Feature: Define example attribute
In order to streamline process
As an RSpec user
I want to easily define helper methods that act as a variable assignment
It is fairly common to start with a local variable in one example, use the same
local variable in the next, and then extract the declaration of that variable
to before(:each). This requires converting the locals to instance variables.
This feature streamlines the process by defining a helper method so you can extract
the duplication without having to change other references to the same variables
to @instance_variables.
Scenario:
Given a file named "counter_spec.rb" with:
"""
require 'spec/autorun'
class Counter
def initialize
@count = 0
end
def count
@count += 1
end
end
describe Counter do
let(:counter) { Counter.new }
it "returns 1 the first time" do
counter.count.should == 1
end
it "returns 2 the second time because the counter itself is cached by the 'assign' method" do
counter.count
counter.count.should == 2
end
end
"""
When I run "spec counter_spec.rb"
Then the stdout should include "2 examples, 0 failures"
