Problem with before(:all)

Testing RSpec
1

I have a module with two methods for marshaling objects.
The following rspec code is used to test this module:

----- Start Code -----
require ‘…/code/fmutil.rb’
require ‘…/code/fmgrid.rb’
require ‘…/code/serial.rb’

start test of Serial Module

describe Serial do
describe “Given a grid with the block test pattern” do
before(:all) do
cfg01 = Fmconfig.new
grid01 = Grid.makeempty(cfg01,500,20)
cfg01.list[:cellhight].times do |y|
cfg01.list[:cellwidth].times do |x|
grid01[x,y].elevation = x+10*(y+1)
end
end
end
describe “restored serialized grid object” do
it “matches origional grid object.” do
grid02 = Grid.allocate
Serial.write(grid01,“testtemp01”)
grid02 = Serial.read(grid02,“testtemp01”)
grid01[9,9].elevation.should == grid02[9,9].elevation
end
end
end
end
----- End Code -----

But when I run it it seems that the Grid object created in the
before(:all) hook is not available to the example [see below].
Why is this?

----- Start Run -----
rich@richlaptop2:~/Documents/fakemap/rspec$ rspec serialgrid.rb

if you wanna share variables from before filters to specs, you need to
use
instance variables instead of local ones, example:

WRONG:

before :all do
myvar = 1
end

it “should do something” do
puts myvar # nil
end

RIGHT:

before :all do
@myvar = 1
end

it “should do something” do
puts @myvar # 1
end
