The man-machine interaction interface can be designed with options of starting, pausing, continuing, ending and the like, so that one-key starting test and other user requirements are realized, a corresponding test data header can be automatically generated according to the selection of the test items, and the test data is displayed in the test data header. In addition, the man-machine interaction interface can also be designed with a test result button which can be directly positioned to the test data stored after the test is finished.
And the control layer 2 is used for storing test information according to the test command, dynamically creating a test item by utilizing reflection and adding the test item into the test case pool, binding the event of the test case layer 3 and the event processing function of the control layer 2 in an asynchronous mode, transmitting the connection relation of the test instrument and the connection relation of the tested equipment to the test item, starting an automatic test thread and starting to sequentially execute the test item in the test case pool.
The control layer 2 is the core of the automated testing framework, and connects the interface layer 1, the test case layer 3, the instrument driving layer 4 and the interface control layer 5. When a user clicks a start button on the human-computer interaction interface, the interface layer 1 transmits the test information to the control layer 2, and the control layer 2 stores the test information. After the control layer 2 finishes the preparation work, an automatic test thread is started, the control layer 2 displays the test data on the human-computer interaction interface in real time, and the status bar information of the interface layer 1 can be updated.
And the test case layer 3 is used for running a case execution method to call the instrument driving layer 4 and the interface control layer 5 in an automatic test thread and automatically storing test data generated in the test process in a result document, wherein the test case layer 3 triggers an event processing function of the control layer 2 when generating data in the test process.

Because the test instruments, the judgment standards, the case execution methods, the interfaces and the like used by different test items are different, but each test item relates to the operations, a test case base class can be designed for the test case layer 3, wherein the test case base class comprises a case execution method, parameters needing to be transmitted, test instrument objects, entrustment events needing to transmit test data to the control layer 2 or the interface layer 1 and the like, each test item designs a C # class, the class is derived from the test case base class, the class has all member fields and functions of the base class, and the realization codes of the functions are rewritten in the definition of the derived class.
In the present embodiment, the result document may be Excel, Word, or text document.
And the instrument driving layer 4 is used for reading an instrument command according to the connection relation of the test instrument and the instrument to carry out program control on the test instrument when the test items in the test case pool are executed so as to realize connection and disconnection of the test instrument and the reading of test data.
Wherein the instrument commands may be encapsulated using XML files. Different instrument and meter commands are packaged by using XML files, and when test instruments and meters of different manufacturers are replaced, only the XML files need to be modified or replaced.
