CollectionIncluding

CollectionIncluding

Validates if value matches an Object with expected keys and values matching the given expectations. The value may also contain other keys with arbitrary values not defined in pattern(equivalent of Meteor's Match.ObjectIncluding).

*Returns:** true if value is matching explicit CollectionIncluding pattern or implicit expectation as plain object even with arbitrary keys, else throws.

import { expect } from 'chai';

import { validate, ValidationError, CollectionIncluding } from 'typend';

expect(validate({ foo: 'foo' }, new CollectionIncluding({ foo: 'foo' }))).to.be

.true;

expect(

validate({ foo: 'foo', bar: 'bar' }, new CollectionIncluding({ foo: 'foo' }))

).to.be.true;

expect(() =>

validate(

{ foo: 'NOT_foo', bar: 'bar' },

new CollectionIncluding({ foo: 'foo' })

)

).to.throw(ValidationError);

// You can omit defining explicit pattern(`CollectionIncluding`) by passing plain object in loose mode:

validate({ foo: 'foo' }, { foo: 'foo' }, false);
