My test is failing with “Migrations are pending”. As migrations should be run automatically, this would seem to be a bug.

It seems that the migration failed (still not sure why; it succeeds on my machine on the same database). The CI log does not report the error from the failed migration.

I am having the same issue. Everything builds fine on my environment, but not with Circle CI. And when I try to run

- bundle exec rake db:migrate RAILS\_ENV=test I am getting errors that the tables already exist. I noticed it creates the database schema by running - bundle exec rake db:create db:schema:load --trace And it loads the whole schema, so why is it even asking for migrations?

This probably isn’t the right way to fix this but for now I commented out ActiveRecord::Migration.maintain\_test\_schema! in Rails\_Helper for RSpec and it worked. I don’t understand why it’s trying to run the migrations when Circle CI does a rake db:create and loads the schema. There is nothing to migrate when creating a new db from the schema… I’m sure there might be ramifications down the line that I’ll run into but at least rspec is running now.

I found workaround with adding this to my circle.yml file -  
database:  
override:  
- bundle exec rails db:create; bundle exec rails db:migrate; bundle exec rails db:migrate RAILS\_ENV=test

This configuration runs successfully in circleci.

```
machine:
      ruby:
        version: 2.3.1
    dependencies:
      pre:
        - gem install bundler
      post:
        - bundle exec rake assets:precompile
    database:
      override:
        - bundle exec rake db:drop
        - bundle exec rake db:create RAILS_ENV=test
        - bundle exec rake db:migrate RAILS_ENV=test
    test:
      post:
        - bundle exec rake test
```
