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

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

参数

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

期望 string 输入与正则表达式不匹配。

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

如果值确实匹配，或者如果 string 参数属于 string 以外的其他类型，则会引发 AssertionError 且 message 属性集等于 message 参数的值。如果 message 参数未定义，则分配默认错误消息。如果 message 参数是 Error 的实例，那么它将被抛出而不是 AssertionError 。
