Using JUnit to test the private method of a Java class __java

In the Java project development process, it is sometimes necessary to test the private methods of the class, while private methods cannot be invoked directly, but the reflection mechanism can be used to invoke the following example:

  @Test public
  void Testgetelectiontimeout () throws Exception {
    int conftimeout = Conf1.getint (" Raft.election.timeout ");
    Method M = Node1.getclass (). Getdeclaredmethod ("Getelectiontimeout", new class[] {});
    M.setaccessible (true);
    
    for (int i = 0; i < i++) {Object result
      = M.invoke (Node1, null);
      
      int resultint = ((Integer) result). Intvalue ();
      SYSTEM.OUT.PRINTLN (result);
      Asserttrue (ResultInt >= conftimeout);
      Asserttrue (ResultInt <= conftimeout*2);
    }
