blocks|key|346709|text|我也遇到过类似的问题，其中一个数组被修改了。我将它用于$httpBackend，从中返回的对象实际上是一个包含数组的$promise对象(而不是Array对象)。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|346710|您可以通过创建一个toBeArray函数来创建一个jasmine匹配器来匹配数组：|346711|beforeEach(function()+{

I had a similar issue where one of the arrays was modified. I was using it for <code>$httpBackend</code>, and the returned object from that was actually a <code>$promise</code> object containing the array (not an <code>Array</code> object). 

You can create a jasmine matcher to match the array by creating a <code>toBeArray</code> function:

<pre><code>beforeEach(function() {
 'use strict';
 this.addMatchers({
 toBeArray: function(array) {
 this.message = function() {
 return "Expected " + angular.mock.dump(this.actual) + " to be array " + angular.mock.dump(array) + ".";
 };
 var arraysAreSame = function(x, y) {
 var arraysAreSame = true;
 for(var i; i &lt; x.length; i++)
 if(x[i] !== y[i])
 arraysAreSame = false;
 return arraysAreSame;
 };
 return arraysAreSame(this.actual, array);
 }
 });
});
</code></pre>

And then just use it in your tests like the other jasmine matchers:

<pre><code>it('should compare arrays properly', function() {
 var array1, array2;
 /* . . . */
 expect(array1[0]).toBe(array2[0]);
 expect(array1).toBeArray(array2);
});
</code></pre>

blocks|key|129035|text|为了便于记录，您可以随时使用JSON.stringify进行比较|type|unstyled|depth|inlineStyleRanges|entityRanges|data|129036|const+arr+=+[1,2,3];+expect(JSON.stringify(arr)).toBe(JSON.stringify([1,2,3]));+expect(JSON.stringify(arr)).toEqual(JSON.stringify([1,2,3]));|offset|length|style|CODE|129037|这是所有的品味，这也适用于复杂的文字对象|129038|entityMap^0|0|0|3X|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@$D|N|E|O|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|P|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|K|$]]

just for the record you can always compare using JSON.stringify

<code>
const arr = [1,2,3];
expect(JSON.stringify(arr)).toBe(JSON.stringify([1,2,3]));
expect(JSON.stringify(arr)).toEqual(JSON.stringify([1,2,3]));
</code>

It's all meter of taste, 
this will also work for complex literal objects

blocks|key|346823|text|如果数组具有某些值，则可以比较下面提到的数组|type|unstyled|depth|inlineStyleRanges|entityRanges|data|346824|it('should+check+if+the+array+are+equal',+function()+{
++++++++var+mockArr+=+[1,+2,+3];
++++++++expect(mockArr+).toEqual([1,+2,+3]);
+});|code-block|syntax|javascript|346825|但是，如果从某个函数返回的数组包含1个以上的元素，并且所有元素都为零，则使用|346826|expect(mockArray[0]).toBe(0);|346827|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

You can compare an array like the below mentioned if the array has some values

<pre><code>it('should check if the array are equal', function() {
 var mockArr = [1, 2, 3];
 expect(mockArr ).toEqual([1, 2, 3]);
 });
</code></pre>

But if the array that is returned from some function has more than 1 elements and all are zero then verify by using

<pre><code>expect(mockArray[0]).toBe(0);
</code></pre>

Is there a way in jasmine.js to check if two arrays are equal, for example:

<pre><code>arr = [1, 2, 3]
expect(arr).toBe([1, 2, 3])
expect(arr).toEqual([1, 2, 3])
</code></pre>

Neither seems to work.

Jasmine.js comparing arrays

JSON

在jasmine.js中有没有一种方法来检查两个数组是否相等，例如：arr = [1, 2, 3]expect(arr).toBe([1, 2, 3])expect(arr).toEqual([1, 2, 3])两种方法似乎都不管用。
