Review Comment:
I can change this but I just want to highlight that this is a modified copy
of existing tests in this test class and this is the code style in the existing
tests.

> It can be dangerous taking class names as inputs from HTTP messages even if

> (validateResponse method).
> I can provide a PR that will highlight the issue.
