Overview

`Tapioca::Compilers::Dsl::ActiveRecordFixtures` decorates RBIs for test fixture methods that are created dynamically by Rails.

For example, given an application with a posts table, we can have a fixture file

~~~yaml first_post:

author: John
title: My post

~~~

Rails will allow us to invoke `posts(:first_post)` in tests to get the fixture record. The generated RBI by this generator will produce the following

~~~rbi # test_case.rbi # typed: true class ActiveSupport::TestCase

sig { params(fixture_names: Symbol).returns(T.untyped) }
def posts(*fixture_names); end

end ~~~
