@rafaelfranca You can currently do

```ruby
ActiveRecord::FixtureSet::RenderContext.include MyHelpers
```

I think we can get to where you want by

```ruby
class ActiveRecord::FixtureSet
  def self.context
      ActiveRecord::FixtureSet::RenderContext
  end
end
```

If I read [this](https://github.com/rails/rails/blob/master/activerecord/lib/active_record/fixtures.rb#L739) right, Fixtures is deprecated, so what you wrote would work and output a deprecation warning. The line below is slightly longer, but would work as is.

```ruby
FixtureSet.context.include MyHelpers
```

What do you think?
