Method and device for generating test case

Abstract

The invention discloses a method and a device for generating a test case, which are used for increasing the coverage on a core test scene so as to improve the efficiency for controlling fault leakage. The method comprises the following steps: combining test factors contained in a test class, and generating a plurality of test factor combinations; for each test factor combination, determining the priority of the test factor combination according to the attribute of each test factor in the test factor combination, and classifying the test factor combination into a set of the corresponding priority according to the priority of the test factor combination; selecting a corresponding quantity of test factor combinations from the set according to the test phase, the test coverage or the task cycle of the current test; and generating a test case based on the selected test factor combinations. By using the technical scheme, the coverage on a core test scene can be increased, and the efficiency for controlling fault leakage can be improved.

Description

technical field [0001] The invention relates to the field of testing, in particular to a method and device for generating test cases. Background technique [0002] At present, when performing software system testing, the function points to be tested are generally tested one by one through pre-set test cases. A test case is a set of inputs, execution conditions, and predicted results compiled for a particular purpose in order to test a program path or verify that a particular requirement is met. Test cases are mainly applicable to integration tests, system tests and regression tests. When implementing tests, testers take the set test cases as the standard and perform corresponding test operations in strict accordance with the test items and test steps set in the test cases. Situations are recorded in the test case management software to automatically generate test results documentation. When the scale of the test case expands to a certain extent, if all the items in the tes...

[0004] Using the above test method, although the test efficiency and test progress have been improved to a certain extent, it has brought the following technical defects: when selecting the test factor combination for generating test cases, the typical combination is only determined according to the priority of the test factors , the basis for determining the typical combination is relatively single. On the one hand, the test scenarios contained in the generated test cases may not accurately reflect the actual test requirements, which may cause the test cases to fail to cover the current test scenarios that most need to be tested. , and then lead to more serious fault leakage; on the other hand, the generated test cases are not well adapted to the actual test environment, such as the test cycle does not match the actual task cycle, and the coverage scale of the test scenario does not conform to the actual coverage scale, or the test case is not suitable for the current testing phase

[0005] In summary, using the existing method of generating test cases, there is a problem that the test scenarios contained in the test cases do not match the actual environment, resulting in low coverage of core test scenarios and poor efficiency of fault leakage control.
