Rails 5, Rspec: Environment data not found in the schema

Question

After upgrading a Rails app to Rails 5, running RSpec tests gives me the following error:

rails aborted!
ActiveRecord::NoEnvironmentInSchemaError: 

Environm         


        

Answer 1

For me, this error was followed by a similar one asking for a migration.

This did the trick: rails db:migrate RAILS_ENV=test
