[0022] Embodiment 1

[0023] Figure 1 It is a flowchart of a client testing method in an embodiment of the present invention. This embodiment is applicable to the case where an OPC client is tested through an OPC server. The client testing method of this embodiment is executed by a target server. In this embodiment, the target server may be an OPC server used to test an OPC client. The target server is connected to a client to be tested, wherein the client to be tested may be an OPC client to be tested, for example, an OPCDA (OPC Data Access) client, an OPC UA (OPC Unified Architecture) client, or an OPC AE (OPC Alarms & Events) client. In this embodiment, the target server includes: a data reading and writing module. Among them, the data reading and writing module may be a data reading and writing module in the OPC server. As Figure 1 As shown, the method specifically comprises the following steps:

[0024] S101. Obtain an expected information set from a test case through a data reading and writing module, obtain a real-time value of a subscription number from a database, compare the real-time value of the subscription number with the expected information set, and obtain a test result.

[0025] The expected information set includes: an expected writing object, an expected writing value, and an expected writing cycle.

[0026] The real-time value of the subscription number is the real-time value of the number of the target server subscribed by the client to be tested.

[0027] The test case may be a test case written by a user and used to test an OPC client to be tested through an OPC server.

[0028] It should be noted that the test result may be a result obtained after testing the client to be tested. Exemplarily, the test result may be that the client to be tested passes the test. In other embodiments, the test result may also be that the client to be tested fails the test.

[0029] Specifically, the data reading and writing module in the target server obtains the expected information set from the test case, and then obtains the real-time value of the subscription target server bit number stored by the client to be tested from the database, compares the real-time value of the subscription bit number with the expected information set, and determines whether the test of the client to be tested passes.

[0030] The embodiment of the present invention designs a target server, connects the target server to the client to be tested, and includes a data reading and writing module. The target server obtains the expected information set from the test case through the data reading and writing module, and then obtains the real-time value of the subscription bit number from the database, compares the real-time value of the subscription bit number with the expected information set, and obtains the test result. Through the technical solution of the present invention, it is possible to complete the test of the OPC client conveniently and quickly without the help of a third-party server.

[0031] Optionally, before obtaining the real-time value of the subscription number from the database through the data reading and writing module, it also includes:

[0032] Through the data reading and writing module, in response to the bit number acquisition request sent by the client to be tested, the bit number set corresponding to the bit number acquisition request is sent to the client to be tested, and the subscription bit number information sent by the client to be tested is received, and the subscription bit number information includes the unchanged bit number information and the changed bit number information, and the unchanged bit number information is sent to the OPC service module.

[0033] The bit number acquisition request may be a request sent by the client to be tested to the target server to acquire the bit number in the target server, and the bit number set may be a set of bit numbers sent by the target server to the client to be tested according to the bit number acquisition request.

[0034] In this embodiment, the subscription number information may be information related to the number subscribed by the client to be tested to the target server, and the subscription number information includes constant number information and variable number information. The constant number information may refer to information related to the number whose real-time value will not change, and the variable number information may refer to information related to the number whose real-time value will change.

[0035] In actual operation, after the client to be tested establishes a connection with the target server, the client to be tested sends a bit number acquisition request to the target server, and the data reading and writing module in the target server sends the bit number set corresponding to the bit number acquisition request to the client to be tested. For example, if the client to be tested needs to obtain all bit numbers of the target server, the data reading and writing module in the target server can form a bit number set of all bit numbers and send it to the client to be tested.

[0036] Afterwards, the client to be tested selects a part of the bit numbers in the received bit number set for subscription, and returns the subscription bit number information to the target server. The subscription bit numbers selected in the client to be tested may include unchanged bit numbers and variable bit numbers. The specific bit number change cycle can be set from the test case. For example, there are 80 bit numbers in the bit number combination, of which 40 bit numbers are subscribed, and the 40 bit numbers include 30 unchanged bit numbers and 10 variable bit numbers. After receiving the unchanged bit number information, the target server sends the unchanged bit number information to the OPC service module, so that the OPC server module can write values ​​to these unchanged bit numbers.

