function assert.notStrictEqual
Usage in Deno
import assert from "node:assert"; const { notStrictEqual } = assert;
notStrictEqual(actual: unknown,expected: unknown,message?: string | Error,): void
Tests strict inequality between the actual
and expected
parameters as
determined by Object.is()
.
import assert from 'node:assert/strict'; assert.notStrictEqual(1, 2); // OK assert.notStrictEqual(1, 1); // AssertionError [ERR_ASSERTION]: Expected "actual" to be strictly unequal to: // // 1 assert.notStrictEqual(1, '1'); // OK
If the values are strictly equal, an AssertionError
is thrown with amessage
property set equal to the value of the message
parameter. If themessage
parameter is undefined, a
default error message is assigned. If themessage
parameter is an instance of an Error
then it will be thrown
instead of the AssertionError
.
