Abstract

A method that enables a tester to efficiently perform confirmation behavior of a Web page that utilizes DHTML or difference in behavior of the Web page among various browsers, or assignment of information relating to accessibility of the Web page or verification of the information. A method is provided that analyzes change in a Web page by determining states that can dynamically occur in response to an external event in a Web page that utilizes DHTML by analyzing at least one of DOM, style information for when rendered on a browser, input data from a user, and the value of a global variable in JAVA®SCRIPT, storing data that can identify each of the states, identifying state transition between the stored states, and reproducing the stored states.

Claims

1. A method for analyzing a change in a Web page that utilizes dynamic hypertext markup language, the method comprising:

determining an event that dynamically causes a transition in state in said Web page;

virtually executing said event in order to obtain a state after the transition;

obtaining the state in said Web page as data that is composed of at least one of a document object model, style information of elements rendered on a browser, data from a user input device, and a value of a global variable in JAVA®

SCRIPT;

determining whether the state is a state that has already appeared;

storing the state to form a stored state; and

reproducing the stored state in said Web page.

2. The method according to claim 1, further comprising:

collecting and analyzing hypertext transfer protocol requests that can occur from said Web page in virtually executing said event.

3. The method according to claim 2, further comprising:

obtaining and storing the state in a Web server as data that is composed of a value of a variable on said Web server that generates said Web page; and

reproducing the state in said Web server.

4. The method according to claim 1 further comprising:

presenting a state transition in said Web page to a user.

5. The method according to claim 3, further comprising:

presenting a transition of the state in said Web page and presenting the state in said Web server to a user.

6. The method according to claim 1, further comprising:

analyzing a state transition that has occurred in said Web page;

analyzing a structure of said Web page;

detecting an operation that causes a state transition in said Web page;

estimating a first role of elements that are affected by a phenomenon that occurs in response to the operation and a first state of elements that are affected by the phenomenon; and

estimating a second role of elements that are affected by the operation and a second state of elements that are affected by the operation.

7. The method according to claim 1, further comprising.

obtaining the state of said Web page on a plurality of browsers to obtain a plurality of states;

and

detecting a difference in the plurality of states among the plurality of browsers.

12. The method according to claim 2, further comprising:

presenting a state transition in said Web page to a user.

13. The method according claim 2, further comprising:

analyzing a state transition that has occurred in said Web page;

analyzing a structure of said Web page;

detecting an operation that causes a state transition in said Web page;

estimating a first role of elements that are affected by a phenomenon that occurs in response to the operation and a first state of elements that are affected by the phenomenon; and

estimating a second role of elements that are affected by the operation and a second state of elements that are affected by the operation.

14. The method according claim 3, further comprising:

analyzing a state transition that has occurred in said Web page;

analyzing a structure of said Web page;

detecting an operation that causes a state transition in said Web page;

estimating a first role of elements that are affected by a phenomenon that occurs in response to the operation and a first state of elements that are affected by the phenomenon; and

estimating a second role of elements that are affected by the operation and a second state of elements that are affected by the operation.

15. The method according claim 4, further comprising:

analyzing the state transition that has occurred in said Web page;

analyzing a structure of said Web page;

detecting an operation that causes the state transition in said Web page;

estimating a first role of elements that are affected by a phenomenon that occurs in response to the operation and a first state of elements that are affected by the phenomenon; and

estimating a second role of elements that are affected by the operation and a second state of elements that are affected by the operation.

16. The method according claim 5, further comprising:

analyzing a state transition that has occurred in said Web page;

analyzing a structure of said Web page;

detecting an operation that causes a state transition in said Web page;

estimating a first role of elements that are affected by a phenomenon that occurs in response to the operation and a first state of elements that are affected by the phenomenon; and

estimating a second role of elements that are affected by the operation and a second state of elements that are affected by the operation.

17. The method according to claim 2, further comprising:

obtaining the state of said Web page on a plurality of browsers to obtain a plurality of states; and

detecting a difference in the plurality of states among the plurality of browsers.

18. The method according to claim 3, further comprising:

obtaining the state of said Web page on a plurality of browsers to obtain a plurality of states; and

detecting a difference in the plurality of states among the plurality of browsers.

19. The method according to claim 4, further comprising:

obtaining the state of said Web page on a plurality of browsers to obtain a plurality of states; and

detecting a difference in the plurality of states among the plurality of browsers.

20. The method according to claim 6, further comprising:

obtaining the state of said Web page on a plurality of browsers to obtain a plurality of states; and

detecting a difference in the plurality of states among the plurality of browsers.

8. A client device for analyzing a change in a Web page that utilizes dynamic hypertext markup language, the client device comprising:

a state transition analysis unit for determining an event that dynamically causes a transition in state in said Web page;

an event execution unit for virtually executing said event in order to obtain a state after said transition;

a state storage unit for obtaining the state in said Web page as data that is composed at least one of a document object model, style information for when rendered on a browser, data from a user input device, and a value of a global variable in JAVA®

SCRIPT, the state storage unit also for determining whether the state is a state that has already appeared, and the state storage unit also for storing the state; and

a state reproducing unit for reproducing a stored state in said Web page.

9. A data processing system comprising a client device and a server device for analyzing change in a Web page that utilizes dynamic hypertext markup language, the data processing system further comprising:

a state transition analysis unit for determining an event that dynamically causes a transition in state in said Web page and in a Web server that generates said Web page;

an event execution unit for virtually executing said event in order to obtain a state after said transition;

a state storage unit for obtaining the state in said Web page and in the Web server as data that is composed at least one of a document object model, style information for when rendered on a browser, data from a user input device, a value of a global variable in JAVA®
