Re: [Rails] db:migrate error on test after Rails 4.2 update

Ruby on Rails Friday, January 30, 2015

If I run:
bundle exec rake db:drop db:create db:migrate
I get error that db:migrate needs to be run with RAILS_ENV=test
if I 
bundle exec rake db:drop db:create db:migrate RAILS_ENV=test
I get error regarding duplicate table again

If I delete db from postgres management screen then run
bundle exec rake db:drop db:create db:migrate RAILS_ENV=test
I can again run the test once, but the second time I get the error that migrations are pending and to run db:migrate RAILS_ENV=test

I wonder why the act of running a simple test trigges this migration message

I presume your development db is up to date (so running migrate on
that does nothing).
What happens if you recreate the test db and then run migrate on it?
Does the migrate run successfully?
