“Could not find a valid mapping for #” only on second and successive tests

Question

I\'m trying to write a request test that asserts that the proper links appear on the application layout depending in whether a user is logged in or out. FWIW, I\'m using Dev

Answer 1

In my case this was a problem with Devis's confirm! method. So instead of doing this (Minitest::Test code):

setup do
  @admin = create(:admin).confirm!
end

I have done this:

setup do
  @admin = create(:admin)
  @admin.confirm!
end

And it worked :)
