Abstract

Embodiments of the invention relate to maintaining a repository of subroutines used by a software program under test based on an analysis of subroutine usage logs. One aspect of the invention concerns a system for analyzing a log of subroutine usage by an application under test to identify subroutines used by the application based on actions in the subroutines, and comparing the identified subroutines against a repository of subroutines applicable to the application. The system may further designate a subroutine in the repository as a matching subroutine, modify or delete a subroutine, or add a new subroutine to the repository.

Claims

1. A system comprising:

a data storage component for storing a log of subroutine usage by an application under test;

a processor coupled to the data storage component and configured to;

analyze the log to identify subroutines used by the application based on actions in the subroutines, wherein the identifying subroutines comprises;

segment the log into sequences of related actions based on a time period;

map each sequence of related actions into a sequence of action classes;

analyze the resulting sequences of action classes to identify a common substring; and

output the common substring as one of the subroutines used by the application;

compare the identified subroutines against a repository of subroutines applicable to the application; and

designate a first subroutine in the repository as a matching subroutine wherein the first subroutine is used by the application.

2. The system of claim 1, wherein the proce3ssor is configured to delete a second subroutine in the repository wherein the second subroutine is not used by the application.

3. The system of claim 1, wherein the processor is configured to add a second subroutine to the repository wherein the second subroutine is used by the application but not in the repository.

4. The system of claim 1, wherein the processor is configured to identify a second subroutine in the repository for modification wherein the second subroutine partially matches one of the subroutines used by the application.

5. A computer program product comprising a non-transitory computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising:

computer readable program code configured to analyze a log of subroutine usage by an application under test to identify subroutines used by the application based on actions in the subroutines, wherein the identifying subroutines comprises;

segment the log into sequences of related actions based on a time period;

map each sequence of related actions into a sequence of action classes;

analyze the resulting sequences of action classes to identify a common substring; and

output the common substring as one of the subroutines used by the application;

computer readable program code configured to compare the identified subroutines against a repository of subroutines applicable to the application; and

computer readable program code configured to designate a first subroutine in the repository as a matching subroutine wherein the first subroutine is used by the application.

6. The computer program product of claim 5, wherein the subroutine repository is initialized with a user list of subroutines.

7. The computer program product of claim 5, wherein each of the subroutines is a sequence of action steps.

8. The computer program product of claim 5, wherein the application under test is a web application and the subroutine usage log is a web interaction log.

9. The computer program product of claim 8, wherein the web interaction log comprises at least one of web links, web page selections, and input text.

10. The computer program product of claim 8, wherein the computer readable program code comprises computer readable program code configured to segment the web interaction log by day.
