Issues with deep include and partial matches in associative array

[am11]

I am trying to figure out the best way to use .deep and .include. According to #1009 (comment), it seems like latest version of chai.js should work with partial matches.

Here is a similar sample to what I am trying to achieve https://jsfiddle.net/whm06h05/ (setup with latest versions of chai and mocha as of today):

'use strict';

mocha.setup("bdd");
chai.should();

describe('Include tests', () => {
  const array = [];
  array.push({a: 11.1, b: 'blah'});
  array.push({a: 12.1});

  it('should work with deep and exact object graph', () =>
    array.should.deep.include({a: 12.1})); // works
  
  it('should work without deep and exact object graph', () =>
    array.should.include({a: 12.1}));      // doesn't work
  
  it('should work with deep and partial object graph', () =>
    array.should.deep.include({a: 11.1})); // doesn't work
  
  it('should work without deep and partial object graph', () =>
    array.should.include({a: 11.1}));      // doesn't work
});

mocha.run();

With the latest version of chai, is there a way to test partial match; certain member of object in an array matches a value?

Hey @am11 thanks for the issue.

At current there is no way to do partial matching. deep should check all properties exhaustively, and so what you're hoping for with that code is not yet implemented. You should subscribe to #644 which is our tracking issue for implementing some kind of partial match.

I'll close this issue, as we should keep #644 as the main tracking issue for this feature.
