lodash functions are not recognizing in angular6 and jasmine test cases

I am using lodash library in my angular application for trimming text box value.

The code am using like this This is working fine when i run the app. 

import _ from 'lodash';
validateForm() {
 if(_.trim(this.addusermodel.firstname) == "") {
   ////
 }
}

in spec file am using this code 

describe('validateForm', () => {
    it('Form should validate', () => {   
      component.addusermodel.firstname = "wrwer";
      component.validateForm();
    });
  });

But when i executing the function from spec file am getting this error TypeError: Cannot read property 'trim' of undefined

Solution

  • Import lodash like this

    import * as _ from "lodash"; instead of import _ from 'lodash';
