Question

brief.rb

# encoding: utf-8 
class Brief < ActiveRecord::Base 
    belongs_to :project 
    validates_numericality_of :duration, :only_integer => true, :less_than_or_equal_to => 15, :greater_than_or_equal_to => 5, :unless => Proc.new{ |b| b.project.project_type.express_project } 
end 

brief_spec.rb

require 'spec_helper' 

describe Brief do 

    before(:all) do 
    @project =Factory(:project) 
    @brief=Factory.build(:brief,:project => @project) 
    end 

    context 'non-specific tests' do 

    subject { @brief } 

    it { should belong_to(:project) } 

    it { should validate_presence_of(:project} 

    end 
end 

Это не моя краткая модель и краткая спецификация file.But Я не понять, как можно Я тестирую validates_numericality_of , если part.Can кто-нибудь попробовал это раньше?

Answer 1

условия использования и испытания различных условий

например.

context "when duration is more than 5 but less than 15" do 
    before do 
    subject.duration = 10 
    end 
    it { should validate_presence_of(:project) } 
end 
context "when duration is more than 15" do 
    before do 
    subject.duration = 20 
    end 
    it { should_not validate_presence_of(:project) } 
end
