Documentation This task resource represents the "Rollback operation" operation. The client can use this resource to initiate rolling back a VNF lifecycle operation
Suite setup Check resource existance
*** Test Cases ***
Post Rollback operation task
[Documentation] The POST method initiates rolling back a VNF lifecycle operation if that operation has experienced a temporary failure,
... i.e. the related “VNF LCM operation occurrence” resource is in “FAILED_TEMP” state.
Depends on test Check resource FAILED_TEMP
Log Rollback a VNF lifecycle operation if that operation has experienced a temporary failure
Run Keyword If ${AUTH_USAGE} == 1 Set Headers {"Authorization":"${AUTHORIZATION}"}
Log Execute Query and validate response
Post ${apiRoot}/${apiName}/${apiVersion}/vnf_lcm_op_occs/${vnfLcmOpOccId}/rollback
Log Validate Status code
Integer response status 202
${headers}= Output response headers
Should Contain ${headers} Location
Log Validation OK
Post Rollback operation task Conflict (Not-FAILED_TEMP)
# TODO: Need to set the pre-condition of the test. VNF instance shall be in INSTANTIATED state
[Documentation] Conflict.
... The operation cannot be executed currently, due to a conflict with the state of the VNF instance resource.
... Typically, this is due to the fact that the VNF instance resource is not in FAILED_TEMP state,
... or another error handling action is starting, such as retry or fail.
... The response body shall contain a ProblemDetails structure, in which the “detail” attribute should convey more information about the error.
Depends on test failure Check resource FAILED_TEMP

[Teardown] #We cannot know if the "scale" operation is finished easily because the 202 indicates only whether the operation has been accepted, not whether the operation has been finished
Post Rollback operation task Not Found
# TODO: Need to create a vnfInstance which's instantiatedVnfInfo.scaleStatus is absent
[Documentation] Not Found
... Error: The API producer did not find a current representation for the target resource or is not willing to disclose that one exists.
... Specifically in case of this task resource, the response code 404 shall also be returned
... if the task is not supported for the VNF LCM operation occurrence represented by the parent resource,
... which means that the task resource consequently does not exist.
... In this case, the response body shall be present, and shall contain a ProblemDetails structure, in which the “detail” attribute shall convey more information about the error.
