Therefore, need a kind of device and method that topological diagram generates and topological structure is checked that can be rapidly and efficiently, generate the topology diagram of an integral body, the Test Engineer can distinguish different testing tools by this topology diagram, and whether the topology information that is easy in the checkout system is correct.
Summary of the invention
Technical problem to be solved by this invention is, the device and method that a kind of topological diagram generates and topological structure is checked is provided, when test, topology information according to input generates topology diagram automatically, mode with figure is revised the topological structure configuration intuitively according to topology diagram, and realize the topological structure of test cases is carried out automatic inspection, to improve test speed and efficient.
(after treating that claim is appraised and decided, additional complete by us, submit)
Adopt the device and method that topological diagram of the present invention generates and topological structure is checked, compared with prior art, can make testing tool when the input test topology information, possess good operation interface, reduced since the test result actual effect that causes of test topology structural arrangements mistake and operating time waste, improved testing efficiency.
