Node.js assert.doesNotMatch(string, regexp[, message])用法及代碼示例

assert.doesNotMatch(string, regexp[, message])

參數

• string <string>
• regexp <RegExp>
• message <string> | <Error>

期望 string 輸入與正則表達式不匹配。

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/);
// OKconst assert = require('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

如果值確實匹配，或者如果 string 參數屬於 string 以外的其他類型，則會引發 AssertionError 且 message 屬性集等於 message 參數的值。如果 message 參數未定義，則分配默認錯誤消息。如果 message 參數是 Error 的實例，那麽它將被拋出而不是 AssertionError 。
