HL7 FHIR usage has expanded rapidly in recent years and has grown to become one of the dominant clinical data specifications in modern applications. Whether you are building a simple FHIR app or an enterprise scale FHIR solution, testing the FHIR related functionality is always complex. FHIR Proof's goal is to provide a set of utilities to aid in the efficient and accurate testing of application code that depends on other FHIR systems without the complexity or unreliability of third party components.

The aim of FHIR Proofer is to allow for software developers working with HL7 FHIR to test their application code without the need for onerous amounts of work to facilitate connecting to a FHIR server. This utility is meant to provide a lightweight and transient FHIR server for testing, POCs, or any other use.
