Validate doesn't work in Angular 9?

Hi Marc,

I created a new project using Angular 9 and added the code for validation I found in the documentation. The test fails as no error is returned. I am wondering what am I doing wrong here? Am I missing something?

I understand that this may have something to do with Angular.

Repo with the code: https://github.com/ericjeker/marshal-validation

Steps:

ng new marshal-validation
npm install @marcj/marshal reflect-metadata
# create the page.spec.ts file
ng test

page.spec.ts

import {f, validate, ValidationError} from '@marcj/marshal';

class Page {
    @f
    name: string;

    @f
    age: number;
}

describe('Page', () => {

  it('should fail', () => {

  	const errors = validate(Page, {name: 'peter'});
	expect(errors.length).toBe(1);
	expect(errors[0]).toBeInstanceOf(ValidationError);
	expect(errors[0].path).toBe('age');
	expect(errors[0].message).toBe('Required value is undefined');

  });

  it('should not fail', () => {

  	const errors = validate(Page, {name: 'gabriel', age: 42});
	expect(errors.length).toBe(0);

  });

});
