    env.addObjectToLocation(new Wall(), northLoc);
    // object
    Assert.assertTrue(env.isBlocked(northLoc));
    // wall to the south of
    env.addObjectToLocation(new Wall(), southLoc);
    // object
    // wall to the west of
    env.addObjectToLocation(new Wall(), westLoc);
    // object
    Assert.assertEquals(4, env.getEnvironmentObjects().size());
    // should not move
    env.moveObject(a, XYLocation.Direction.North);
    // should not move
    env.moveObject(a, XYLocation.Direction.South);
    // should not move
    env.moveObject(a, XYLocation.Direction.West);
    // SHOULD move

    env.addObjectToLocation(c, new XYLocation(5, 7));
    env.addObjectToLocation(w1, new XYLocation(3, 10));
    // at this point agent A should be able to see B and C but not the wall
    // with a "vision radius" of 3
    Set<EnvironmentObject> visibleToA = env.getObjectsNear(a, 3);
    Assert.assertEquals(2, visibleToA.size());
    // agent B should be able to see A only
    Set<EnvironmentObject> visibleToB = env.getObjectsNear(b, 3);
    Assert.assertEquals(1, visibleToB.size());
    // move B South
    env.moveObject(b, XYLocation.Direction.South);
    // at this point both a and c should be visible to b
    visibleToB = env.getObjectsNear(b, 3);
    Assert.assertEquals(2, visibleToB.size());
    // move c near the wall
    env.moveObjectToAbsoluteLocation(c, new XYLocation(3, 11));
    // only the wall should be visible
