Documentation of callIds

[rluvaton]

Would you be open for PR to document the callIds property?

The reason it's needed is because let's say I have 2 function fn1 and fn2

And want to test assert the following

fn1();
fn2();
fn1();
fn2();

Currently I can't do that with the current assertions but I want to open it so I can add support for other assertions library to use (my sinon-jest-marchers specifically)

Sorry this was just lying here for forever, but I just never noticed it. You have been able to check exactly this since Sinon 1. This works fine using the SpyCall API:

const assert = require("assert");

const fn1 = sinon.spy();
const fn2 = sinon.spy();

fn1();
fn2();
fn1();
fn2();

const fn1Call0 = fn1.getCall(0);
const fn1Call1 = fn1.getCall(1);
const fn2Call0 = fn2.getCall(0);
const fn2Call1 = fn2.getCall(1);

assert(fn1Call0.calledBefore(fn2Call0));
assert(fn2Call0.calledBefore(fn1Call1));
assert(!fn2Call0.calledBefore(fn1Call0));

As such, I don't think we need to expose the underlying callId? I'll close for now, unless there is something I am missing.
