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


    严格断言模式

    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.
