### Question:
DefaultManagedArtifact implements ManagedArtifact { String getSubFolderName() { if (subFolderName == null) { String relPath = getAbsolutePath().replace(REPO_ABSOLUTE_PATH, ""); relPath = relPath.substring(relPath.indexOf(SystemUtils.FILE_SEPARATOR) + 1); String[] parts = relPath.split("[\\\\/]"); subFolderName = ((parts.length < 3) || (StringUtils.isBlank(parts[1]))) ? "" : parts[1]; } return subFolderName; } 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 testSubfolder() { DefaultManagedArtifact managedArtifact = new DefaultManagedArtifact(artifactFileOnePath); Assert.assertEquals(managedArtifact.getSubFolderName(), ""); }
