Our style guide says that we should [keep lines under 80 characters](https://github.com/alphagov/styleguides/blob/master/ruby.md#general), and here you can see one reason why - the long line hides the conditional. What about refactoring to:
```ruby
unless path == '/' || @site.global_http_status.present?
  mapping = row.find(:css, '.action')
  path = site_mapping_find_path(@site, path: path, return_path: site_hits_path(@site))
  expect(mapping).to have_link('', href: path)
end
```
