Match object recursively (toMatchObject)

[ismay]

The discussion on recursive matching suggested here #1793 (comment) was never continued in the PR. As far as I can tell toMatchObject does not match recursively, but it would be nice if this was a possibility.

@ismay How do these examples adapted from the unit tests for toMatchObject compare to your expectations for recursive matching, pardon the pun :)

describe('toMatchObject', () => {
  it('matches recursively', () => {
    expect({
      a: 'b',
      t: {
        x: {
          r: 'r'
        },
        z: 'z'
      }
    }).toMatchObject({
      t: {
        x: {
          r: 'r'
        }
      }
    });
    expect({
      a: 'b',
      t: {
        x: {
          r: 'r'
        },
        z: 'z'
      }
    }).not.toMatchObject({
      t: {
        l: {
          r: 'r'
        }
      }
    });
  });
});

Maybe I should have worded it differently, but what I mean is it matching:

x: {
  r: 'r'
}

In the test you mentioned, even though that's nested under t. To me that would be useful when testing if an object needs to contain something but you don't care about where exactly.

@ismay are you willing to ship a PR on that?

[ismay]

Definitely willing, but no time atm I'm afraid.

Cool, take your time, no worries! 🙂
