AT:

• given:
  • Optimize and the engine are configured and up running
  • I defined a report and stored it in Optimize with,e.g., id "report1"
• when:
  • I evaluate the report with the given id, e.g. "report1" using the evaluate rest-api
  • Or I pass a complete new report definition and evaluate it using the evaluate rest-api
  • the report is configured with "view" as "raw data"
• then:
  • I get a list of process instance information containing:
    • process instance id
    • process definition id
    • process definition key
    • start date
    • end date
    • engine name process instance comes from
    • a list of variable instances used in the process instance

Hint:
The whole rest endpoint is already defined here:
