Download the .zip and extract the easymock-3.1.jar
(http://easymock.org/Downloads.html)

Add the EasyMock jar file (easymock.jar) to your classpath
( Right click on Project Name -> Java Build Path -> Libraries (tab) -> Add External JARs (button) -> Browse )



import org.easymock.EasyMock;       //mock objects must have desired results explicitly coded

public class



        HttpServletRequest testRequest = EasyMock.createStrictMock( HttpServletRequest.class );     //strictmock forces correct method order calling
        HttpSession testSession = EasyMock.createStrictMock( HttpSession.class );
        String sessionId = EasyMock.createStrictMock( String.class );

        EasyMock.expect( testRequest.getSession( false ) ).andReturn( null );           //record expected behaviour, e.g. getsession(false) returns null
        EasyMock.expect( testRequest.getSession() ).andReturn( testSession );                   //record expected behaviour

//      EasyMock.expect( testSession.setMaxInactiveInterval( 60 ).andReturn( session ) );
//      EasyMock.expect( testSession.getId().andReturn( "1" ) );
//  session.setMaxInactiveInterval( minutes * 60 );

later on you can replay

        EasyMock.replay( testRequest );
//      EasyMock.replay( session );
