Test td.function() after other td fuction()

[juniordesenv-zz]

My test:

    it('Retorna um Cliente', () => {
      const Clientes = {
        findOne: td.function(),
        populate: td.function()
      };


      td.when(Clientes.findOne({ _id: '58b431fd11b5272360652e45' }).populate('endereco.cidade')).thenResolve(modeloPadrao);

      const clientesController = new ClientesController(Clientes);
      return clientesController
                .getById({ params: { _id: '58b431fd11b5272360652e45' } })
                .then(response => expect(response.data).to.be.eql(modeloPadrao));
    });

My controller:

 getById(req) {
    return this.Clientes.findOne(req.params)
        .populate('endereco.cidade')
            .then(result => defaultResponse(result))
            .catch(error => errorResponse(error.message));
  }

Error: TypeError: Cannot read property 'populate' of undefined

You're trying to chain findOne and populate, but the Clientes object you've defined doesn't allow that.

You should:

const Clientes = td.object(['findOne', 'populate'])
td.when(Clientes.findOne({ _id: 'lol' })).thenReturn(Clientes)
td.when(Clientes.populate('endereco.cidade')).thenResolve(modeloPadrao)
