Abstract

Test results can be analyzed and linked using an automated system. In a first embodiment, an error log can be received including log data associated with an error. The log data can be parsed to transform it into a standardized format to allow for easier searching and comparison. Once standardized, an automatic comparison can be made between the parsed log data and previous errors obtained from error logs. If a match is found between the parsed log data and a previous error, then the parsed log data can be linked to the previous error so as to generate a relationship between the two.

Claims

1. A method of analyzing an error log, comprising:

receiving an error log including log data associated with an error;

parsing the log data to transform the log data into a standardized format;

automatically comparing the parsed log data to one or more previous errors obtained from error logs; and

if a match is found between the parsed log data and the one or more previous errors, then linking the parsed log data to at least one of the matched, previous errors.

2. The method of claim 1, further including receiving user input to change the linking of the parsed log data.

3. The method of claim 1, wherein automatically comparing includes comparing an error type in the log data to an error type in a candidate error amongst the one or more previous errors, and if the error types match, comparing an error message associated with the log data to an error message in the candidate error.

4. The method of claim 3, further including comparing a trace of the log data with a trace of the candidate error, wherein the trace includes a plurality of instructions executed before an error occurred.

5. The method of claim 4, further including comparing a location in a source code associated with the log data where the error occurred with a location of the source code associated with the candidate error.

6. The method of claim 1, wherein the error log is generated by a script that is testing user interface buttons in an application or non-user-interface functionality of the application.

7. The method of claim 1, wherein receiving the error log is through an application programming interface.

8. The method of claim 1, wherein parsing the log data includes receiving the error log in a first format and transforming the error log to a second format, different than the first format.

9. The method of claim 1, wherein automatically comparing the parsed log data to one or more of the previous errors includes searching through a database and generating a base linking type if no match is found.

10. The method of claim 9, wherein linking the parsed log data to at least one of the matched, previous errors, includes matching the parsed log data to a previously generated linking type.

11. One or more computer-readable storage medium for executing a method for analyzing an error log, the method comprising:

receiving an error log obtained as a result of automatically testing an application;

storing the error log in a library of log events;

comparing the error log to error logs previously received; and

if a match is found between the error log and a previously received error log, then linking the error log to the previously received error log that was matched.

12. The one or more computer-readable storage medium of claim 11, further including parsing the error log so as to convert it from a first format to a second format so that error logs stored in the library are consistently in the second format.

13. The one or more computer-readable storage medium of claim 11, wherein linking includes transforming a linking type to match a linking type of the previously received error log that was matched.

14. The one or more computer-readable storage medium of claim 11, wherein finding a match includes matching an error log type and an error message between the error log and the previously received error log.

15. The one or more computer-readable storage medium of claim 14, wherein finding a match further includes matching a code trace, leading up to the error, between the error log and the previously received error log.

16. The one or more computer-readable storage medium of claim 11, further including receiving user input to change the linking and modifying linking information in the library in response thereto.

17. The one or more computer-readable storage medium of claim 11, further including reading source code of the application to determine a first location in the source code associated with the error log and comparing the determined first location with a second location in the source code associated with the previously received error log.

18. A system for analyzing an error log, comprising:

a database library including stored previous errors that occurred;

a parser for receiving the error log including a current error and transforming the error log into a predetermined standard format for storage in the database library; and

a matcher for searching the database library and comparing information in the error log with the previous errors in order to determine if the previous errors are associated with the current error.

19. The system of claim 18, further including an updater coupled to the database library, the updater for changing linking information between the current error and the previous errors.

20. The system of claim 18, further including a result fetcher for receiving a user request to search for errors in the database library and for providing displayable results to a user interface.
