Why is JBuilder not returning a response body in JSON when testing RSPEC

Question

When testing a JSON response from an RSPEC controller test using DHH\'s JBuilder, my response.body is always \"{}\". It works fine in development/production modes AND when

Answer 1

You could find a solution from https://github.com/rails/jbuilder/issues/32

So in rspec/spec_helper.rb

RSpec.configure do |config|
  # https://github.com/rails/jbuilder/issues/32
  config.render_views = true
end

After above option are added, JSON result will show via jbuilder renderer

Answer 2

For anyone that is having the same issue. I have figured it out.

You must call render_views within the controller tests you are doing. If you do that, you should then see a response.body with your JSON contained :)
