doesNotMatch(value: string,regExp: RegExp,message?: string | Error,): void
Expects the string input not to match the regular expression.
import assert from 'node:assert/strict'; assert.doesNotMatch('I will fail', /fail/); // AssertionError [ERR_ASSERTION]: The input was expected to not match the ... assert.doesNotMatch(123, /pass/); // AssertionError [ERR_ASSERTION]: The "string" argument must be of type string. assert.doesNotMatch('I will pass', /different/); // OK
If the values do match, or if the string argument is of another type thanstring, 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 an Error then it will be thrown instead of the AssertionError.
