### Question:
VduBlueprint { public Map<String, byte[]> getAttachedFiles() { return attachedFiles; }  String getVduModelId(); void setVduModelId(String vduModelId); String getMainTemplateName(); void setMainTemplateName(String mainTemplateName); Map<String, byte[]> getTemplateFiles(); void setTemplateFiles(Map<String, byte[]> templateFiles); Map<String, byte[]> getAttachedFiles(); void setAttachedFiles(Map<String, byte[]> attachedFiles); @Override String toString();  }### Answer:
@Test public void testGetAttachedFiles() { byte[] attachedFileData = "some file data".getBytes(); attachedFiles = new HashMap<>(); attachedFiles.put("attachedKey1", attachedFileData); vduBlueprint.setAttachedFiles(attachedFiles); Assert.assertNotNull(vduBlueprint.getAttachedFiles()); Assert.assertTrue(vduBlueprint.getAttachedFiles().containsKey("attachedKey1")); Assert.assertTrue(vduBlueprint.getAttachedFiles().containsValue(attachedFileData)); }
