The CQL Testing Tool is a tool that allows you to test Clinical Quality Language (CQL) code against mock FHIR resources. It is designed to help you test your CQL code before using it in a production environment.
To use the CQL Testing Tool, you need to provide the CQL code and a FSH snippet with mock FHIR resources. Once you've entered the code, you can click the Execute CQL button to run the CQL against the compiled mock resources and see the results.
