Performance tests - concurrent requests response time (Test80)

[nir-r]

Background

Article 3.5 in "Technical Guidelines and Requirements ‎Document for FHIR Infrastructure ‎Implementation"
https://www.fhir-il-community.org/%D7%A1%D7%A8%D7%98%D7%99%D7%A4%D7%99%D7%A7%D7%A6%D7%99%D7%94

‎3.5. Performance and availability requirements
Organizational FHIR platform SHALL maintain a minimum annual uptime of 99.95%.‎
Organizational FHIR platform SHALL meet the following performance targets for 100 ‎concurrent FHIR REST API requests:‎
‎-‎ ‎95th percentile of FHIR REST API responses SHALL be returned within 200 milliseconds.‎
‎-‎ ‎99th percentile of FHIR REST API responses SHALL be returned within 2000 ‎milliseconds.‎
Note that these requirements only define the criteria for the FHIR platform's uptime, response ‎times, and concurrency. Data latency requirements (i.e. - time between data updates in the ‎source system and their availability via FHIR REST API) are defined in the [B.3] Information ‎Requirements document.‎

Requirment

• Integrate performance testing capabilities into FUME - use loadtest
• Test loadtest client's ability to output the desired amount of requests - Expose an API in FUME to mimic a server that returns 200 OK on each response
