### Question:
VnfRollback { @Override public String toString() { return "VnfRollback: cloud=" + cloudSiteId + ", cloudOwner=" + cloudOwner + ", tenant=" + tenantId + ", vnf=" + vnfId + ", tenantCreated=" + tenantCreated + ", vnfCreated=" + vnfCreated + ", requestType = " + requestType + ", modelCustomizationUuid=" + this.modelCustomizationUuid + ", mode=" + mode; } VnfRollback();  VnfRollback(String vnfId, String tenantId, String cloudOwner, String cloudSiteId, boolean tenantCreated,
            boolean vnfCreated, MsoRequest msoRequest, String volumeGroupName, String volumeGroupId, String requestType,
            String modelCustomizationUuid);  VnfRollback(String vnfId, String tenantId, String cloudOwner, String cloudSiteId, boolean tenantCreated,
            boolean vnfCreated, MsoRequest msoRequest, String volumeGroupName, String volumeGroupId, String requestType,
            String modelCustomizationUuid, String orchestrationMode); String getVnfId(); void setVnfId(String vnfId); String getTenantId(); void setTenantId(String tenantId); String getCloudSiteId(); void setCloudSiteId(String cloudId); String getCloudOwner(); void setCloudOwner(String cloudOwner); boolean getTenantCreated(); void setTenantCreated(boolean tenantCreated); boolean getVnfCreated(); void setVnfCreated(boolean vnfCreated); MsoRequest getMsoRequest(); void setMsoRequest(MsoRequest msoRequest); String getVolumeGroupName(); void setVolumeGroupName(String volumeGroupName); String getVolumeGroupId(); void setVolumeGroupId(String volumeGroupId); String getRequestType(); void setRequestType(String requestType); String getVolumeGroupHeatStackId(); void setVolumeGroupHeatStackId(String volumeGroupHeatStackId); String getBaseGroupHeatStackId(); void setBaseGroupHeatStackId(String baseGroupHeatStackId); boolean isBase(); void setIsBase(boolean isBase); String getVfModuleStackId(); void setVfModuleStackId(String vfModuleStackId); String getModelCustomizationUuid(); void setModelCustomizationUuid(String modelCustomizationUuid); String getMode(); void setMode(String mode); @Override String toString();  }### Answer:
@Test public void toStringTest() { vnfRollback = new VnfRollback(vnfId, tenantId, cloudOwner, cloudSiteId, tenantCreated, vnfCreated, msoRequest, volumeGroupName, volumeGroupId, requestType, modelCustomizationUuid, orchestrationMode); assertEquals(VNF_ROLLBACK_STRING, vnfRollback.toString()); }
