Rails rspec test wheter controller action define instance variable -

i have controller action:

def new   @team = team.new   @team.team_links.build end 

and want test action rspec. (i know works, because works should in application, specs failing.) here spec:

it "returns new team built in team_link"   'new'    team = assigns(:team)   team.should be_new_record   team.team_links.should_not be_empty # here fails end 

here error message:

 1) teamscontroller new returns @team , builds 1 team_link      failure/error: team.team_links.should_not be_empty        expected empty? return false, got true 

@team.team_links.build neither persist record nor instance variable, effect of line disappeared in view context.

you need assign instance variable testable in view:

# controller @team_link = @team.team_link.build  # rspec assigns(:team_link).should_not be_empty
