@Test public void testBulkImportUtilStorageDetails() throws IOException, FHIRException { FHIRRequestContext.set(new FHIRRequestContext("default")); assertNotNull(BulkDataImportUtil.retrieveStorageDetails(loadTestFile("/testdata/import/import-demo.json"))); assertEquals( BulkDataImportUtil.retrieveStorageDetails(loadTestFile("/testdata/import/import-demo.json")).getType(), "https"); }
