### Question:
DefaultManagedArtifact implements ManagedArtifact { String getUIDFolderName() { if (uidFolderName == null) { String relPath = getAbsolutePath().replace(REPO_ABSOLUTE_PATH, ""); relPath = relPath.substring(relPath.indexOf(SystemUtils.FILE_SEPARATOR) + 1); String[] parts = relPath.split("[\\\\/]"); uidFolderName = StringUtils.isEmpty(parts[0]) ? "" : parts[0]; } return uidFolderName; } DefaultManagedArtifact();   DefaultManagedArtifact(String pathName); @SuppressWarnings("unchecked") T getRequestParameters(); void initFromPath(String absolutePath); void initFromUploadedArtifact(UploadedArtifact uploaded); String getArtifactName(); byte[] getArtifactContents(); boolean matchesPathInfo(String pathInfo); boolean isExpired(); String getHttpContentType(); @Override boolean equals(Object other); @Override int hashCode(); @Override String toString(); String getAbsolutePath();  }### Answer:
@Test public void testUID() { DefaultManagedArtifact managedArtifact = new DefaultManagedArtifact(artifactFileOnePath); Assert.assertEquals(managedArtifact.getUIDFolderName(), "userOne"); }
