Testing

Integration Testing

It is proposed all systems should be compatible with NHS England - Personal Demographics Service - FHIR API and use the same test patients.

This can be found in PDS FHIR API test data packs

FHIR Validation

For details see FHIR Validation

Command Line Validation

See Using the FHIR Validator

The FHIR Validator works best with individual FHIR Resources and this may be an easier why to start checking your FHIR is correct. Due to API security requirements of the NHS England Ontology Service, this can not be used as a Terminology Server (the -tx parameter). This ig is configured to use the UK edition of SNOMED (83821000000107).

To use this Implementation Guide with the HL7 Validator, you will need to download this as a package (download link package.tgz) and then specify this NPM package file via the -ig package.tgz parameter.

The FHIR Validator defaults to validating individual FHIR resources (not FHIR Bundles), to validate FHIR resources in a Bundle see Validating a single resource in a bundle on the Using the FHIR Validator link above.

Examples to Validate a Bundle

laboratory-order O21 Validation Example

 java -jar validator_cli.jar c:\temp\bundle.json -version 4.0.1 -ig package.tgz -bundle ServiceRequest:0 https://hl7.mft.nhs.uk/StructureDefinition/ServiceRequest

unsolicited-observation R01 Validation Example

 java -jar validator_cli.jar c:\temp\bundle.json -version 4.0.1 -ig package.tgz -bundle DiagnosticReport:0 https://hl7.mft.nhs.uk/StructureDefinition/DiagnosticReport

Asking a FHIR Server

validator.fhir.org provides a web-based interface to the Validator CLI jar. This defaults to international FHIR and the options tab can be used to specify specific packages and SNOMED editions (this is listed as UK - 999000041000000102). This IG is not currently published to the registry and so ukcore should be used instead using the latest release
