Unit test for a custom validator and AbstractControl value

[louis745]

Hello everyone,

I try to unit test this validator and I wonder to to give a value to the AbstractControl.  Thanks for your precious help.

My validator

export class VerifierNombresValidator {

    static plage(min: number, max: number): ValidatorFn {

        return (c: AbstractControl): { [key: string]: boolean } | null => {

             if ((c.value) && c.value >= min && c.value <= max) {

                return null;

            }

            return { 'plage': true };        

        };

    }

}

My unit test (but not working) :

  it('plage pour la valeur 3', () => {

    let validatorFn = VerifierNombresValidator.apply(88);

    let control = { value: '6' }

   

    VerifierNombresValidator.arguments(control as AbstractControl);

    let result =  VerifierNombresValidator.plage(1,5);

   

    expect(result['plage']).toBeUndefined();

  });

solution: 

 Just pass the AbstractControl param as inner function

it('plage pour la valeur 3', () => {

let control = { value: '6' }

    let result =  VerifierNombresValidator.plage(1,5)(control as AbstractControl);

    expect(result['plage']).toBeUndefined();

 });
