将mock的call()对象与 一起使用时assert_has_calls，我很难断言已使用给定字符串并在末尾附加了未知值。

例如：

被测代码：

mystring = 'a known string with an unknown value: {0}'.format(unknown_value)
method_to_call(mystring)

当前测试代码：

with mock.patch('method_to_call') as mocked_method:
  calls = [call('a known string with and unknown value: {0}'.format(mock.ANY)]
  call_method()
  mocked_method.assert_has_calls(calls)

这给了我一些类似的东西：

AssertionError: Calls not found.
Expected: [call('a known string with and unknown value: <ANY>')]

如何断言给定的字符串已传递给方法但允许未知值？
