Motivation

The Problem

FHIR conformance testing is hard to do consistently:

• Tests live in separate repositories, not in the IG
• Each implementer writes their own tests — different tests, different gaps
• Tests lag IG updates by weeks or months
• No standard way to share or peer-review test suites

The root cause: tests are an afterthought, not a first-class IG artefact.

The Solution

FHIR Frog treats tests the same way FSH treats profiles — as source-controlled, peer-reviewed artefacts that ship with the IG.

Traditional approach	FHIR Frog approach
Tests separate from IG	Tests inside IG package
Custom test formats	Standard FHIR TestScript
Manual distribution	Published with IG automatically
No version control	Git history alongside profiles
Each org maintains own	Community uses same tests

Next Steps

• Tests in IGs — how tests ship with an IG
• TestScript Shorthand — concise authoring syntax
• FHIR Standards — TestScript, TestPlan and TestReport in FHIR
