Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the configuration and operation of the present invention. 1 schematically illustrates a system configuration for automatic extraction of hyperlink information and automatic website testing using the information according to an embodiment of the present invention.

As shown in Figure 1, the system configuration according to the present invention is connected to the test computer 100, the test computer 100 and a dedicated cable (for example, serial cable, parallel cable, USB, etc.) A device (e.g., an Internet phone, etc.) equipped with a browser providing an Internet access function, a local server connected to the test computer 100 and the Internet phone 110 through the Internet, which is a computer communication network. server; 120). Here, the test computer 100 and the Internet phone 110 may access various web servers 130 on the Internet through the Internet.

The operation method of the present invention in the system configuration of FIG. 1 will be described with reference to FIG. 2 is a flowchart illustrating an automatic extraction of hyperlink information and an automatic website testing method using the information according to an embodiment of the present invention. This is largely divided into two parts, an automatic hyperlink extraction part (step 200) and an automatic website testing part (step 220, step 240).

The automatic hyperlink extraction part (step 200) is a part performed in the test computer 100 of FIG. First, the web site to be tested and the depth of test are input, the web document is read from the web site to be tested, parsed, and the hyperlink information is extracted. By repeating the above process for the extracted hyperlinks, hierarchically extracting hyperlink (also referred to as anchor) information that can be accessed through the computer communication network within the test depth from the website under test, This is calculated as a separate file (hereinafter referred to as link information file). Here, a filtering process for removing duplicate information is performed together.

The website automatic test part (step 220, step 240) is a part performed for the browser test in the device 110 equipped with the browser shown in FIG. After the browser-equipped device 110 loads the link information file, the browser 110 sequentially accesses each hyperlink recorded in the link information file through the browser (reading a web document), and connects to each website (normal operation, Test for no connection, various errors, etc.).

The actual website connection status check is performed in the test computer 100, and for this purpose, an output message transmitted from each website is transmitted to the test computer 100 through a dedicated cable (step 220). The test computer 100 may detect an error phrase in the output message, display the output message through the virtual terminal, and store the output message in a file.

Here, the link information file (duplicate information is removed) that is the result of step 220 is transmitted / stored to the local server 120, so that the link information file can be loaded and referred to through the computer communication network in the device 110 equipped with a browser. do.

In addition, as the test depth increases, the hyperlink information tends to increase exponentially, so that the link information file is divided into a predetermined size in consideration of the limited resources of the device 110 on which the browser is mounted. 120, and the browser-mounted device may load and refer to each of the divided link information files sequentially.

3A and 3B, the detailed process of the hyperlink automatic extraction part (step 200) in step 200 will be described. 3A and 3B are detailed flowcharts of an automatic extraction method of hyperlink information according to an embodiment of the present invention.

First, the link extracter program is driven in the test computer 100 (step 300).

Next, the website under test can be entered in two ways. One is a list selection method and the other is a URL (Universal Resource Locator) direct input method. In the case of the list selection method, a list file (hereinafter referred to as a list file for extraction) that records a plurality of test website websites classified by each country or category is used. The user opens the directory where the list files for extraction are located and selects the file (step 312). When the list file for extraction is selected, the list file is loaded and a list of websites recorded in the file is displayed on the screen. The user selects a website with a mouse, among which the user wants to work (step 314). Of course, a plurality of websites may be selected, or an entire website displayed on the screen may be selected. The direct URL input method means a user directly inputs a URL of a test target website individually.

Next, a test depth is specified (step 318). The test depth is defined as "depth 0" for the initial test target website for convenience, and hyperlinks extracted (linked) from the initial test target website are defined hierarchically as "depth 1". In addition, an output file name for recording the extracted hyperlink information may be designated.

In FIG. 3A, for convenience, the input process of the test target website and the designation of the test depth are sequentially shown, but those skilled in the art may understand that their order may be changed. There will be.

