OCIError insufficient privileges while testing with rails

Question

I have a problem with my unit tests in rails and found no idea how to solve it.

If i run rake test:units i get the following error:

rake aborted!
OCIError: ORA-01031: insufficient privileges: CREATE TABLE 
"SCHEMA MIGRATIONS" ("VERSION" VARCHAR(255) NOT NULL)
stmt.c:312:in oci8lib_191.so
Tasks: TOP => test:units => test:prepare => db:test:prepare => db:abort_if_pedning_migrations

My current Gemfile is

source 'http://rubygems.org'
gem 'rails', '~> 3.1.12'

gem 'ruby-oci8', '~> 2.0.4'
gem 'activerecord-oracle_enhanced-adapter', '~> 1.3.2'

gem 'ruby-plsql', '~> 0.4.3'
gem 'sqlite3'
gem 'thin'

group :assets do  
    gem 'sass-rails',   '~> 3.1.7'  
    gem 'coffee-rails', '~> 3.1.1'  
    gem 'uglifier',     '>= 1.0.3'
end
gem 'jquery-rails'

database.yml contains the following data:

test:
  adapter: oracle_enhanced
  database: service_name
  username: db_admin
  password: test
  host: name_of_host
  port: 1531

The same data as in database.yml works for the database connection in oracle sql developer.

Answer 1

I got it working by adding the environment variable and running

rake test:units RAILS_ENV=test

So actually rails was accessing the wrong database.
