Abstract

A system includes sending of requests to a computing system based on a first number of users associated with a load test, evaluation of one or more characteristics of the computing system while sending the requests, determination to modify the first number of users to a second number of users based on the one or more evaluated characteristics, and sending of requests to the computing system based on the second number of users.

Claims

1. A method implemented by a computing system in response to execution of program code by a processor of the computing system, the method comprising:

sending requests to a computing system based on a first number of users associated with a load test;

while continuing to send the requests, evaluating one or more characteristics of the computing system;

while continuing to send the requests, determining to modify the first number of users to a second number of users based on the one or more evaluated characteristics;

in response to the determination to modify the first number of users to the second number of users, sending requests to the computing system based on the second number of users, and

while continuing to send the requests, determining whether to abort and restart the load test based on a number of times users have been added to the load test.

2. A method according to claim 1, wherein the characteristic indicates a usage level of one or more system resources of the computing system.

3. A method according to claim 1, wherein sending requests to the computing system based on the first number of users associated with the load test comprises:

sending requests to the computing system based on the first number of users associated with the load test for a predetermined time period.

4. A method according to claim 1, wherein determining to modify the first number of users comprises:

determining whether a value of one or more of the evaluated characteristics has reached a threshold.

5. A method according to claim 4, further comprising:

while continuing to send the requests, determining that the threshold has been reached; and

in response to the determination that the threshold has been reached, continuing to send requests to the computing system based on the current number of users for a predetermined time period.

6. A method according to claim 5, further comprising:

adding a third number of users to the load test;

sending requests to the computing system based on a second current number of users associated with the load test for a second predetermined time period;

removing a fourth number of users from the load test; and

sending requests to the computing system based on a third current number of users associated with the load test for a third predetermined time period.

7. A non-transitory medium storing computer-executable program code, the program code executable by a computing device to:

send requests to a computing system based on a first number of users associated with a load test;

while continuing to send the requests, evaluate one or more characteristics of the computing system while sending the requests;

while continuing to send the requests, determine to modify the first number of users to a second number of users based on the one or more evaluated characteristics;

in response to the determination to modify the first number of users to the second number of users, send requests to the computing system based on the second number of users, and

while continuing to send the requests, determine whether to abort and restart the load test based on a number of times users have been added to the load test.

8. A medium according to claim 7, wherein the characteristic indicates a usage level of one or more system resources of the computing system.

9. A medium according to claim 7, wherein the sending of requests to the computing system based on the first number of users associated with the load test comprises:

sending of requests to the computing system based on the first number of users associated with the load test for a predetermined time period.

10. A medium according to claim 7, the program code to determine to modify the first number of users further executable by a computing device to:

while continuing to send the requests, determine whether a value of one or more of the evaluated characteristics has reached a threshold.

11. A medium according to claim 10, the program code further executable by a computing device to:

while continuing to send the requests, determine that the threshold has been reached; and

in response to the determination that the threshold has been reached, continue to send requests to the computing system based on the current number of users for a predetermined time period.

12. A medium according to claim 11, the program code further executable by a computing device to:

add a third number of users to the load test;

send requests to the computing system based on a second current number of users associated with the load test for a second predetermined time period;

remove a fourth number of users from the load test; and

send requests to the computing system based on a third current number of users associated with the load test for a third predetermined time period.

13. A system comprising:

a computing system comprising a first processor and a first memory; and

a testing system comprising a second processor and a second memory, the testing system to;

send requests to the computing system based on a first number of users associated with a load test;

while continuing to send the requests, evaluate one or more characteristics of the computing system while sending the requests;

while continuing to send the requests, determine to modify the first number of users to a second number of users based on the one or more evaluated characteristics;

in response to the determination to modify the first number of users to the second number of users, send requests to the computing system based on the second number of users, and

determine whether to abort and restart the load test based on a number of times users have been added to the load test.

14. A system according to claim 13, wherein the sending of requests to the computing system based on the first number of users associated with the load test comprises:

sending of requests to the computing system based on the first number of users associated with the load test for a predetermined time period.

15. A system according to claim 13, wherein the determination to modify the first number of users comprises:

determination of whether a value of one or more of the evaluated characteristics has reached a threshold.

16. A system according to claim 15, the testing system further to:

while continuing to send the requests, determine that the threshold has been reached; and

in response to the determination that the threshold has been reached, continue to send requests to the computing system based on the current number of users for a predetermined time period.

17. A system according to claim 16, the testing system further to:

add a third number of users to the load test;

send requests to the computing system based on a second current number of users associated with the load test for a second predetermined time period;

remove a fourth number of users from the load test; and

send requests to the computing system based on a third current number of users associated with the load test for a third predetermined time period.
