[0049] This application provides a method and apparatus for instantiating test cases for remote motors, which can improve the testing efficiency of remote motors.

[0050] In this embodiment, the method for instantiating test cases of the remote control machine can be implemented in the system, on the server, or on the terminal, without any specific limitation.

[0051] Please see Figure 1 This application uses system examples for description. One embodiment of the method for instantiating test cases for remote motors in this application includes:

[0052] 101. The system obtains the configuration parameters of the remote control unit and the identification information of the test cases;

[0053] In this embodiment, the system obtains the configuration parameters of the remote motor, including the number of participating devices, the remote transmission area selection method, the number of triggering devices, and the number of triggering test points. The remote transmission area selection method may include randomly selecting the remote transmission area or specifying the remote transmission area. The identification information of the test case includes the test case ID.

[0054] In addition, the test cases in this embodiment are special scenarios, specifying the information corresponding to the test scenario. The scenario is a clear and sequential system operation trajectory, which has a wide range of applications in the software life cycle. The expression of test scenarios includes static ones. Static expressions can be defined in the form of tables, etc., to organize the system and provide conditional data for the automatic generation of test cases in the subsequent dynamic expressions, thereby realizing the automatic generation of test cases.

[0055] 102. The system matches at least one identical first abstract template under the corresponding identifier information based on the configuration parameters;

[0056] In this embodiment, the configuration parameter refers to the number of participating devices. The system clones multiple identical first abstract templates under the corresponding test case ID according to the number of participating devices. These first abstract templates are identical sub-abstract templates. In addition, a shallow cloning method is used in the process of cloning sub-abstract templates, that is, variables of the configuration parameter type are directly assigned values.

[0057] 103. The system combines the first abstract template to generate the second abstract template;

[0058] In this embodiment, the system first determines whether the number of test case IDs, the number of participating devices, the method of selecting the remote transmission area, the number of triggering devices, and the number of triggering test points are greater than i, where i is the length of the test case. The path of the test case does not contain loop states, meaning the path and the test case are consistent. The structure generated by the test case is a test set, which is a finite set of test cases. When the number of configuration parameters is greater than i, identical sub-abstract templates are cloned. When the maximum number is reached, all sub-abstract templates are concatenated to generate a second abstract template, which is the final abstract template file (xml).

[0059] 104. Select the second test point from the instantiated test point set and map the second test point to the second abstract template to obtain the test case scheme of the remote motor. The instantiated test point set is accurately obtained by loading the SCD model file.

[0060] In this embodiment, the system first finds all remote transmission areas that meet the conditions, have imported RCD and SCD, and have generated instantiated measurement point records (i.e., containing actual information such as specific IED, dataset, and reference).<remote_no> A set, wherein the condition that satisfies the configuration parameter satisfies the instantiation mapping condition;

[0061] In the remote transmission area that meets the conditions<remote_no> The system uses a for loop within the set to iterate and parse the remote_N.xml file, which contains all instantiated test point records, based on the number of triggering devices (IEDs) and the number of trigger test points. It then automatically selects test points according to a selection algorithm, finding all second test points that meet the conditions, where the second test points are those that satisfy the abstract template environment. Finally, based on these second test points, test cases are automatically generated with a single click. This allows for automated testing of the subsequent functional performance of the intelligent remote actuator, which can be loaded and used at any time, reducing the workload of testers and effectively improving the testing efficiency of the remote actuator.

[0062] Please see Figure 2 The embodiments of this application use system examples for description. Another embodiment of the method for instantiating test cases for remote motors in this application includes:

[0063] 201. The system obtains the configuration parameters of the remote control unit and the identification information of the test cases;

[0064] Step 201 in this embodiment is similar to step 101 in the previous embodiment, and is not limited here.

[0065] 202. The system matches the corresponding abstract template XML format from the abstract template library based on the identification information. The abstract template library is designed based on the test cases.

