For testing Not null or Undefined , you can write like this.

describe("Your Test Controller",() => {
    it("check for not null or undefined", function (){
        expect(Function(params)).not.toBeNull();
        expect(Function(params)).not.toBeUndefined();
    });
   } 

and if you want to test for being null and undefined

describe("Your Test Controller",() => {
        it("check for null or undefined", function (){
            expect(Function(params)).toBeNull();
            expect(Function(params)).toBeUndefined();
        });
       }
