### Question:
GrpcConversionUtils { static X509Context toX509Context(final Iterator<Workload.X509SVIDResponse> x509SvidResponseIterator) throws X509ContextException { if (!x509SvidResponseIterator.hasNext()) { throw new X509ContextException("X.509 Context response from the Workload API is empty"); } val x509SvidResponse = x509SvidResponseIterator.next(); return toX509Context(x509SvidResponse); } private  GrpcConversionUtils();   }### Answer:
@Test void toX509Context_emptyResponse() { Iterator<Workload.X509SVIDResponse> iterator = Collections.emptyIterator(); try { GrpcConversionUtils.toX509Context(iterator); } catch (X509ContextException e) { assertEquals("X.509 Context response from the Workload API is empty", e.getMessage()); } }
