assert.notEqual(actual, expected[, message])
严格断言模式
旧版断言模式
assert.notStrictEqual() 。使用抽象相等比较(!=)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。
const assert = require('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
assert.notStrictEqual() instead.Tests shallow, coercive inequality with the Abstract Equality Comparison
(!= ). NaN is special handled and treated as being identical in case both
sides are NaN.
const assert = require('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.
