You shouldn't need an if in a test.

If you expect content_find to return an object, then assume it returns an object.

You know the length of the expected return value of self.storage.content_find (2), no need for a for loop that runs only twice.

(Because, if there is a bug in content_find that makes it return only a single element, the for loop will not run, and the test won't catch the bug)

You don't need to compare the length, assertCountEqual does it already.
