Abstract

A method of creating computing environment in a cloud computing environment for execution of a test is disclosed. The method includes loading a setup script from a script store. The loading is performed by a test manager that is in communication with the script store. The test manager checks if there are more setup scripts to be loaded. If yes, the remaining setup scripts are loaded by the test manager. The test manager then calculates computing resources needed to run all tests as coded in all loaded scripts. The test manager then attempts to reserve needed computing resources in a virtual data center using a data center infrastructure manager.

Claims

1. A method of creating computing environment for execution of a test, the method comprising:

(a) loading a setup script from a script store, the loading being performed by a test manager that is in communication with the script store;

(b) checking if there are more setup scripts to be loaded, if yes, performing step (a) again;

(c) calculating computing resources needed to run all tests as coded in all loaded scripts; and

(d) attempting to reserve the needed computing resources in a virtual data center through a virtual data center infrastructure manager.

2. The method as recited in claim 1, wherein the calculating includes determining computing resources to run all tests in parallel.

3. The method as recited in claim 2, wherein if a particular test in all tests is dependent on another test, the calculating includes determining computing resources to run all tests, except the particular test, in parallel.

4. The method as recited in claim 1, wherein if the attempt to reserve needed computing resources fails, the calculating includes reducing a number of tests to be run in parallel and performing step (d) again.

5. The method as recited in claim 4, wherein if not enough computing resources available to run tests as coded in any one of the setup scripts, notifying the test manager that no resources are available.

6. The method as recited in claim 4, wherein if resources are available to run a group of tests in parallel, then reserving computing resources in the virtual data center to run the group of tests in parallel, then dismantling the computing environment after recording results of the group of tests.

7. The method as recited in claim 4, wherein if resources are available to run a group of tests in parallel, then reserving computing resources in the virtual data center to run the group of tests in parallel, wherein if a test in the group of tests fails, then preserving the computing resources in same setup for a post test debugging.

8. The method as recited in claim 1, wherein the computing environment is isolated and accessible only for the execution of the test.

9. The method as recited in claim 1, wherein the loading includes identifying computing resource requirements to run the test as coded in the setup script.

10. The method as recited in claim 9, wherein if the computing resource requirements to run a test are identical to computing resource requirements to run another test in another setup script, merging the two setup scripts.

11. A computer readable media for storing programming instructions for creating computing environment for execution of a test, the computer readable media comprising:

programming instructions for loading a setup script from a script store, the loading being performed by a test manager that is in communication with the script store;

programming instructions for checking if there are more setup scripts to be loaded;

programming instructions for calculating computing resources needed to run all tests as coded in all loaded scripts; and

programming instructions for attempting to reserve needed computing resources in a virtual data center.

12. The computer readable media as recited in claim 11, further including programming instructions for notifying the test manager when no resources are available.

13. The computer readable media as recited in claim 11, wherein the programming instructions for loading includes programming instructions for identifying computing resource requirements to run the test as coded in the setup script.

14. The computer readable media as recited in claim 11, further including the programming instructions for merging a test script and another test script computing resource requirements to run a test in a setup script are identical to computing resource requirements to run another test in another setup script.

15. A test manager for creating computing environment for execution of a test, the test manager comprising:

a script loader to load one or more setup scripts from a testsuite store;

a testsuite merge module to merge two setup scripts;

an interfacing module to communicate with a virtual data center; and

a computing environment setup module to calculate computing resource requirements and reserving the computing resources in the virtual data center.

16. The test manager as recited in claim 15, further including a logging and reporting module to capture results of test executions.

17. The test manager as recited in claim 15, further comprising an execution module to coordinate test executions.
