I am having some issue asserting attributes from FastAPI Depends class. The Depends have an attribute for saving your dependency:

class Depends:
    def __init__(dependency):
        self.dependency = dependency

The dependency attribute must be a callable (anything that implements __call__).
I am trying to replace this function in my test for something like:

assert_that(dependencies).extracting('dependency').is_equal_to([dependency_limiter])

However, as the dependency attribute is a callable, because the zero-args-method-call feature, the extracting method is calling dependency attribute instead of just returning it.

I think the behavior I described above would be better. What do you think?

I am submitting a PR in case you agree with me.
