uninitialized constant Rspec

Question

I created a new rails application and followed the installation instructions for rspec-rails here - https://github.com/rspec/rspec-rails I then created (copied from the interwebs) the following module in my app/lib directory.

require 'openssl' require 'base64'  module Cipher   def self.encrypt(key, data)     data += 'A' # Add 'A' suffix to support empty data     cipher(:encrypt, key, data)   end    def self.decrypt(key, text)     data = cipher(:decrypt, key, text)     data[0...-1] # Remove the 'A' suffix   end    def self.encrypt_base64(key, data)     blowfish_string = self.encrypt(key, data)     Base64.encode64(blowfish_string)   end    def self.decrypt_base64(key, base64_string)     blowfish_string = Base64.decode64(base64_string)     self.decrypt(key, blowfish_string)   end    private    def self.cipher(mode, key, data)     cipher = OpenSSL::Cipher::Cipher.new('bf-cbc').send(mode)     cipher.key = Digest::SHA256.digest(key)     cipher.update(data) << cipher.final   end end 

Then I created the following spec file.

require 'rails_helper'  Rspec.describe Ciper do    describe "cipher encrypts data" do     let(:key) { 'secret key' }      it "encrypts a string" do       original = ''       encrypted = Cipher.encrypt(key, original)       decrypted = Cipher.decrypt(key, encrypted)       expect(decrypted).to equal original     end   end  end 

When I try to run the spec I get the following error

/Users/user/RubymineProjects/skeleton/spec/lib/cipher_spec.rb:3:in `<top (required)>': uninitialized constant Rspec (NameError)     from /Users/user/.rvm/gems/ruby-2.2.0/gems/rspec-core-3.2.0/lib/rspec/core/configuration.rb:1226:in `load'     from /Users/user/.rvm/gems/ruby-2.2.0/gems/rspec-core-3.2.0/lib/rspec/core/configuration.rb:1226:in `block in load_spec_files'     from /Users/user/.rvm/gems/ruby-2.2.0/gems/rspec-core-3.2.0/lib/rspec/core/configuration.rb:1224:in `each'     from /Users/user/.rvm/gems/ruby-2.2.0/gems/rspec-core-3.2.0/lib/rspec/core/configuration.rb:1224:in `load_spec_files'     from /Users/user/.rvm/gems/ruby-2.2.0/gems/rspec-core-3.2.0/lib/rspec/core/runner.rb:97:in `setup'     from /Users/user/.rvm/gems/ruby-2.2.0/gems/rspec-core-3.2.0/lib/rspec/core/runner.rb:85:in `run'     from /Users/user/.rvm/gems/ruby-2.2.0/gems/rspec-core-3.2.0/lib/rspec/core/runner.rb:70:in `run'     from /Users/user/.rvm/gems/ruby-2.2.0/gems/rspec-core-3.2.0/lib/rspec/core/runner.rb:38:in `invoke'     from /Users/user/.rvm/gems/ruby-2.2.0/gems/rspec-core-3.2.0/exe/rspec:4:in `<top (required)>'     from /Users/user/.rvm/gems/ruby-2.2.0/bin/rspec:23:in `load'     from /Users/user/.rvm/gems/ruby-2.2.0/bin/rspec:23:in `<top (required)>'     from -e:1:in `load'     from -e:1:in `<main>'  Process finished with exit code 1 Empty test suite. 

I'm not sure what I'm doing wrong here. Can anyone offer some insight on what I can try? Thanks!

Answer 1

From the error:

uninitialized constant Rspec (NameError) 

In your Cipher spec, you have misspelled RSpec as Rspec. Ruby identifiers are case-sensitive, and you haven't defined Rspec, hence the error.

Answer 2

I was getting this error because rubymine was trying to run "tests" instead of "rspecs". When I changed the run configuration to run an RSpec instead of a Test everything worked fine.
