assert.notEqual(actual, expected[, message])
严格断言模式
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
.