[0037] Through the OPC service module, the constant bit number information sent by the data read-write module is received, and the constant bit number is written according to the constant bit number information to obtain the real-time value corresponding to the constant bit number, and the real-time value corresponding to the changing bit number and the real-time value corresponding to the constant bit number are fed back to the data read-write module, so that the data read-write module sends the real-time value corresponding to the changing bit number and the real-time value corresponding to the constant bit number to the client to be tested.

[0038] Among them, the real-time value corresponding to the unchanged bit number can be the value after the unchanged bit number is changed after the write operation is performed on the unchanged bit number. For example, if the unchanged bit number is 001 before writing the value and 002 after writing the value, then the real-time value of the unchanged bit number is 002.

[0039] Specifically, after the target server performs the write operation, it sends the real-time value of the changed bit number and the real-time value of the unchanged bit number to the client to be tested. After receiving the real-time value, the client to be tested stores the fact values ​​in the database.

[0040] Optionally, the target server also includes: a configuration module.

[0041] Before obtaining the real-time value of the subscription number from the database through the data reading and writing module, it also includes:

[0042] The configuration information is obtained from the test case through the configuration module, and configuration modeling is performed according to the configuration information to obtain a configuration model.

[0043] The configuration information includes: parameter information, IP address, port information, login information, expected value of change bit number and change cycle.

[0044] The configuration model may be a model obtained after the configuration module performs configuration modeling according to the acquired configuration information.

[0045] Specifically, the configuration module of the target server obtains the configuration data defined by the test case, and the configuration module performs configuration modeling according to the obtained data to obtain the configuration model.

[0046] Through the OPC service module, the configuration model is read to complete the server operation.

[0047] Specifically, the OPC service module starts and reads the configuration model established by the configuration module to complete the server operation.

[0048] Optionally, the client testing method also includes:

[0049] Through the data reading and writing module, the expected alarm events are obtained from the test cases, the actual data of the alarm events are obtained from the database, the actual data of the alarm events are compared with the expected alarm events, and the test results are obtained.

[0050] The expected alarm event may be an alarm or event that the target server set in the test case expects to generate. The actual data of the alarm event is the alarm or event actually generated by the target server. The actual data of the alarm event is stored in the database by the client to be tested.

[0051] Specifically, the data reading and writing module in the target server obtains the expected alarm event from the test case, and then obtains the actual data of the alarm event stored in the client to be tested from the database, compares the actual data of the alarm event with the expected alarm event, and determines whether the test of the client to be tested passes.

[0052] Optionally, after obtaining the expected alarm event from the test case through the data reading and writing module, it also includes:

[0053] Generate actual data of alarm events according to the expected alarm events, and send the actual data of alarm events to the client to be tested through the data reading and writing module.

[0054] During the actual operation, after the target server obtains the expected alarm event from the test case, it generates the actual data of the alarm event according to the expected alarm event, and sends the actual data of the alarm event to the client to be tested through the data reading and writing module. The client to be tested stores the actual data of the alarm event in the database.

[0055] As an exemplary description of an embodiment of the present invention, Figure 2 FIG. 1 is a structural diagram of an exemplary client testing method in an embodiment of the present invention. Figure 2 As shown, with the OPC server as the target server, the main operations of the client test method can be described as:

[0056] First, the configuration module of the OPC server reads the configuration data defined in the test case, and the configuration module performs configuration modeling based on the acquired configuration data; secondly, the OPC service module starts and reads the configuration model established by the configuration module to complete the server operation; then, when there is a read and write demand, the OPC server reads the read and write demand in the test case, and the data read and write module of the OPC server is responsible for reading the expected write object, expected write value and expected write cycle. The OPC service module requests the data read and write module to read and write data, and transmits the information to the OPC service module. After completing the subscription and read and write operations, the OPC service module returns the actual data to the data read and write module. The data read and write module sends the actual data to the client to be tested, so that the client to be tested stores the actual data in the database. The data read and write module obtains the actual data from the database, and then compares the parameters passed in by the test case with the actual data obtained from the database to determine the correctness of the data reading and writing.

