Testing a two-phase commit protocol conformance of a cloud based online transaction processing platform
Embodiments include methods, systems and computer program products for performing a two-phase commit conformance test for a cloud based online transaction processing system (OLTP). Aspects include receiving, by a test case manager of the OLTP from a transaction manager of the OLTP, a transaction event including metadata regarding a transaction and determining a state of the transaction. Aspects also include identifying a test case based on the metadata and the state of the transaction and issuing state events to the transaction manager, wherein the state events are determined based on the test case. Aspects further include obtaining log information from the transaction manager and determining compliance by the transaction manager with the two-phase commit conformance test based at least in part on the log information.
1. A method for performing a two-phase commit conformance test for a cloud based online transaction processing system (OLTP), the method comprising:
receiving, by a test case manager of the OLTP from a transaction manager of the OLTP, a transaction event including metadata regarding a transaction, wherein the transaction event is configured to initiate the two-phase commit conformance;
determining, by the test case manager, a state of the transaction;
identifying, by the test case manager, a test case based on the metadata and the state of the transaction;
issuing, by a test controller of the test case, state events to the transaction manager, wherein the state events are determined based on the test case;
obtaining, by a log analyzer of the test case manager, log information from the transaction manager; and
determining, by the test case manager, compliance by the transaction manager with the two-phase commit conformance test based on the log information,
wherein the transaction manager is configured to create the transaction events in a random manner that has a frequency that is configurable by a user.
2. The method of claim 1 , wherein the test case manager receives the transaction event from the transaction manager via a publish/subscribe server.
3. The method of claim 1 , wherein the metadata includes a type of a resource manager, a type of the transaction, a number of participants in the transaction and an identification of the participants.
4. The method of claim 1 , wherein the state events are transaction events that are configured to prompt a desired response by the transaction manager.
5. The method of claim 4 , wherein determining compliance by the transaction manager with the two-phase commit conformance test includes determining, based on the log information from the transaction manager, whether the transaction manager performed the desired response.
6. The method of claim 1 , wherein the state of the transaction is determining by accessing a state machine maintained by a test controller of the test case manager.
7. A computer program product, comprising:
a storage device; and
program code stored in the storage device, wherein the program code, when executed by a controller that controls a non-volatile memory array of a data storage system, causes the controller to:
receive, by a test case manager of the online transaction processing system (OLTP) from a transaction manager of the OLTP, a transaction event including metadata regarding a transaction, wherein the transaction event is configured to initiate the two-phase commit conformance;
determine, by the test case manager, a state of the transaction;
identify, by the test case manager, a test case based on the metadata and the state of the transaction;
issuing, by a test controller of the test case, state events to the transaction manager, wherein the state events are determined based on the test case;
obtain, by a log analyzer of the test case manager, log information from the transaction manager; and
determine, by the test case manager, compliance by the transaction manager with the two-phase commit conformance test based on the log information,
wherein the transaction manager is configured to create the transaction events in a random manner that has a frequency that is configurable by a user.
8. The computer program product of claim 7 , wherein the test case manager receives the transaction event from the transaction manager via a publish/subscribe server.
9. The computer program product of claim 7 , wherein the metadata includes a type of a resource manager, a type of the transaction, a number of participants in the transaction and an identification of the participants.
10. The computer program product of claim 7 , wherein the state events are transaction events that are configured to prompt a desired response by the transaction manager.
11. The computer program product of claim 10 , wherein determining compliance by the transaction manager with the two-phase commit conformance test includes determining, based on the log information from the transaction manager, whether the transaction manager performed the desired response.
12. The computer program product of claim 7 , wherein the state of the transaction is determining by accessing a state machine maintained by a test controller of the test case manager.
13. A system for testing a two-phase commit protocol conformance of a cloud based online transaction processing system (OLTP) platform, the system comprising:
a controller configured to be coupled to a non-volatile memory array, wherein the controller is configured to:
receive, by a test case manager of the OLTP from a transaction manager of the OLTP, a transaction event including metadata regarding a transaction, wherein the transaction event is configured to initiate the two-phase commit conformance;
determine, by the test case manager, a state of the transaction;
identify, by the test case manager, a test case based on the metadata and the state of the transaction;
issuing, by a test controller of the test case, state events to the transaction manager, wherein the state events are determined based on the test case;
obtain, by a log analyzer of the test case manager, log information from the transaction manager; and
determine, by the test case manager, compliance by the transaction manager with the two-phase commit conformance test based on the log information,
wherein the transaction manager is configured to create the transaction events in a random manner that has a frequency that is configurable by a user.
14. The system of claim 13 , wherein the test case manager receives the transaction event from the transaction manager via a publish/subscribe server.
15. The system of claim 13 , wherein the metadata includes a type of a resource manager, a type of the transaction, a number of participants in the transaction and an identification of the participants.
16. The system of claim 13 , wherein the state events are transaction events that are configured to prompt a desired response by the transaction manager.
17. The system of claim 16 , wherein determining compliance by the transaction manager with the two-phase commit conformance test includes determining, based on the log information from the transaction manager, whether the transaction manager performed the desired response.
18. The method of claim 1 , wherein determining compliance by the transaction manager with the two-phase commit conformance test includes determining, based on the log information from the transaction manager, whether the transaction manager performed the desired response.
