If &quot;params&quot; element is specified, then &quot;targetId&quot; element is ignored.  For FHIR operations that require a resource (e.g. &quot;read&quot; and &quot;vread&quot; operations), the &quot;resource&quot; element must be specified when &quot;params&quot; element is specified.  If &quot;url&quot; and &quot;params&quot; elements are absent, then the request url will be constructed from &quot;targetId&quot; fixture if present.  For &quot;read&quot; operation, the resource and id values will be extracted from &quot;targetId&quot; fixture and used to construct the url.  For &quot;vread&quot; and &quot;history&quot; operations, the versionId value will also be used.   Test engines would append whatever is specified for &quot;params&quot; to the URL after the resource type without tampering with the string (beyond encoding the URL for HTTP).  The &quot;params&quot; element does not correspond exactly to &quot;search parameters&quot;.  Nor is it the &quot;path&quot;.  It corresponds to the part of the URL that comes after the [type] (when &quot;resource&quot; element is specified); e.g. It corresponds to &quot;/[id]/_history/[vid] {?_format=[mime-type]}&quot; in the following operation: GET [base]/[type]/[id]/_history/[vid] {?_format=[mime-type]}  Test engines do have to look for placeholders (${}) and replace the variable placeholders with the variable values at runtime before sending the request."/>
