How do I add gem 'minitest' to my test helper?

Question

I am new to Ruby on Rails and testing. When I run rake test I get the following error:

/Users/jarvis/.rvm/gems/ruby-1.9.2-p180@rails3tutorial/gems/r         


        

Answer 1

uninstall your minitest first. gem uninstall minitest.

if you are using turn make sure the version is less 0.8.3

put those code to your bottom of your Gemfile

group :test do
  gem 'turn', '< 0.8.3'
  gem 'minitest'
end

then run

bundle install 

Answer 2

Edit your Gemfile so that the gem is specified under the test group, like so:

group :test do
  gem "minitest"
end
