Id equality assertions for chai.
Ids come in lots of flavors. Sometimes they're strings, sometimes objects. Sometimes you'll find them at .id
, other times at ._id
. ChaId lets you test for equality by comparing string representations of ids, with minimal fretting about initial representation or location:
{_id: 'foo'}.should.have.id('foo')
'foo'.should.id({id: 'foo'})
{id: 'foo', bar: 2}.should.have.same.id({id: 'foo', baz: 3})
{_id: 'foo'}.should.not.have.same.id({_id: 'bar'})
{_id: 'foo'}.should.have.same.id({id: {toString: function() { return 'foo'}})
{_id: 'foo'}.should.have.id(new ObjectId('foo'))
You can also compare lists of objects by id:
[{id:'a'}, {id:'b'}].should.have.ids ['a', 'b']
['a', 'b'].should.be.ids ['a', 'b']
[{id:'a'}, {id:'b'}].should.have.same.ids [{id:'a'}, {id:'b'}]
[{id:'a'}, {id:'b'}].should.not.have.same.ids [{id:'b'}, {id:'a'}]
By default, order matters. To ignore order, chain unordered
:
[{id:'a'}, {id:'b'}].should.have.same.unordered.ids [{id:'b'}, {id:'a'}]
You can test for a subset of ids by chaining include
or contain
:
[{id:'a'}, {id:'b'}].should.include.same.ids [{id:'a'}]
Works well with MongoDB ObjectIds:
doc.should.have.id(new ObjectId())
doc.should.have.same.id(otherDoc)
(new ObjectId()).should.id(doc)
This is a plugin for the Chai Assertion Library. Install via npm.
npm install chaid
Use this plugin as you would all other Chai plugins.
var chai = require('chai')
, chaid = require('chaid');
chai.use(chaid);
