How to unit test conditional statements in jasmine

Can any one help me with testing conditional statement within a function in jasmine 

vm.onDisciplineCodeChange = function() {
                if ('other' === vm.selectedDisciplineCode) {
                    vm.selectedDiscipline.code = null;
                    vm.selectedDiscipline.userDefined = true;
                } else if('' === vm.selectedDisciplineCode) {
                    vm.selectedDiscipline = {
                        code: null,
                        userDefined: false,
                        userDefinedDiscipline: null
                    }
                } else {
                    vm.selectedDiscipline = {
                        code: vm.selectedDisciplineCode,
                        userDefined: false,
                        userDefinedDiscipline: null
                    }
                }
                vm.onDisciplineUpdated({discipline: vm.selectedDiscipline});
            };

I'm quite new to unit testing and following is the output i'm getting in generated report.

You see it because of it is not covered in unit testing Use following code to cover it in unit testing

it('if discipline is other', function() {
  // spy on
  spyOn(vm, 'onDisciplineUpdated');

  vm.selectedDisciplineCode = 'other';
  vm.onDisciplineCodeChange();
  expect(vm.selectedDiscipline.code).toBe(null);
  expect(vm.selectedDiscipline.userDefined).toBe(true);
  expect(vm.onDisciplineUpdated).toBeCalledWith({
    discipline: vm.selectedDiscipline
  });
})

it('if discipline is null', function() {
  vm.selectedDisciplineCode = '';
  vm.onDisciplineCodeChange();
  var result = {
    code: null,
    userDefined: false,
    userDefinedDiscipline: null
  };
  expect(vm.selectedDiscipline).toBe(result);
})


it('if discipline is different', function() {
  vm.selectedDisciplineCode = 'nothing';
  vm.onDisciplineCodeChange();
  var result = {
    code: vm.selectedDisciplineCode,
    userDefined: false,
    userDefinedDiscipline: null
  };
  expect(vm.selectedDiscipline).toBe(result);
})
