java - Unit-testing method invocation (template method)? -

is possible unit-test method invocation on same class(in order , how many times invoked) ?

i.e. template method 1 below:

    abstract class foobarbaz {         public abstract void foo();        public abstract void bar();        public abstract void baz();         // want create unit test method, in following order        public mytemplatemethod() {           foo();  // want check foo first;           bar();  // want check bar second;           baz();  // want check baz third;        }     } 

edit - posted mockito code implementation

import junit.framework.testcase; import org.mockito.mockito;  public class foobarbaztest extends testcase {     public void testmytemplatemethodwithmockito() {       foobarbaz mocked = mockito.mock(foobarbaz.class);        mocked.mytemplatemethod();        mockito.verify(mocked, mockito.times(1)).foo();       mockito.verify(mocked, mockito.times(1)).bar();       mockito.verify(mocked, mockito.times(1)).baz();    } } 

edit - added stack trace

using mocking framework fine, if don't want rely upon external dependency, create test class implements abstract class. have abstract implementations of foo, bar, baz method add strings 'foo', 'bar', 'baz' shared list, in test method assert in list in correct order.

edit -- ive written tests both mockito , non-mock way. both pass--i hadn't used mockito before, might want try it....