[0057] The technical solution of the embodiment of the present invention is to connect the target server with the client to be tested by designing a target server. The target server includes: a configuration module, an OPC service module and a data reading and writing module. Through the configuration module, parameter information, IP address, port information, login information, expected value of change bit number and change cycle and other configuration information are obtained from the test case, and configuration modeling is performed according to the configuration information to obtain a configuration model. Through the OPC service module, the configuration model is read to complete the server operation. Afterwards, through the data reading and writing module, in response to the bit number acquisition request sent by the client to be tested, the bit number set corresponding to the bit number acquisition request is sent to the client to be tested, and the subscription bit number information sent by the client to be tested is received, the subscription bit number information includes the unchanged bit number information and the change bit number information, and the unchanged bit number information is sent to the OPC service module, and the unchanged bit number information sent by the data reading and writing module is received through the OPC service module, and the unchanged bit number is written to the unchanged bit number according to the unchanged bit number information, and the real-time value corresponding to the unchanged bit number is obtained, and the real-time value corresponding to the change bit number and the real-time value corresponding to the unchanged bit number are fed back to the data reading and writing module, so that the data reading and writing module sends the real-time value corresponding to the change bit number and the real-time value corresponding to the unchanged bit number to the client to be tested, and the client to be tested stores the real-time value of the subscription bit number in the database, and obtains the expected information set from the test case through the data reading and writing module, obtains the real-time value of the subscription bit number from the database, and compares the real-time value of the subscription bit number with the expected information set to obtain the test result. Through the technical scheme of the present invention, it is possible to achieve the test of the OPC client conveniently and quickly without the help of a third-party server.

[0059] Figure 3 is a structural diagram of another exemplary client testing method in an embodiment of the present invention, which is applicable to the case where an OPC DA client, an OPC UA client, and an OPC AE client are tested through an OPC server. Figure 3 As shown, the client testing method specifically includes the following steps:

[0060] The OPC server obtains configuration information (parameter information, IP address, port information, login information, expected value of change bit number, change cycle) from the test case, and performs configuration modeling based on the configuration information to obtain the configuration model, read the configuration model, and complete the server operation. The OPC DA client, OPC UA client, and OPC AE client to be tested establish a connection with the OPC server. Then start the test:

[0061] The OPC server obtains the expected write object, expected write value, and expected write value cycle from the test case. The OPC DA client and OPC UA client to be tested obtain all the bit numbers of the OPC DA server and OPC UA server respectively, and after determining the subscription bit number, send the unchanged bit number and the changed bit number in the subscription bit number to the OPC server. After the OPC server performs the write operation, it sends the real-time value of the subscription bit number to the OPC DA client and OPC UA client to be tested. The OPC DA client and OPC UA client to be tested store the real-time value of the subscription bit number in the database. The OPC server obtains the real-time value of the subscription bit number from the database, and compares it with the expected write object, expected write value, and expected write value cycle obtained from the test case to obtain the test result.

[0062] The OPC server obtains the expected alarms and events from the test case, and generates the actual data of the alarms and events according to the expected alarms and events, and then sends the actual data of the alarms and events to the OPC AE client to be tested, and the OPC AE client to be tested stores the received actual data of the alarms and events in the database. The OPC server obtains the actual data of the alarms and events from the database, and compares it with the expected alarms and events obtained from the test case to obtain the test results.

[0063] In the technical solution of the embodiment of the present invention, the OPC server obtains the expected configuration content and expected server information in the test case, configures and runs the OPC service, and quickly and conveniently completes the construction of multiple OPC servers. Various OPC clients connect to the corresponding OPC server, and complete the OPC client test by comparing the expected data in the test case with the actual data obtained from the database. The read-write module of the OPC server completes the bit number write operation by obtaining the expected write value object, write value, cycle and other information in the test case, solving the problem of the open source server client's restriction on the bit number write value.
