Question

I am using factory girl to create a model with inventory_count = 3. In my test, I want to test a case for when inventory_count = 0..so here’s what I did:

before(:each) do
  @user = FactoryGirl.create(:user)
  @piece = FactoryGirl.create(:piece)
  @lineup = @user.lineup
end

it 'should have status \'Waiting List\' if the piece doesn\'t have available inventory' do
  @piece.available_count = 0
  @lineup.pieces << @piece
  piece_lineup = @lineup.piece_lineups.find_by_piece_id(@piece.id)
  piece_lineup.set_status
  piece_lineup.status.should == 'Waiting List'
end

I put a debugger after @piece.available_count = 0 and it is = 0, but when it gets down to the next line it switches back to the old value. I tried adding a .save to @piece but it still didn’t work. Am i doing something wrong? Should I be creating the new value model in factorygirl instead of trying to do it on the fly?

Answer 1

I believe it would be better practice to write:

@piece = FactoryGirl.create(:piece, :available_count => 0)

to create a piece model with its count already 0.

Also, you’re question begins mentioning inventory_count. Did you actually mean available_count? Just want to make sure you didn’t have a typo.
