Rspec feature test - issue for render blank page

Question

I don't know why but chrome renders blank page after completion of first it block.

create_account_spec.rb :

If I write all the expect in on it block it works fine.

Thanks in advance.

Answer 1

The issue for this specific question is that your visit call is in the wrong place, but your bigger overall issue is that you're writing your feature tests like unit tests.

Every it block is a separate test, and assuming you're using the standard Capybara rspec integration one of the last things done is to visit about:blank. This will occur after your after :all block. Because of this the visit of the page you're testing should occur either in your before :all block or in the individual tests themselves. Additionally, since the DB is/should be reset between each test (it/scenario block) signing out isn't usually necessary.

before :all do
  visit '/' # Alternatively you could move this to your login_as method
  GUI.login_as :auto_admin
  find('#employer_model_screen a').send_keys :enter
end

# Not generally necessary for tests of the type you show
# after :all do
#   GUI.sign_out
#   visit '/'
# end

Now, the bigger issue is that you're testing a whole "feature" yet testing for a single visual element in each test. This means that to see if the company name is shown it has to create a company, create a user, have a browser visit a page, then login, then check the name. Next it wants to check country type so it has to again create a company, create a user, have a browser visit the same page, then login, then check the country type. If you continue writing your feature tests like that they're very quickly going to take hours if not days to run. If the purpose of your check is that all the company info is shown then it should be one it/scenario

it "shows the company info" do
  expect(page).to have_css('td.name'.text: company.name)
  expect(page).to have_css('td.workflow-type', text: company.workflow_type)
  ...
end

Note also the use of the capybara provided matchers, rather than .text with eq, which will make your tests a lot more stable once you start having ajax/asynchronous actions and page updates since it provide waiting/retrying behavior to the checks. (You should also stay away from all/first whenever possible since they have severe limitations on dynamic pages)
