### Question:
FileUtils { public static int getHashcodeFromFileContent(String filepath) { int hashcode; try { String fileContents = readFile(filepath); hashcode = Math.abs(fileContents.hashCode()); } catch (IOException e) { hashcode = 0; } return hashcode; }  static int countLines(File filename); static String readLineAt(int pos, File filename); static int getHashcodeFromFileContent(String filepath); static String readFile(String path);  }### Answer:
@Test public void getHashTest(){ assertTrue(FileUtils.getHashcodeFromFileContent("src/test/resources/fileUtils.txt")>0); }