[0066] In this embodiment, the system designs a unified abstract sub-template XML format based on different test cases. The format includes a general format and a special format, as detailed below:

[0067] 1. The general format is applicable to test cases including: three-phase combined signal, SOE signal testing, remote control testing, and remote adjustment testing. Format content representation:

[0068]

[0069] 2. Test cases applicable to this special format include: avalanche simulation tests and site-wide load loss tests. Format content representation:

[0070]

[0071]

[0072] Test cases for which this special format applies also include: Motion Unification Configuration Tool checks. Format content representation:

[0073]

[0074] It should be noted that the above format... <function>Generally includes <param> Parameter nodes and <group>Nodes, such as timeouts for parameters required by this test case; among which <group>A node is information about a certain remote transmission area, and then its child items... <data>These are certain measurement points and their attributes within this remote transmission area. <data>The information is abstract and not bound to any actual device IED information.

[0075] In addition, the abstract template repository is composed of abstract sub-templates, which are designed according to the test case ID. The large abstract template repository TestCases.xml can be extracted and used later. In this embodiment, the test case abstract template repository has traceable test plan data and can meet the test case requirements of different scenarios.

[0076] 203. The system constructs at least one identical first abstract template under the corresponding identification information based on the configuration parameters;

[0077] 204. The system combines the first abstract template to generate the second abstract template;

[0078] Steps 203 to 204 in this embodiment are similar to steps 102 to 103 in the previous embodiment, and will not be described again here.

[0079] 205. By setting the attribute category features of the first measurement point under the remote transmission area of ​​the remote motor, the instantiation mapping of the first measurement point is performed, and the instantiation measurement point set of the remote transmission area is generated.

[0080] The system sets the attribute category features of the first measurement point under remote_no for each remote transmission zone, completes the instantiation mapping of all measurement points, and generates a collection of instantiated measurement point record files remote_1.xml, remote_2.xml, ..., remote_N.xml for all remote transmission zones. Specific settings are as follows:

[0081] Import the remote control configuration description file (RCD) and the substation SCD model file under each remote control zone. The SCD model file is a type of model file specified in the IEC 61850 standard, used to describe the information of the primary and secondary equipment of the entire substation. Generate a list of all remote signaling, telemetry, and remote control under this remote control configuration. The list should include the actual information such as the specific 61850 device IED, dataset, and 61850 leaf reference, and provide editable measurement point attribute categories.

[0082] Add one attribute column to the remote message list<my_class> (Remote signaling category yxclass): 0 - Basic remote signaling class (default); 1 - Communication status virtual signal class; 2 - Formula calculation generated quantity class; 3 - Total accident signal. One attribute column has been added to the telemetry list.<my_class> (Telemetry Category ycclass): 0--Basic Telemetry; 1--Combined Calculation Class; 2--Other Virtual Telemetry. Add one attribute column to the remote control list.<my_class> (Remote control category ykclass): 0-Remote control switch knife switch type (default value); 1-Remote control pressure plate type; 2-Remote adjustment gear type; 3-Reset remote control type.

[0083] 206. System traverses and parses the instantiated set of measurement points;

[0084] In this embodiment, the system operates in a remote transmission area that meets certain conditions.<remote_no> The collection uses a for loop to iterate and parse the remote_N.xml file, which contains all instantiated measurement point records, based on the number of triggering devices (IEDs) and the number of triggering measurement points.

[0085] 207. Select the second measurement point from the traversed set of instantiated measurement points using the point selection algorithm system;

[0086] The system internally binds based on different test cases. <data>A node expansion mechanism is established, along with corresponding node selection algorithms. For example: SOE signal testing should satisfy yxclass = 0; remote adjustment testing should satisfy ykclass = 2; total fault signal should satisfy yxclass = 3; three-phase combined signal should satisfy yxclass = 2 && the formula expression contains no less than two "|".

[0087] 208. The system generates test case schemes for the telemotor by improving the node attributes of the second abstract template.

[0088] After the instantiation of the test point set is completed in the above steps, the system expands and improves all node attributes under the final abstract template, generating the final remote_1.xml, remote_2.xml, ..., remote_N.xml. This invention simplifies the test case editing process by using an abstract mapping mechanism to generate test case schemes, avoiding the inefficiency, error-proneness, and lack of reproducibility associated with manually generating test cases by software testers, which increases the overall cost of software development.
