These embodiments are provided to disclose the present invention in detail and completely, and to fully convey the scope of the present invention to those skilled in the art.

In addition, it can be understood that the terms defined in the commonly used dictionary should be understood to have the same meaning as the context of their related fields, and should not be understood as idealized or overly formal meanings.

[0016] According to the first aspect of the present application, a method 100 for testing an electricity meter software is provided. Referring to Figure 1 as shown, the method 100 includes:

[0017] S102: According to the software programming standard of the electric energy meter and the system interface standard of the electric energy meter, in the Windows environment, implement each interface of the electric energy meter software APP, and generate an executable program for the virtual operation of the electric energy meter software;

[0018] S104: In the virtual operation environment, call the interface function to record the electric energy meter data, and check whether the input parameters of each interface of the electric energy meter software APP and the business data and technical means called meet the standards according to the electric energy meter data;

[0019] S106: When the executable program for the virtual operation of the electric energy meter software is initialized, monitor and record the memory size applied by the executable program for the virtual operation of the electric energy meter software; when the executable program for the virtual operation of the electric energy meter software is running normally, measure the time length of the executable program for the virtual operation of the electric energy meter software occupying the CPU resources once through the clock slice provided by the system kernel, count the number of times the APP calls the system within one second and record it.

[0020] Specifically, simulate the devices and services required for the operation of the electric energy meter software APP through WINDOS application programming, virtualize the operation environment of the electric energy meter software APP, and run the test environment in the form of a third party. Embed interface test functions in the simulated operation environment, record and analyze the data when the software APP calls the system interface, trace the on-site data when the electric energy meter software APP runs abnormally, monitor the consumption of system resources by the APP, test the performance indicators of the APP, and output the test data in an appropriate form:

[0021] Step 1:

[0022] According to the programming standard of the electric energy meter software APP, the system interface standard, etc., program under WINDOS, and implement each interface of the electric energy meter software APP with WINDOS resources to generate an executable program for the virtual operation of the electric energy meter APP software.

[0023] Step 2:

[0024] Design and develop a hook function for the APP interface program call in the virtual operation environment, record the scene when the interface function is called, and the hook function specifically records the context register group and the data values of the working register group at the entrance of the current function; judge the compliance of the input parameters of the APP interface and the called business and technology, and record the input parameter data values when they do not meet the requirements, and display and throw a call error to the system, prompting the specific error type and reason.

[0025] Step 3:

[0026] Design a monitoring function for the initialization and operation of the APP. When the APP is initialized, monitor and record the size of the memory space applied for by the APP, and determine whether the applied memory size exceeds the system-set value. If it exceeds the set value, record and prompt an error. During the normal operation of the APP, measure and calibrate the length of time the APP occupies the CPU resources once through the clock slices provided by the system kernel, count the number of times the APP calls the system within one second, and record it. By designing a memory out-of-bounds monitoring program, record memory exception information. When memory exceptions such as accessing memory that has been released on the heap, accessing the heap buffer overflow, accessing the stack buffer overflow, accessing the global buffer overflow, accessing memory that has been released on the stack, using stack objects beyond the defined range, and memory leakage occur, immediately stop running, record the memory address information, and record the current context working register group and the working register group.

[0027] Thus, through the APP test tool applied to design and development, the third-party and interchangeability tests of the IoT meter APP are assisted to be realized.
