Technical Field
The disclosure relates to a method and a system for executing and debugging a test program.
Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
A test system is called an Automatic Test System (ATS), which is a system that automatically measures and processes data and displays or outputs test results in a proper manner with little or no human involvement. Compared with manual testing, automatic testing saves time and labor.
The development of automatic test equipment (ATS) has gone through three stages:
(1) special test equipment is adopted.
(2) And connecting related equipment by adopting a standardized General Purpose Interface Bus (GPIB).
(3) The computer and the test equipment are integrated, and computer software is used to replace some hardware functions in traditional equipment, so that the computer can be used to produce excitation, complete test function and generate test program.
In the third stage of ATS development, the problem of integrated control of test instruments is well solved, but in the current society with extremely high degree of networking, the problem becomes a backward component that can only be executed by stand-alone control, and if the test cannot be networked, the test means that the test cannot be compatible with many networking resources, technologies and implementation manners, and even the test cannot be industrially implemented by 4.0.
Thus, some vendors' test software have begun to run from locally developed, locally executed to locally developed, online solutions. Most of the existing solutions utilize local test program development software to develop and debug the test program, a certain upper computer in the network performs online control of the test engine, and a test program execution engine performs final local test execution, wherein the engine is generally stripped from the execution part of the executable program in the third stage.
The solution needs test developers to carry out long-term business trip, field development and field debugging, the personnel cost is high, the debugging efficiency is low, and the local execution of the test program is not beneficial to the sharing of test information and the unified monitoring of the test state and is also not beneficial to the information collection in the test process.

The Datasocket technology is based on COM and ActiveX of Microsoft, highly encapsulates TCP/IP protocols, and realizes cross-computer, cross-language and cross-process real-time data sharing. The technology does not have cross-operating system characteristics because the COM technology of Microsoft is utilized, and the technology of NI corporation is not open, so that the usability of the technology on other test system software is greatly limited.
LabView of NI company can realize local development, debugging and online execution by using Datasket technology or Remote Panel (Remote Panel) technology, and the solution is only an intermediate turn of the future stage of automatic test, and the online development, debugging and execution state of the test program is the final form of the next stage of automatic test.
Taking a database technology developed by LabView of NI corporation as an example, the technology interacts with a remote end through a package communication layer outside an execution engine of LabView, so as to receive remote control for test execution and test state feedback, as shown in fig. 5, the method can meet the remote online execution of a test program, but cannot meet the online development and debugging of the test program.
As shown in fig. 5, the communication protocol a side is paired with the communication protocol B side for controlling the instrument. The method has the advantages that manufacturers developing the test execution software can separate and independent the test execution engine from the test execution software, the test remote online execution can be realized by combining a communication protocol developed specifically and a server, the development workload is small, the realization is easy, and the Dataskets technology of NI company is realized by the method.
