内容简介：Additionally,Contributed by ConorDavenport -

assert.CallTracker is a new experimental API that allows to track and later verify the number of times a function was called. This works by creating a CallTracker object and using its calls method to create wrapper functions that will count each time they are called. Then the verify method can be used to assert that the expected number of calls happened: 

const assert = require('assert');

const tracker = new assert.CallTracker();

function func() {}
// callsfunc() must be called exactly twice before tracker.verify().
const callsfunc = tracker.calls(func, 2);
callsfunc();
callsfunc();

function otherFunc() {}
// The second parameter defaults to `1`.
const callsotherFunc = tracker.calls(otherFunc);
callsotherFunc();

// Calls tracker.verify() and verifies if all tracker.calls() functions have
// been called the right number of times.
process.on('exit', () => {
  tracker.verify();
});

Additionally, tracker.report() will return an array which contains information about the errors, if there are any: 

const assert = require('assert');

const tracker = new assert.CallTracker();

function func() {}
const callsfunc = tracker.calls(func);

console.log(tracker.report());
/*
[
  {
    message: 'Expected the func function to be executed 1 time(s) but was executed 0 time(s).',
    actual: 0,
    expected: 1,
    operator: 'func',
    stack: Error
        ...
  }
]
*/

Console groupIndentation option

The Console constructor ( require('console').Console ) now supports different group indentations.

This is useful in case you want different grouping width than 2 spaces.

const { Console } = require('console');
const customConsole = new Console({
  stdout: process.stdout,
  stderr: process.stderr,
  groupIndentation: 10
});

customConsole.log('foo');
// 'foo'
customConsole.group();
customConsole.log('foo');
//           'foo'
