assert.notEqual(actual, expected[, message])


严格断言模式

assert.notStrictEqual() 的别名。

旧版断言模式

稳定性: 3 - 旧版: 改为使用 assert.notStrictEqual()

使用 != 运算符测试浅层强制不相等。 NaN 是特殊处理的,如果双方都是 NaN,则视为相同。

import assert from 'node:assert';

assert.notEqual(1, 2);
// OK

assert.notEqual(1, 1);
// AssertionError: 1 != 1

assert.notEqual(1, '1');
// AssertionError: 1 != '1'const assert = require('node:assert');

assert.notEqual(1, 2);
// OK

assert.notEqual(1, 1);
// AssertionError: 1 != 1

assert.notEqual(1, '1');
// AssertionError: 1 != '1'

如果值相等,则抛出 AssertionError,其 message 属性设置为等于 message 参数的值。 如果未定义 message 参数,则分配默认错误消息。 如果 message 参数是 Error 的实例,则将抛出错误而不是 AssertionError

Strict assertion mode

An alias of assert.notStrictEqual().

Legacy assertion mode

Stability: 3 - Legacy: Use assert.notStrictEqual() instead.

Tests shallow, coercive inequality with the != operator. NaN is specially handled and treated as being identical if both sides are NaN.

import assert from 'node:assert';

assert.notEqual(1, 2);
// OK

assert.notEqual(1, 1);
// AssertionError: 1 != 1

assert.notEqual(1, '1');
// AssertionError: 1 != '1'const assert = require('node:assert');

assert.notEqual(1, 2);
// OK

assert.notEqual(1, 1);
// AssertionError: 1 != 1

assert.notEqual(1, '1');
// AssertionError: 1 != '1'

If the values are equal, 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.
