如何使用通配符检查模拟调用? [英] How to check for mock calls with wildcards?

问题描述

我正在编写单元测试，并想检查具有函数对象的调用，如下所示:

I am writing unit tests, and want to check for a call which has a function object, like so:

call(u'mock', u'foobar', at 0x1ea99b0>, 10)

如何在不重现 lambda 的情况下检查 call() 是否具有我想要的所有参数?

How do I check that the call() has all the parameters I want, without reproducing the lambda?

我想澄清一下我正在使用这里的 mock 库:http://mock.readthedocs.org/en/latest/.我上面展示的 call 是对 MagicMock 对象的调用，我想使用 assert_has_calls 检查它.

I wanted to clarify that I am using the mock library from here: http://mock.readthedocs.org/en/latest/. The call I showed above is a call on a MagicMock object, which I want to check using assert_has_calls.

推荐答案

我终于知道如何做我想做的事了.基本上，当使用 assert_has_calls 时，我希望一个参数匹配而不管它是什么(因为我无法在测试期间每次都重新创建 lambda).

I finally found out how to do what I want. Basically, when using assert_has_calls, I wanted one parameter to match regardless of what it was (because I can't recreate the lambda every time during test).

这样做的方法是使用 mock.ANY.

The way to do it is to use mock.ANY.

因此，在我的示例中，这可以匹配调用:

So, in my example, this could match the call:

mocked_object.assert_has_calls([
   call('mock', 'foobar', mock.ANY, 10)
])
