The following describes specific embodiments to illustrate the implementation of the present invention, but it is not intended to limit the scope of the present invention.

Please refer to FIG. 1, which is a test case generation system according to an embodiment of the present invention. The aforementioned test case generation system 1 generates a test case 23 based on the test keyword 20. The aforementioned system includes a conversion module 11, a generation module 12, and an orchestration module 13 connected to each other. After the conversion module 11 obtains at least one keyword 20, it analyzes the test keyword 20 to provide a corresponding plurality of test steps. The generating module 12 then associates the test steps as the steps in FIG. 22 with the nodes. The orchestration module 13 then forms a software test case 23 according to the test step attributes of the nodes. The aforementioned conversion module 11, generation module 12, and orchestration module 13 can be implemented using software modules. The aforementioned test case is defined as the process of the software operation page.

The aforementioned test steps are "include test steps" or "exclude test steps". Accordingly, each node is marked as including the step attribute or excluding the step attribute. The execution path of the software test case 23 has only the nodes marked as "include step attributes"; in other words, the execution path of the aforementioned software test case 23 excludes the nodes marked as "exclude step attributes". To further explain, the steps of “including test steps” and “excluding test steps” mentioned before refer to the steps of software testing, not the steps of the method in this case.

Please refer to FIG. 2, which is a test case generated according to another embodiment of the present invention. method. The method is applied to a computer device, and a test case is generated according to a test keyword. The method mainly includes the following steps:

S101: Analyze the test keywords to provide a corresponding plurality of test steps.

S102: Use the test steps as the nodes of the step association graph.

S103: Form a software test case according to the test step attributes of the node.

In another embodiment of the present invention, a computer program product for generating a test case is provided. When a computer device loads and executes the computer program product, the steps described in the foregoing method can be completed.

This case is explained by telecommunication service software testing, but the software tested is not limited. Please refer to FIG. 3, which is a schematic flowchart of the system of the foregoing embodiment. Compared with the conventional technology, it is impossible to set appropriate test content. This case allows the tester to set the software page range to be tested, the function to be tested, and the focus of the inspection through the keyword 20. After the conversion module 11 obtains the keywords 20, it will query the test steps (as shown in Table 1) corresponding to each keyword 20 from the database, and aggregate the test steps into a step set 21.

The aforementioned "including test steps" are {A1, A2}, {B1, B2, A2}, {B4}; and the exclusion test steps are {null}, {B3}, {null}. Then, for each keyword 20, the "include test step" and "exclude test step" are respectively output from the union set, and the test step set 21 {A1, A2, B1, B2, B4} is included, and the test step is excluded Collection 21 {B3}

Next, the generating module 12 accesses the predefined step relationship table as shown in Table 2. The left column of the table is the step code, the middle column is the step that the step can be connected to in the system under test, and the right column is the step that can be read. description. Then, according to the step code and the steps that can be connected, the step correlation diagram 22 shown in FIG. 4 is generated.

After completing the step correlation diagram 22, the orchestration module 13 marks the inside of the step correlation diagram 22 according to "Include test step set 21" {A1, A2, B1, B2, B4} and "Exclude test step set 21" {B3} Node. Then, the orchestration module 13 removes the node marked as "excluded" (ie, node B3), and finds the execution path in the graph. Its execution path can be achieved using an approximate algorithm for the traveling salesman problem. The virtual code table of the algorithm is shown in Table 3:

Through the aforementioned algorithm, the following execution path can be generated: case start → C1 → A1 → A2 → C1 → B1 → B4 → B2 → C1 → C2 → case end

In addition, the system can also query the description of the steps in Table 2 and output the test case 23 description file described in Table 4:

After obtaining the execution path of the software test case 23, the system can load and execute the execution path through software (for example, selenium) used for automatic testing to execute the software test of the target software.

The aforementioned software modules can be implemented by programming languages such as ASP, C / C ++ / C #, Java, Python, PHP, Perl, but the types of programming languages are not limited to this.

The above detailed description is a specific description of a feasible embodiment of the present invention, but this embodiment is not intended to limit the patent scope of the present invention. Any equivalent implementation or change that does not depart from the technical spirit of the present invention should be included in Within the scope of the patent in this case.
