test('should validate the length of an string', () => {
  let rules = validationRulesBuilder({
    type: 'string',
    constrains: [
      {
        method: 'length',
        params: {
          value: 4,
          message: 'Invalid String length',
        },
      },
      {
        method: 'nullable',
      },
    ],
  });

  // or

  rules = mongoFormValidationRulesRepo.getRulesByFormId(1);

  expect(validateWithRules(null, rules).isValid()).toBe(true);
  expect(validateWithRules('', rules).getErrors()).toEqual(['Invalid String length']);
  expect(validateWithRules('som', rules).getErrors()).toEqual(['Invalid String length']);
  expect(validateWithRules('some string', rules).getValue()).toEqual('some string');
});
