java - Android unit test for Enum type -

i came across strange. example of function:

public class f {   public enum pawn {black, white}    public pawn x;   public f(){       this.x = pawn.black;   }   public pawn test(){       return this.x;   } } 

unit test this:

import junit.framework.assert; import junit.framework.testcase;  import <package ... >.f;  public class ftest extends testcase {     public void testvalue(){         f mf = new f();         assert.assertsame(pawn.black, mf.test());     } } 

and junit output:

junit.framework.assertionfailederror: expected same:<black> not:<black>  expected :black actual   :black 

black not black , black. it's black magic. :/ can make work (i.e. pass test)?

you need assertequals, not assertsame

assertequals(java.lang.object expected, java.lang.object actual) asserts 2 objects equal.

assertsame(java.lang.object expected, java.lang.object actual) asserts 2 objects refer same object

your code comparing object f.x against enum object pawn.black. should be

public void testvalue(){     f mf = new f();     assert.assertequals(f.pawn.black, mf.test()); }
