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

• actual <any>

• expected <any>

• message <string> | <Error>

严格断言模式

\Strict assertion mode

assert.notStrictEqual() 的别名。

\An alias of assert.notStrictEqual().

旧版断言模式

\Legacy assertion mode

使用 != 操作符 测试肤浅的强制性不平等。NaN 是特殊处理的,如果双方都是 NaN,则视为相同。

\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'拷贝

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。

\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.
