Problems solved by technology

[0014] The purpose of the present invention is to provide an automatic test method for relay protection devices based on feature words to solve the problem of using automatic test systems to test protection devices at present. For devices of the same type, test cases can be used repeatedly, but for different types Although the test business is the same, the test cases cannot be used universally, and the writing, management and maintenance of test cases require a lot of effort. The automatic test system built based on this method has poor adaptability.

Embodiment 1

[0044] Such as figure 2 As shown, the instantiation is completed before all tests, and this process is carried out in the following steps:

[0045] A) the feature word mapping module calls one (or more) test case templates in the test case template storehouse containing the feature words;

[0046] B) the test case template of calling is mapped to the test case containing the information point of the device under test by the feature word mapping module (forming a test case library containing the information point of the device under test);

[0047] c) The automatic test execution module calls the test case after the above mapping is completed;

[0048] d) The automatic test execution module executes the test case according to the traditional test method;

[0049] e) The automatic test execution module judges the test result according to the feedback information of the device under test.

[0050] Compared with the traditional test system, the above process adds a feature wor...

Embodiment 2

[0052] Such as image 3 , a single test object is instantiated one by one before testing, the difference from Example 1 is only in the first few steps:

[0053] a) call the test case template in the test case template library;

[0054] b) load the feature word mapping module in the program initialization, and the feature word mapping module maps the called test case template to the test case containing the information points of the device under test, and completes the instantiation;

[0055] c) The automatic test execution module executes the test cases... (omitted later).

[0056] The characteristic of the above process is that the mapping of test case feature words to information points is completed when the program is initialized.

Abstract

The invention relates to an automatic testing method and device for a relay protection device based on a feature word, which is characterized in that the test case is generated for a specific test business, unlike the prior art, where the test case must face a specific device. By introducing feature words, test case templates based on feature words for specific test services can be compiled. When testing a specific device, the test case template is instantiated according to the mapping relationship between the information points of the device and the feature words in the test case template. , to generate test cases for specific test services, which are suitable for the test of the protection device. This method can significantly reduce the workload of writing test cases and quickly complete the test work of the new device under test. This method maximizes the reuse of test cases and improves the test efficiency of the automatic test system.

Description

technical field [0001] The invention relates to the field of automatic testing of relay protection devices, in particular to an automatic testing method based on characteristic words. Background technique [0002] The existing automatic test system of relay protection device is as attached figure 1 As shown, it includes: tester client; tester; automatic test execution module; input and output card; protection device. [0003] In conventional testing, the tester, the BIO card and the device under test constitute the main test circuit, and the output current and voltage of the tester are sent to the device under test through the BIN / BOUT card. The tester client and the automatic test execution module constitute the software test control part, and the input conditions of the protection device come from the tester. The control of the tester is completed by the client side of the tester through test cases. The tester has a test report output. During the test, the automatic test...