After the test target website and the test depth are specified, when an execution command is input (step 330), the hyperlink information is repeatedly extracted from each test target website hierarchically up to the designated test depth (step 340).

Here, the extraction process is output on the screen, the content of the website is divided into "head" and "body" is output, and the hyperlink information extracted from the web document is also displayed in a separate output window It is preferable. In addition, the extracted hyperlink information is separately recorded in the output file (or the default file) designated in step 318. Of course, errors such as website inaccessibility are also recorded in a separate error file.

Assuming that a plurality of test target websites are input in a list selection method in step 340, the hyperlink extraction process will be described in detail with reference to FIG. 3B.

First, if all the test target websites are not completed, one test target website is selected (step 342), and the URL of the website is recorded in the output file (step 344).

Next, it is judged whether or not it is completed up to the designated test depth (step 346), and when it is completed, it proceeds to the next test target website.

If not, it is determined whether all websites at the current test depth have been completed (step 348), if so, the depth is increased (step 349) and then proceeds to the next depth. Otherwise, steps 350 through 358 are repeated sequentially for each website within the current test depth.

First, each website is accessed (step 350). That is, it reads a Hyper Text Markup Language (HTML) document. Next, hyperlink information is extracted from the web document (step 352). If login information is requested from the website, the login process is selectively performed in consideration of the test depth. In other words, if the website is the same as the designated test depth, no further login process will be necessary since it will no longer proceed to the lower level.

Next, duplicate information is removed in one web document (step 354). In operation 356, the controller 110 checks and removes duplicates of extracted information of the same or higher depth extracted hierarchically from the current test target website (step 356). Next, the hyperlink information from which duplicate information is removed is recorded in the output file (step 358).

Next, if testing of all websites at the current depth has not been completed, repeat steps 350 to 358 for other websites of the same depth (step 348). When all websites of the same depth are complete, increase the depth (step 349) to see the next depth. That is, it is checked whether the test is completed up to the designated depth (step 346), and if it is not completed up to the designated depth, the steps 348 to 358 are repeated for the new depth. If it is done up to the specified depth, then check the next test target website (step 342). In other words, if all the test target websites are not completed, steps 344 to 358 are repeated for the new test target website.

Finally, when all extraction processes are completed, duplicate information is removed from the output file (step 360). Then, for use in the website test part according to the embodiment of the present invention, the test device 110 transmits / stores the output file to the server accessible through the computer communication network (step 370). As described above, the output file is preferably divided into a predetermined size.

Subsequently, with reference to FIG. 4, the detailed process of the website automatic test part in step 220 is demonstrated. 4 is a detailed flowchart of a method for automatically testing a website (step 220 in FIG. 2) using hyperlink information according to an exemplary embodiment of the present invention.

First, in the browser-equipped device 110, a test start command is input, for example, in a hot key manner (step 400).

When a test start command is input, the browser-equipped device 110 loads a list file (hereinafter referred to as a test list file for testing) of a test target hyperlink information from a server through a computer communication network (step 410). In this case, the test list file is preferably divided into a predetermined size in consideration of the limited resources of the device 110 on which the browser is mounted.

Next, when the test list file is analyzed and each hyperlink information is sequentially transmitted to the browser (step 420), the browser is operated to access the website and read the web document (step 430).

Then, the content of the web document is output on the screen of the device equipped with a browser, and transmitted to the test computer 100 through a dedicated cable (step 440), and the test computer 100 analyzes the output message ( filtering), and check the website connection status (step 240).

Subsequently, it is checked whether all of the hyperlinks in the test list file have been tested (step 450). That is, if all hyperlink tests in the list file have not been completed, steps 420 through 440 are repeated for the next hyperlink.

When testing of all hyperlinks in the test listing file is completed, the server checks whether there is an additional test listing file (step 460). That is, if the additional list file exists, steps 410 to 450 are repeated for the next test list file.
