### Question:
UploadTerminologyCommand extends BaseCommand { @VisibleForTesting static void setTransferSizeLimitForUnitTest(long theTransferSizeLimit) { if (theTransferSizeLimit <= 0) { ourTransferSizeLimit = DEFAULT_TRANSFER_SIZE_LIMIT; }else { ourTransferSizeLimit = theTransferSizeLimit; } }  @Override String getCommandDescription(); @Override String getCommandName(); @Override Options getOptions(); @Override void run(CommandLine theCommandLine);  }### Answer:
@Test public void testSnapshotLargeFile() throws IOException { UploadTerminologyCommand.setTransferSizeLimitForUnitTest(10); writeConceptAndHierarchyFiles(); when(myTermLoaderSvc.loadCustom(any(), anyList(), any())).thenReturn(new UploadStatistics(100, new IdType("CodeSystem/101"))); App.main(new String[]{ UploadTerminologyCommand.UPLOAD_TERMINOLOGY, "-v", "r4", "-m", "SNAPSHOT", "-t", "http: "-u", "http: "-d", myConceptsFileName, "-d", myHierarchyFileName }); verify(myTermLoaderSvc, times(1)).loadCustom(any(), myDescriptorListCaptor.capture(), any()); List<ITermLoaderSvc.FileDescriptor> listOfDescriptors = myDescriptorListCaptor.getValue(); assertEquals(1, listOfDescriptors.size()); assertThat(listOfDescriptors.get(0).getFilename(), matchesPattern(".*\\.zip$")); assertThat(IOUtils.toByteArray(listOfDescriptors.get(0).getInputStream()).length, greaterThan(100)); }
