If you are defining your function:

<pre><code>function test() {};
</code></pre>

Then, this is equivalent to:

<pre><code>window.test = function() {} /* (in the browser) */
</code></pre>

So <code>spyOn(window, 'test')</code> should work.

If that is not, you should also be able to:

<pre><code>test = jasmine.createSpy();
</code></pre>

If none of those are working, something else is going on with your setup.

I don't think your <code>fakeElement</code> technique works because of what is going on behind the scenes. The original globalMethod still points to the same code. What spying does is proxy it, but only in the context of an object. If you can get your test code to call through the fakeElement it would work, but then you'd be able to give up global fns.

There is 2 alternative which I use (for jasmine 2)

This one is not quite explicit because it seems that the function is actually a fake.

<pre><code>test = createSpy().and.callFake(test); 
</code></pre>

The second more verbose, more explicit, and "cleaner":

<pre><code>test = createSpy('testSpy', test).and.callThrough();
</code></pre>

-> <a href="https://github.com/jasmine/jasmine/blob/3140d5fb957008f7e166b917636ab507fc809a95/src/core/base.js#L64">jasmine source code</a> to see the second argument

blocks|key|636557|text|我的答案与@FlavorScape略有不同，因为我在导入的模块中只有一个(默认导出)函数，我执行了以下操作：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|636558|import+*+as+functionToTest+from+'whatever-lib';

const+fooSpy+=+spyOn(functionToTest,+'default');|code-block|syntax|javascript|636559|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

My answer differs slightly to @FlavorScape in that I had a single (default export) function in the imported module, I did the following:

<pre><code>import * as functionToTest from 'whatever-lib';

const fooSpy = spyOn(functionToTest, 'default');
</code></pre>

The approach we usually follow, is as follows:
<code>utils.ts</code> file for all global utilities:
<pre><code>function globalUtil() {
 // some code
}
</code></pre>
<code>abc.component.ts</code>:
<pre><code>function foo {
 // some code
 globalUtil(); // calls global function from util.ts
}
</code></pre>
While writing a Jasmine test for <code>function foo ()</code>, you can spy on the globalUtil function as follows:
<code>abc.component.spec.ts</code>:
<pre><code>import * as SharedUtilities from 'util.ts';

it('foo', () =&gt;
{
 const globalUtilSpy = jasmine.createSpy('globalUtilSpy');
 spyOnProperty(SharedUtilities, &quot;globalUtilSpy&quot;).and.returnValue(globalUtilSpy);
 
 foo();
 expect(globalUtilSpy).toHaveBeenCalled();
});
</code></pre>

I guess it's the easiest way:
<pre class="lang-js prettyprint-override"><code>const funcSpy = spyOn(myFunc, 'call');
</code></pre>

I'm new to Jasmine and have just started using it. I have a library js file with lots of functions which are not associated with any object (i.e. are global). How do I go about spying on these functions?

I tried using window/document as the object, but the spy did not work even though the function was called. I also tried wrapping it in a fake object as follows :

<pre><code>var fakeElement = {};
fakeElement.fakeMethod = myFunctionName;
spyOn(fakeElement, "fakeMethod");
</code></pre>

and test with

<pre><code>expect(fakeElement.fakeMethod).toHaveBeenCalled();
</code></pre>

This does not work either as the spy did not work

Using Jasmine to spy on a function without an object

我是Jasmine的新手，刚刚开始使用它。我有一个js库文件，里面有很多函数，这些函数与任何对象都没有关联(也就是说，它们是全局的)。我该如何监视这些函数？我尝试使用window/document作为对象，但即使调用了该函数，间谍也无法工作。我还尝试将其包装在一个伪对象中，如下所示：var fakeElement = ...
