Creating rspec tests
Authenticate anonymous users viewing mustdos
Test anonymous users are asked to sign in/up after being redirected to sign in page
Prompt user to create mustdo if they have none
Cleared up failing model spec. Deleting a user will now delete their mustdos.
Feature spec coverage for user views mustdos list with incomplete mustdos only
Improve language of user views mustdo spec a little
MustdosController#show action not used, remove artifacts
Remove :show route for mustdos
Remove unused update action of MustdosController
Remove pending spec for edit action that doesn't exist
Use the local mustdo instance we went to the trouble of putting in the view. Plus avoid instantiating Models in templates (prefer doing Model.new in controllers).
Test coverage for MustdosController#create
User create mustdo displays new mustdo in list test coverage and introduce sign_in_and_view_mustdos method
Commit of changes conflicts to mustdo controller spec file
