### Question:
ClasspathReader extends Reader { @SuppressWarnings("deprecation") @Override public final URL[] findResourcesByClasspath() { List<URL> list = new ArrayList<URL>(); String classpath = System.getProperty("java.class.path"); StringTokenizer tokenizer = new StringTokenizer(classpath, File.pathSeparator); while (tokenizer.hasMoreTokens()) { String path = tokenizer.nextToken(); File fp = new File(path); if (!fp.exists()) throw new ResourceReadingException("File in java.class.path does not exist: " + fp); try { list.add(fp.toURL()); } catch (MalformedURLException e) { throw new ResourceReadingException(e); } } return list.toArray(new URL[list.size()]); } ClasspathReader();  ClasspathReader(List<String> classesToScan); @Override final void read(); @SuppressWarnings("deprecation") @Override final URL[] findResourcesByClasspath(); @Override URL[] findResources(); final Filter getFilter(); final void setFilter(Filter filter); @Override InputStream[] findResourcesAsStream();  }### Answer:
@Test public void testFindResourcesByClasspath() { reader = new ClasspathReader(); URL[] urls = reader.findResourcesByClasspath(); Assert.assertNotNull(urls); Assert.assertTrue(urls.length > 0); }
