Description

  The present invention relates to a system test apparatus that tests whether a desired result is obtained when a program specification for constructing a system is executed in a system such as a Web system.

  Conventionally, when testing an information system such as a Web system, it has been performed manually as follows. That is, first, a test specification including a screen definition and screen transition is created. Next, based on this test specification, a predetermined value is input from the Web browser, and the Web page returned from the server is visually confirmed. In the case of a retest, the same test data is input again.

  Alternatively, based on the test specification, start a tool that traces input, input a predetermined value from the Web browser, visually check the Web page returned from the server, and use the trace tool for retesting. In some cases, there was no need to input the same test data.

  On the other hand, there has conventionally been a system development method and a development support system aimed at reducing the burden of design development work and speeding up design development (for example, see Patent Document 1). In the development of a Web application system, each component of Servlet, JSP, and Bean is defined in a one-to-one relationship corresponding to each screen, and the correspondence of each component is clarified. It is.

As described above, conventionally, when testing a system, the input is manually performed based on the test specification, and the result is visually confirmed. However, for such a test, it is necessary to check various input patterns, screen transitions, error output, etc., and the creation of specifications and data input are very laborious, and it is a burden on the system designer. In addition, there is a problem that an input error or a check omission causes a deterioration in quality.
In addition, although there is a system that automates the system development support system as described above, a technique for automating the system test itself has not been realized.

Next, the operation of the first embodiment will be described.
FIG. 2 is a flowchart showing the operation of the system test apparatus 200 according to the first embodiment.
Moreover, each program example and a display screen are shown in FIGS. 3 shows a program example of the setting file 106. FIG. 4 shows an input data processing program specification 103, FIG. 5 shows a business logic execution program specification 104, FIGS. 6 and 7 show a screen generation program specification 105, 8 shows a test pattern 301, FIG. 9 shows a test specification 303, FIGS. 10 and 11 show a Web page 302, and FIG. 12 shows a display screen by the Web page 302 of FIGS.

  First, the execution request analysis unit 211 in the test pattern generation unit 210 analyzes the setting file 106 in the Web system 100 (step ST1). For example, if the setting file 106 includes a description as shown in FIG. 3, a character string “url =...” Is designated in advance as a request character string, and the execution request analysis unit 211 Based on this information, a request character string is identified, and an execution request is extracted from the corresponding part. The setting file 106 describes the correspondence between the input data processing program specification 103 as shown in FIG. 4 corresponding to the execution request and the business logic execution program specification 104 as shown in FIG.

  Next, the parameter analysis unit 212 analyzes the parameters described in the input data processing program specification 103 as shown in FIG. 4 of the Web system 100 (step ST2), and inputs corresponding to the execution request in the setting file 106 It is determined whether there is a parameter (step ST3). That is, it is given in advance that the part after “parameter” is a part indicating a parameter in the input data processing program specification 103, and the parameter analysis unit 212 identifies the parameter based on this information. In the input data processing program specification 103 of FIG. 4, since the description about the input parameter is included, the determination process in step ST3 proceeds to the next step ST4.

  In step ST4, the data range analysis unit 213 in the test pattern generation unit 210 analyzes the parameter range described in the input data processing program specification 103. That is, the data range analysis unit 213 identifies a part indicating a parameter range based on information specifying which part in the input data processing program specification 103 is a parameter type. For example, the input data processing program specification 103 shown in FIG. 4 includes a description indicating a parameter range such as [AZ] [0-9] or 1 <price <10000 as input data designation. Analyze these data ranges. Next, the test pattern output unit 214 outputs output data corresponding to the assumed input data from the execution request and its corresponding parameter and data range based on the analysis results of the execution request analysis unit 211 to the data range analysis unit 213. Is created (step ST5). Next, the test pattern output unit 214 combines the execution request with the corresponding parameter and output data, generates a test pattern and test data, and outputs this as the test pattern 301 (step ST6). For example, in the test pattern 301 shown in FIG. 8, a value such as “A0” is embedded as test data in the parameter range [AZ] [0-9] in the input data processing program specification 103.

  Next, the confirmation screen data generation unit 220 refers to the input data processing program specification 103 by the screen definition analysis unit 221, and the relationship between the screen generation program specification 105 and the test pattern 301 as shown in FIGS. 6 and 7. Is analyzed (step ST7). Then, output data generated by the input data (test data) in the test pattern is determined on the screen described in the screen generation program specification 105 (step ST8). Next, the data output unit 222 creates a Web page to be a test result confirmation screen in which the output data determined by the screen definition analysis unit 221 is embedded, and outputs this as a Web page 302 to the test specification generation unit 230 ( Step ST9). This Web page 302 has the description shown in FIGS. 10 and 11, for example, and the actual screen is as shown in FIG.

  The test specification generation unit 230 corresponds to the execution request and corresponding parameters and input data based on the test pattern 301 output from the test pattern generation unit 210 and the Web page 302 output from the confirmation screen data generation unit 220. A test specification combining the output data to be generated and the Web page 302 is created and output (step ST10). That is, the output test specification 303 includes input data and information indicating the result as shown in FIG.

  If there is no input parameter corresponding to the execution request in step ST3, a test pattern 301 having the execution request as a single pattern is output (step ST11). The confirmation screen data generation unit 220 determines whether there is output data defined by the test pattern 301 (step ST12). If it exists, the process proceeds to step ST9. The created Web page 302 is created, and the process proceeds to step ST10.

  Next, the automatic test execution unit 240 interprets the test specification 303 and performs the test (step ST13). That is, screen data is generated by applying the test pattern and test data in the test specification 303 to the screen generation program specification 105, and whether or not the screen data is consistent with the Web page 302 is determined. Determine (step ST14). If the test result is correct, the test result document 304 indicating acceptance is output (step ST15). If the test result is not correct, the test result document 304 indicating failure is output (step ST16).

However, the present invention is not limited to this, and a specific program specification is analyzed and an execution request, a parameter and a data range corresponding thereto are analyzed. Any other system can be applied as long as it can be extracted.
