function assert.match
Usage in Deno
import assert from "node:assert";
match(value: string,regExp: RegExp,message?: string | Error,): void
Expects the string
input to match the regular expression.
import assert from 'node:assert/strict';
assert.match('I will fail', /pass/);
// AssertionError [ERR_ASSERTION]: The input did not match the regular ...
assert.match(123, /pass/);
// AssertionError [ERR_ASSERTION]: The "string" argument must be of type string.
assert.match('I will pass', /pass/);
// OK
If the values do not match, or if the string
argument is of another type than string
, an [AssertionError](../.././assert/~/assert.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](../.././assert/~/assert.AssertionError)
.
