### Question:
OVFUtils { public static String getUrlImg(OvfDefinition ovfDocument, String fileId) { String urlImg = ""; File[] files = ovfDocument.getReferences().getFileArray(); if (files != null && files.length>0){ for (int j = 0; j < files.length; j++){ File file = files[j]; if (file.getId().equalsIgnoreCase(fileId)){ urlImg = file.getHref(); } } } else { logger.debug("No references section available in OVF!!"); } return urlImg; }  static String getApplicationName(String ovf); static String getDeploymentName(String ovf); static OvfDefinition getOvfDefinition(String ovf); static int getDiskCapacityInGb(int capacity, String units); static String getIsoPathFromVm(VirtualHardwareSection virtHwSection, OvfDefinition ovfDocument); static boolean usesACacheImage(VirtualSystem virtualSystem1); static boolean containsVMWithThatOvfId(String ovf, String ovfId); static VMLimits getUpperAndLowerVMlimits(VirtualSystem virtualSystem); static int getPriceSchema(ProductSection productSection); static ProductSection getProductionSectionForOvfID(String ovf, String ovfId); static VirtualSystem getVirtualSystemForOvfId(String ovf, String ovfId); static String getDiskId(VirtualHardwareSection virtualHardwareSection); static int getCapacity(OvfDefinition ovfDocument, String diskId); static String getFileId(String diskId, Disk[] diskList); static String getUrlImg(OvfDefinition ovfDocument, String fileId); static AsceticSLAInfo getVMSlaInfo(OvfDefinition ovfDocument, String slaInfoTerm, String ovfId); static AsceticSLAInfo getAppSlaInfo(OvfDefinition ovfDocument, String slaInfoTerm); static List<AsceticTermMeasurement> getVMTermMeasurement(OvfDefinition ovfDocument, String ovfId); static List<String> getOVFVMIds(OvfDefinition ovfDocument);  }### Answer:
@Test public void getUrlImgTest() { OvfDefinition ovfDocument = OVFUtils.getOvfDefinition(threeTierWebAppWithUpperLimitsString); String diskId = OVFUtils.getDiskId(ovfDocument.getVirtualSystemCollection().getVirtualSystemAtIndex(0).getVirtualHardwareSection()); String fileId = OVFUtils.getFileId(diskId, ovfDocument.getDiskSection().getDiskArray()); String url = OVFUtils.getUrlImg(ovfDocument, fileId); assertEquals("/DFS/ascetic/vm-images/threeTierWebApp/haproxy.img", url); }
