How to use the notDeepEqual function from assert

Find comprehensive JavaScript assert.notDeepEqual code examples handpicked from public code repositorys.

assert.notDeepEqual is a function in the Node.js assert module that tests whether two objects are not deeply equal, meaning they have at least one property with a different value or structure.

// 8. The non-equivalence assertion tests for any deep inequality.

    fail(actual, expected, message, 'notDeepEqual', assert.notDeepEqual);

How does assert.notDeepEqual work?

The assert.notDeepEqual function is a part of the Node.js assert module, which provides a set of assertion functions for writing unit tests in a Node.js application. When you call the assert.notDeepEqual function, you pass in two objects that you want to compare for inequality. The function tests whether the two objects are not deeply equal, meaning they have at least one property with a different value or structure. If the two objects are not deeply equal, the assert.notDeepEqual function does nothing and the test passes. However, if the two objects are deeply equal, the function throws an error with a message that describes the failure. The assert.notDeepEqual function works by recursively comparing the properties of the two objects. If a property is an object or an array, the function recursively compares the properties of the sub-objects or sub-arrays. The assert.notDeepEqual function is often used in unit tests to verify that a function or module is returning the expected result. By comparing the actual result with the expected result using assert.notDeepEqual, you can ensure that the function or module is working correctly and that the expected result is not simply a coincidence. Overall, the assert.notDeepEqual function provides a convenient way to test whether two objects are not deeply equal in a Node.js application, helping you catch bugs and ensure that your code is working as expected.

const assert = require("assert");

// Test that two objects are not deeply equal
const obj1 = { a: 1, b: [2, 3] };
const obj2 = { a: 1, b: [2, 4] };
assert.notDeepEqual(obj1, obj2);

In this example, we first require the assert module in our Node.js application. We then define two objects, obj1 and obj2, that have the same a property but different b properties. The b property of obj1 is an array with the values [2, 3], while the b property of obj2 is an array with the values [2, 4]. We then use the assert.notDeepEqual function to test that obj1 and obj2 are not deeply equal. Since the b properties of the two objects have different values, the assertion passes and the test succeeds. If the two objects had been deeply equal, the assert.notDeepEqual function would have thrown an error with a message that describes the failure. Overall, this example demonstrates how to use assert.notDeepEqual to test that two objects are not deeply equal in a Node.js application.
