ruby - rspec failing error: expected false to respond to `false?` -

i running portion of test:

 describe dictionary    before      @d = dictionary.new    end      'can check whether given keyword exists'         @d.include?('fish').should be_false       end 

with code:

class dictionary   def initialize     @hash = {}   end     def add(new_entry)     new_entry.class == string ? @hash[new_entry] = nil : new_entry.each { |noun, definition| @hash[noun] = definition}       end     def entries     @hash    end     def keywords     @hash.keys   end    def include?(word)     if @hash.has_key?(word)       true     else        false     end    end  end  

i don't know i'm doing wrong, tests keep failing , saying this:

> 1) dictionary can check whether given keyword exists >      failure/error: @d.include?('fish').should be_false >        expected false respond `false?` 

i confused @ error since seems giving correct answer. appreciate if take few minutes tell me what's wrong code. thank tons.

if browse rspec expectations 2.99 , rspec expectations 2.14 , search section - truthiness , existentialism, find

expect(actual).to be_true  # passes if actual truthy (not nil or false) expect(actual).to be_false # passes if actual falsy (nil or false) # ............... # ... 

but of browse rspec expectations 3.0 , above method names got changed -

expect(actual).to be_truthy    # passes if actual truthy (not nil or false) expect(actual).to true      # passes if actual == true expect(actual).to be_falsey    # passes if actual falsy (nil or false) # ........... #...... 

it seems in 3.0, , using method exist prior version. getting error.

i put code in test.rb file below :-

class dictionary   def initialize     @hash = {}   end     def add(new_entry)     new_entry.class == string ? @hash[new_entry] = nil : new_entry.each { |noun, definition| @hash[noun] = definition}       end     def entries     @hash    end     def keywords     @hash.keys   end    def include?(word)     if @hash.has_key?(word)       true     else        false     end    end  end 

and spec/test_spec.rb file -

require_relative "../test.rb"  describe dictionary   before     @d = dictionary.new   end    'can check whether given keyword exists'     @d.include?('fish').should be_false   end end 

now running code console, , works :

arup@linux-wzza:~/ruby> rspec -v 2.14.8 arup@linux-wzza:~/ruby> rspec spec .  finished in 0.00169 seconds 1 example, 0 failures

now changing code in spec/test_spec.rb file :-

require_relative "../test.rb"  describe dictionary   before     @d = dictionary.new   end    'can check whether given keyword exists'     @d.include?('fish').should be_falsey   end end 

and again run test :-

arup@linux-wzza:~/ruby> rspec -v 2.14.8 arup@linux-wzza:~/ruby> rspec spec f  failures:    1) dictionary can check whether given keyword exists      failure/error: @d.include?('fish').should be_falsey      nomethoderror:        undefined method `falsey?' false:falseclass      # ./spec/test_spec.rb:9:in `block (2 levels) in <top (required)>'  finished in 0.00179 seconds 1 example, 1 failure  failed examples:  rspec ./spec/test_spec.rb:8 # dictionary can check whether given keyword exists arup@linux-wzza:~/ruby>

now, mentioned in 3.0.0.beta1 / 2013-11-07 changelog

rename be_true , be_false be_truthy , be_falsey. (sam phippen)
