k6 test suite already includes test for single synchronous passthrough read operation:

GET http://localhost:8883/ncmp/v1/ch/${cmHandleId}/data/ds/${datastoreName}

This task is to add tests for the write operations POST, PUT, DELETE

See test case 6 in https://wiki.onap.org/display/DW/CPS-391Spike%3A+Define+and+Agree+NCMP+REST+Interface#CPS391Spike:DefineandAgreeNCMPRESTInterface-Characteristics-WIP

Presently, the DMI stub has a single delay for all data operations (DATA_FOR_CM_HANDLE_DELAY_MS). We need seperate DMI delays for read and write. The same DMI endpoint is used for all passthrough CRUD operations /v1/ch/{cmHandleId}/data/ds/{datastoreName}. To have different delays, we will need to check if the operation is read or write. The request body contains the information, for example:

{"operation":"read","cmHandleProperties":{"neType":"RadioNode"},"moduleSetTag":""}

So the read DMI delay will be used if operation is 'read', otherwise the write delay will be used.

A/C:

• A single plot showing requests per second for passthrough write operations (test case 6 in characteristics page)
• DMI is using the correct delay as in the characteristics page (670ms)
