expect-immutable

immutable.js extension for mjackson/expect

setup

npm install expect-immutable

api

• expect(ImmutableIterable).toEqualImmutable(ImmutableIterable)
• expect(ImmutableIterable).toNotEqualImmutable(ImmutableIterable)

usage

import { Map, List } from 'immutable';
import expect from 'expect'
import expectImmutable from 'expect-immutable';

expect.extend(expectImmutable);

describe('expect-immutable', () => {
  it('will work', () => {
    expect(Map({ a: 1 })).toEqualImmutable(Map({ a: 1 }));
    expect(Map({ a: 1 })).toNotEqualImmutable(Map({ a: 2 }));

	expect(List([1])).toEqualImmutable(List([1]));
	expect(List([1])).toNotEqualImmutable(List([1, 2]));
  });
});

todo

Currently, only Map and List are supported by test cases, but any Immutable Iterable should work.

thanks

Thanks to mjackson for writing the awesome expect library.

Thanks to algolia/expect-jsx who I based heavily off of.
