javascript - 如何在 qunit 测试中比较两件事？

Question

Qunit 测试以检查两个事物是否相等。

我有 2 个变量要比较。var currentVector = scene.up;var expectedVector = new THREE.Vector3( 0, 1, 0 );

他们返回以下内容:

assert.equal( currentVector, expectedVector, "Vector y is up in current scene"); 

但是控制台返回

来自documentation for equal

The equal assertion uses the simple comparison operator (==) to compare the actual and expected arguments.

在 JavaScript 中，一个对象不等于另一个对象，除非两者是相同的引用。

const o = {a: 1}
console.log('o == {a: 1}:', o == {a: 1})

const t = o
console.log('o == t:', o == t)

只需使用 deepEqual相反

assert.deepEqual(currentVector, expectedVector, "...")
