Documentation Grafana k6 JavaScript API jslib testing Non-Retrying Assertions toEqual()

toEqual()

The toEqual() method asserts that the actual value is deeply equal to the expected value, performing recursive comparison of objects and arrays.

Syntax

JavaScript Copy

expect(actual).toEqual(expected);
expect(actual).not.toEqual(expected);

Parameters

Returns

Description

The toEqual() method performs deep equality comparison, recursively checking all properties of objects and elements of arrays. Unlike toBe(), it compares the content of objects rather than their references.

Use toEqual() when you want to assert that two values have the same structure and content, even if they are different objects in memory.

Usage

JavaScript Copy

import { expect } from 'https://jslib.k6.io/k6-testing/0.5.0/index.js';

export default function () {
  const user1 = { name: 'John', age: 30 };
  const user2 = { name: 'John', age: 30 };

  expect(user1).toEqual(user2);
  expect(user1).not.toBe(user2); // Different references
}
