        [_outputFormat](http://hl7.org/fhir/uv/bulkdata/STU2/export.html#query-parameters):
        The format for the requested Bulk Data files to be
        generated as per FHIR Asynchronous Request Pattern. Defaults to
        application/fhir+ndjson. The server SHALL support Newline Delimited
        JSON, but MAY choose to support additional output formats. The server
        SHALL accept the full content type of application/fhir+ndjson as well
        as the abbreviated representations application/ndjson and ndjson.

      title 'Bulk Data Server supports "_since" query parameter'
      description <<~DESCRIPTION
        This test verifies that the server accepts an export request with the
        `[_since](http://hl7.org/fhir/uv/bulkdata/STU2/export.html#query-parameters)`
        query parameter.  It initiates a new export using a _since parameter of
        one week ago, and ensures that the export was initiated succesfully.

        The test does not attempt to verify that resources returned were
        modified after the _since date that was requested, because the Bulk Data
        specification provides latitude in determining exactly what data is
        returned by the server.  The purpose of this test is to ensure that
        export requests with this parameter are accepted and to highlight that
        support of this parameter is required.

        After the export was successfully initiated, it is then cancelled.
