strictEqual() 断言使用严格相等运算符 (===) 提供了最严格的类型和值比较。assert.equal() 可用于测试非严格相等。assert.notStrictEqual() 可用于显式测试严格不等式。变更日志在QUnit 1.1 之前,这种方法被称为assert.same().QUnit 1.3 中删除了别名。
substring、getDate、catch 等是常用的 JavaScript API,接下来的几篇文章将对 V8 中 API 的设计思想、源码和关键函数进行讲解,并通过例子讲解 JavaScript 在 V8 中的初始化、运行方式,以及它与解释器、编译器、字节码之间的关系。 本文讲解 API Equal 和 StrictEqual 的设计与实现。 2 Equal 和 StrictEqual 的...
not.toStrictEqual({ name: 'Flaming Sizzler', price: 899, }); }); The object literals that fail are the same, therefore error. The Pizza type’s shape is strictly equal to the object literal, but it’s type is made optional in the test context. One more thing with toEqual is ...

Then we are passing both the objects as actual and expected to the Node.js assert.notDeepStrictEqual() function and also passed a text to the message parameter.Open Compiler const assert = require('assert'); var Movie1 = { Name : 'RRR', Director : 'Rajamouli', Boxoffice : { "2022...
If two objects, or their child objects, are not equal (both in value and type), an error is thrown and the program is terminated: var assert = require('assert');var x = { a : { n: 0 } };var y = { a : { n: 0 } };var z = { a : { n: '0' } };assert.deepSt...
