Jasmine test doesn't create a new instance of a class

Question

I'm trying to apply a Jasmine test to my JS program (just a game) and it doesn't create new instances for some reason. Maybe some of you can help me find the error.

'use strict';


describe('logic(bingo)',function() {
    var bin
    beforeEach(function() {
        bin = new Bingo('Alex')
    })

    it('should throw error if name is not a string',function() {
        bin=new Bingo()
        expect(function() {
            return bin.name
        }).toThrowError('Input a string name')
    })

    it('should board.length===3 and board[0].length===5',function() {
        expect(bin.board.length).toBe(3)
        expect(bin.board[0].length).toBe(5)
    })
    }

bin doesn't store a "new Bingo". It keeps being undefined. This class Bingo is declared in a different file, the links are correct.

Thanks in advance.

Answer 1

how are you throwing an error when name is not supplied or is not a string?

i think it should be in constructor and something like:

...
if(!name || typeof name !== 'string') {
  throw new Error('Input a string name');
}
...

and also checking for it throws on instantiation not on getter:

    it('should throw error if name is not a string',function() {
      expect(function() {
        new Bingo(1)
      }).toThrowError('Input a string name')
    })
