jasmine toHaveBeenCalledWith partial matching
提问by Pwnna
With Jasmine, I could spy on methods and figure out the arguments. I want to be able to call toHaveBeenCalledWith(something, anything).
使用 Jasmine，我可以监视方法并找出参数。我希望能够打电话toHaveBeenCalledWith(something, anything)。
Let's say I want to spy on a method .on(event, callback). All I care about is if the eventis listened to rather than what the actual callback identity is. Is it possible to do this without writing a custom matcher? I don't see one.
假设我想监视一个方法.on(event, callback)。我所关心的是是否event监听了 ，而不是实际的回调标识是什么。是否可以在不编写自定义匹配器的情况下执行此操作？我一个都没有。

If you wish to test for specific things, you can do something like:
如果您想测试特定的东西，您可以执行以下操作：
expect(mockSomething.someMethod.mostRecentCall.args[0].pool.maxSockets).toEqual(50);
The syntax in Jasmine 2 is now:
Jasmine 2 中的语法现在是：
mockSomething.someMethod.calls.mostRecent().args[0]
