[0048] Please see Figure 1 , Figure 1 This is a schematic flowchart illustrating a general testing method for automated testing equipment provided in an embodiment of the present invention. This general testing method for automated testing equipment is applied to automated testing equipment, enabling the addition of new test items or modification of existing code with minimal changes, avoiding omissions and reducing duplicate code.

[0049] Figure 1 This is a flowchart illustrating the general testing method for automated testing equipment provided in this embodiment of the invention. Figure 1 As shown, the method includes the following steps S110 to S150.

[0050] S110. Classify the test items supported by the automated testing equipment to obtain the classification results.

[0051] In this embodiment, the classification results include FlowTest, CommunicationTest, etc.

[0052] Specifically, the test items supported by the automated testing equipment are classified, and the common information of test items of the same type is placed in the base class. Each test item inherits from the parent class to obtain the classification result.

[0053] The automated testing equipment supports various test items, categorizing them and placing common information for test items of the same type in a base class, with each test item inheriting from the parent class. For example, if the equipment supports pairwise interaction testing, aggregation testing, and serial port testing, since pairwise interaction testing and aggregation testing belong to stream testing, and serial port testing belongs to communication testing, then there can be two base classes: a stream testing class and a communication testing class. Pairwise interaction testing and aggregation testing can inherit from the stream testing class, and serial port testing can inherit from the communication testing class.

[0054] In this way, the common parts are extracted as the base class. When various test items are added later, only a new subclass needs to be added, which stores the attributes not included in the base class.

[0055] When new test items are added in this embodiment, only the unique test attributes need to be added.

[0056] S120. Divide each type of test item in the classification results into two base classes.

[0057] In this embodiment, the two base classes include a streaming test attribute base class and a streaming test process base class.

[0058] Specifically, a base class for flow test properties (FlowTestSetting) is created, which contains common test properties for all flow tests; a base class for flow test processes (FlowTestItem) is created, which is compatible with test processes for all flow tests.

[0059] S130. Divide each type of test item in the classification results into attribute class and process class, and inherit the corresponding parent class.

[0060] In one embodiment, please refer to Figure 2 The above-mentioned step S130 may include steps S131 to S132.

[0061] S131. Divide each type of test item in the classification results into attribute class and process class;

[0062] S132. Inherit the test items of the attribute class from the flow test attribute base class, and inherit the test items of the process class from the flow test process base class.

[0063] Specifically, create an attribute class: AllcustomSetting, which inherits from FlowTestSetting, containing the test attributes required for pairwise interactions other than those in FlowTestSetting; create a process class: AllcustomItem, which inherits from FlowTestItem. For a given test process in FlowTestItem, if different test items have different test methods, these methods are overridden in AllcustomItem. For example, if the test results need to be validated, the validation interface in FlowTestItem provides a general validation method. If the validation methods for pairwise interactions differ, then the validation interface is overridden in AllcustomItem.

[0064] Each test is divided into two main categories: test attribute settings and test process items. For example, the FlowTest class can be divided into the FlowTestSetting class (flow test attribute class) and the FlowTestItem class (flow test process class). The FlowTestSetting class contains the test attributes common to all flow tests, while the FlowTestItem class contains the common test processes for flow tests.

[0065] Similarly, pairwise interaction tests are also divided into pairwise interaction attribute classes (Class testSetting, inheriting from FlowTestSetting) and pairwise interaction process classes (Class testItem, inheriting from FlowTestItem). If some processes in FlowTestItem handle different test items differently, they should be overridden in testItem. If a pairwise interaction attribute is not present in FlowTestSetting, it should be added in testSetting.

[0066] Modifying common attributes requires only one file. When adding a new test item, the file content only needs to include the new content. Each test item is divided into two main categories: test attributes and processes, which is intuitive and easy to maintain.

[0067] This embodiment minimizes the amount of modification required when changing test items and maintains a clear structural hierarchy.

[0068] S140, setting parameters for the two base classes and the basic interface for test items.

[0069] In one embodiment, please refer to Figure 3 The above-mentioned step S140 may include steps S141 to S142.

[0070] S141. Set the base class of the streaming test process to generic, and set the parameters of the base class of the streaming test process to the corresponding attribute classes;

[0071] S142. Set the basic interface for the test item.

[0072] Please see Figure 4 Set FlowTestItem to generic type and set the parameter to the corresponding property class, such as: classFlowTestItem <t>:TestItem <t>The `where T:FlowTestSetting` directive associates the attribute class with the flow class, such as a pairwise interaction: `class AllcustomItem:FlowTestItem`. <allcustomsetting>;TestItem <t>This is the basic interface for test items: Initialize(), Run(T setting) to run the test, and Stop() to stop the test. `setting` is the property class for the test item, such as AllCustomSetting.

[0073] S150, Construct function parameters for the process class.

[0074] In this embodiment, the parameters of the AllcustomItem constructor can be some basic test properties, such as AllCustomTest(TestItemOption option), which is the entry property for initializing the test item, while AllCustomSetting is equivalent to a condition property.

[0075] This embodiment allows for minimal changes when adding new test items or modifying existing code, avoiding omissions and reducing code duplication. A clear hierarchical structure and categorization of test items improve code maintainability and readability, facilitating subsequent management.

[0076] For a concrete example: Automated testing equipment can perform pairwise interaction tests, convergence tests, and serial port tests. This leads to two categories: flow testing and communication testing. Flow testing has two files: `FlowTestItem` (basic test flow) and `FlowTestParameters` (basic test attributes). Communication testing also has two files: `CommunicationTestItem` (basic test flow) and `CommunicationTestParameters` (basic test attributes). Pairwise interaction tests also have two files: `AllCustomSetting` (test attributes unique to basic test attributes) and `AllCustomTest` (parts of the basic test flow that need to be overridden). The parent class of `AllCustomSetting` is `FlowTestParameters`, and the parent class of `AllCustomTest` is `FlowTestItem`. Similarly, serial port testing has two files: `SerialPortSetting` (test attributes unique to basic test attributes) and `SerialPortTest` (parts of the basic test flow that need to be overridden). The parent class of `SerialPortSetting` is `CommunicationTestParameters`, and the parent class of `SerialPortTest` is `CommunicationTestItem`.

[0077] The aforementioned general testing method for automated testing equipment categorizes the test items supported by the automated testing equipment, defining attribute classes and process classes, and inheriting from the corresponding parent class, i.e., the base class. When adding various test items later, only a new subclass needs to be added, containing attributes not included in the base class. Modifications to common attributes only require modifying a single file. When adding a new test item, the file content only needs to include the new content. Each test item is divided into two main categories: test attributes and processes, which is intuitive and easy to maintain. Adding new test items or modifying existing code allows for minimal changes, avoiding omissions and reducing code duplication.

[0081] In one embodiment, such as Figure 6 As shown, the second classification unit 302 includes a test item classification subunit 3021 and an inheritance subunit 3022.
