Abstract

Technologies are described herein for generating a suite of web tests that are then combined into a load test. A log file is received. The log file may contain one or more requests received at a web server. Relevant information is extracted from the log file into a data file. A web test template is retrieved. The web test template is populated with the relevant information from the data file to generate the web test.

Claims

1. A computer-implemented method for generating a web test, the method comprising computer-implemented instructions for:

receiving a log file containing one or more requests received at a web server;

extracting relevant information from the log file into a data file by

retrieving a line from the log file;

determining whether the line matches a match rule that identifies a type of request based on values of one or more attributes contained in each line;

in response to determining that the line matches the match rule, identifying a web test definition that registered the match rule, the web test definition identifying an extraction rule and the web test template;

retrieving a web test template;

determining whether the relevant information can be extracted from the line according to the extraction rule;

in response to determining that the relevant information can be extracted from the line according to the extraction rule, extracting the relevant information from the line according to the extraction rule; and

populating the web test template with the relevant information from the data file to generate the web test.

2. The computer-implemented method of claim 1, further comprising computer-implemented operations for:

in response to determining that the relevant information cannot be extracted from the line according to the extraction rule, retrieving heuristic data; and

utilizing the heuristic data to extract the relevant information from the line according to the extraction rule.

3. The computer-implemented method of claim 2, wherein the heuristic data comprises previous relevant information extracted from previous lines.

4. The computer-implemented method of claim 1, wherein the match rule comprises a first match rule name;

wherein the web test definition comprises a second match rule name; and

wherein identifying a web test definition that registered the match rule comprises identifying the web test definition having the second match rule name equal to the first match rule name.

5. The computer-implemented method of claim 1, wherein the web test template comprises a static component having one or more predefined values and a dynamic component having one or more empty variables;

and wherein populating the empty variables with the relevant information from the data file to generate the web test comprises populating the empty variables with the relevant information from the data file to generate the web test.

6. The computer-implemented method of claim 1, further comprising computer-implemented operations for combining the web test and other web tests to generate a load test.

7. The computer-implemented method of claim 6, wherein the load test comprises parameters for executing the web test and the other web tests.

8. The computer-implemented method of claim 7, wherein the parameters comprise counts or percentages in which the web test and the other web tests are executed or a number of users accessing the web server.

9. The computer-implemented method of claim 1, wherein extracting relevant information from the log file into a data file comprises extracting a uniform resource locator (URL), user information, or file information from the log file.

10. The computer-implemented method of claim 1, further comprising computer-implemented operations for normalizing the data file to condense a number of occurrences of similar data while maintaining ratios between different types of data.

11. A computer system, comprising:

a processor;

a memory communicatively coupled to the processor; and

a program module which (i) executes in the processor from the memory and (ii) which, when executed by the processor, causes the computer system to generate a web test by

receiving a log file comprising one or more lines, each of the lines corresponding to a request received at a web server,

retrieving a line from the log file,

identifying a match rule that identifies a type of request based on values of one or more attributes contained in each line that matches the line,

upon identifying a match rule that matches the line, identifying a web test definition that registered the match rule, the web test definition identifying an extraction rule and a web test template,

determining whether the relevant information can be extracted from the line according to the extraction rule,

in response to determining that the relevant information can be extracted from the line according to the extraction rule, extracting relevant information from the line according to the extraction rule into a data file by

determining whether the relevant information contains an ambiguity,

if the relevant information does not contain an ambiguity,

extracting the relevant information from the line according to the extraction rule,

if the relevant information does contain an ambiguity,

retrieving heuristic data, and,

utilizing the heuristic data to extract the relevant

information from the line according to the extraction rule,

retrieving the web test template, and

populating the web test template with the relevant information from the data file to generate the web test.

12. The computer system of claim 11, wherein the heuristic data comprises previous relevant information extracted from the previous lines;

wherein the match rule comprises a first match rule name;

wherein the web test definition comprises a second match rule name; and

wherein identifying a web test definition that registered the match rule comprises identifying the web test definition having the second match rule name equal to the first match rule name.

13. The computer system of claim 11, wherein the web test template comprises a static component having one or more predefined variables and a dynamic component having one or more empty variables;

and wherein populating the web test template with the relevant information to generate the web test comprises populating the empty variables with the relevant information to generate the web test.

14. The computer system of claim 11, further comprising computer-implemented operations for combining the web test and other web tests to generate a load test, the load test comprising parameters for executing the web test and the other web tests, the parameters comprising counts or percentages in which the web test and the other web tests are executed or a number of users accessing the web server.

15. The computer system of claim 11, wherein extracting relevant information from the log file into a data file comprises extracting a uniform resource locator (URL), user information, or file information from the log file.

16. The computer system of claim 11, further comprising computer-implemented operations for normalizing the data file to condense a number of occurrences of similar data while maintaining ratios between different types of data.

17. A computer-readable storage medium having computer-executable instructions stored thereon which, when executed by a computer, cause the computer to:

receive a log file comprising one or more lines, each of the lines corresponding to a request received at a web server;

retrieve a line from the log file;

identify a match rule that identifies a type of request based on values of one or more attributes contained in each line that matches the line;

upon identifying a match rule that matches the line, identify a web test definition that registered the match rule, the web test definition identifying an extraction rule and a web test template;

determine whether the relevant information can be extracted from the line according to the extraction rule by determining whether the relevant information contains an ambiguity;

in response to determining that the relevant information does not contain an ambiguity, extract the relevant information from the line according to the extraction rule into a data file;

in response to determining that the relevant information contains an ambiguity, retrieve heuristic data;

upon retrieving the heuristic data, utilize the heuristic data to extract the relevant information from the line according to the extraction rule;

retrieve the web test template; and

populate the web test template with the relevant information from the data file to generate a web test.
