Function strict

  • Expects the string input not to match the regular expression.

    import assert from '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.
