assert.notDeepStrictEqual(actual, expected, message?): void

Attributes

actual:any

expected:any

message:string | Error | Function

Tests for deep strict inequality. Opposite of assert.deepStrictEqual().

import assert from 'node:assert/strict';

assert.notDeepStrictEqual({ a: 1 }, { a: '1' });
// OK

JavaScript

const assert = require('node:assert/strict');

assert.notDeepStrictEqual({ a: 1 }, { a: '1' });
// OK

JavaScript

If the values are deeply and strictly equal, an AssertionError is thrown with a message property set equal to the value of the message parameter. If the message parameter is undefined, a default error message is assigned. If the message parameter is an instance of Error then it will be thrown instead of the AssertionError.
