Functional Requirement

• User should be able to call an endpoint which returns the payload passed in the body.

Scope

• /echo
  • Only POST operation is allowed on the endpoint.
  • Request body should contain a valid JSON payload.
    • Invalid payload will return with 400 Bad Request
  • Response body will contain the same payload that was passed with 200 OK
  • Only application/json Content type is supported.
    • Any other Content type will return with 415 Unsupported Media Type
• /v2/echo?delay={IntegerValue}
  • Similar properties like /echo
  • ?delay={IntegerValue} if used, will delay the response for {IntegerValue} seconds
  • This helps in showing the behaviour of upstream Routing service in case of increased Latency.

How to run the server
