It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The invention provides an automatic test method of reader interface specification, as shown in figure 1, a reader is used for reading and processing data, and in the test process, the method is mainly used for judging whether an interface of the reader can normally receive and process the data, according to the application interface specification of automotive electronic identification read-write equipment, the data transmitted by the reader comprises a message head and a message body, the composition of the message head is fixed, but the message body comprises a plurality of parameters, so that the types of the message body comprise more than 40, the types of the parameters comprise simple parameters, structural parameters and identifiers, and the number of the structural parameters is more than 120. And when the parameters are read and tested, each parameter corresponds to a set key parameter.
Therefore, data in the specification of the application interface of the electronic identification reading and writing equipment of the motor vehicle are read, the test rules of all message bodies at the position and key parameters corresponding to the parameters are extracted, and an xml file is generated. Inputting the mode and step of reader and receiving mode when the test rule is the message body test; the key parameters are used for detecting whether the data interface can normally identify data and outputting the read data according to the standard, and the test rule and the key parameters are set according to the requirements of national standard standards.
The xml files are grouped according to the types of the message bodies, and each group comprises the test rules of the message bodies, the key parameters including all the parameters and the corresponding accurate output. Extracting all groups of the xml file to generate a plurality of data interfaces (each group is a data interface), extracting information in the data interfaces in the xml file and converting the information into a Python class, generating an interface list which is convenient to call according to the Python class, and storing the interface list into a database. When the reader is tested, different data interfaces can be conveniently and automatically called according to the test function (different message body types used by different functions are different, and the called data interfaces are also different).
Each message body type can correspond to a plurality of test functions, and different test functions correspond to different test rules. For example: the identification function is whether the reader can identify the message or not, and the access function is whether the reader can access the parameters at the fixed position in the message or not.
Therefore, when the reader is tested, the reader is connected with the testing equipment, the function to be tested is input into the testing equipment, the testing device traverses all interface information in the interface list according to the received testing function, extracts all information in the data interface meeting the testing function according to the testing rule corresponding to the testing function, generates a plurality of messages, and generates message data for testing the function by combining all messages meeting the function.
Each parameter corresponds to a plurality of fixed key parameters, and each message body can contain a large number of square parameters, so that the key parameters to be tested in one message are too large. The reader is used for transmission and data processing, and each time the reader tests one function, all the key parameters included in the message body need to be tested once, so that a large amount of time is spent, and the research and development period is increased.
In order to shorten the detection time, a parameter merging strategy is arranged in the test equipment. The merging strategy is used for merging the key parameters corresponding to a plurality of different parameters into one test parameter, so that the number of the test parameters in the message is reduced, the test time of the reader is shortened, all the key parameters are ensured to be detected, and the test accuracy is not influenced.

According to the type of the message body, different types of key parameters are superposed in the message body as much as possible to generate a test input, and meanwhile, the test input is correspondingly combined and accurately output to generate a test output. And generating a message by testing input, testing output and testing rules, combining other key parameters by using the same method to generate a message, and generating message data by combining all messages in a message body. Thus, a function includes multiple message data, and each message data includes a combination of all key parameters.
The test device generates a plurality of message data according to the functions, selects the message data, sequentially inputs the messages in the message data into the reader according to the test rules, and the test equipment receives and stores the feedback data given by the reader and compares the feedback data with the test output for judging whether the interface is accurate and complete. Example (c): whether the reader deletes the character at the input data setting position or not is judged, and whether the reader can realize the function of deleting the character or not is judged.
The testing steps of the testing device comprise: the test function is received, the test rule is selected according to the test function (the same test function can comprise a plurality of test rules), the test function corresponds to a plurality of test rules, a plurality of test functions can be simultaneously input, and the simultaneous test of a plurality of functions of the reader is facilitated. Acquiring an interface list according to the test rule, calling a corresponding data interface, judging whether the corresponding data interface is called in the interface list, if not, finishing the test, and if so, generating a plurality of message data according to the test rule;
obtaining a message, judging whether the message is obtained or not, returning to the step of calling a corresponding data interface if the message is obtained, issuing and storing the message, judging whether the issuing is successful or not, returning to the step of judging whether the message is obtained or not, receiving feedback data of a reader, comparing and analyzing the feedback data with test output, storing the feedback data and an analysis result, and then continuing to obtain the message. And traversing all message data by using the same method, and storing the test result to finish the test of the reader.
