Development

Testing is a little awkward because the test suite:

1. Supports three major versions of rails: 3, 4, 5
2. Contains a "dummy" rails app with three databases (test, foo, and bar)
3. Supports three different RDBMS': sqlite, mysql, and postgres

Test against rails 3:

bundle exec appraisal ar3 rake

Run tests with sqlite:

# Create the appropriate database config. file
rm test/dummy/config/database.yml
DB=sqlite bundle exec rake prepare

# If this is the first test run ever, create databases
cd test/dummy
RAILS_ENV=test bundle exec rake db:setup
RAILS_ENV=foo bundle exec rake db:setup
RAILS_ENV=bar bundle exec rake db:setup
cd ../..

# Run tests
DB=sqlite bundle exec rake

Run tests with mysql:

# Create the appropriate database config. file
rm test/dummy/config/database.yml
DB=mysql bundle exec rake prepare

# If this is the first test run ever, create databases
cd test/dummy
RAILS_ENV=test bundle exec rake db:setup
RAILS_ENV=foo bundle exec rake db:setup
RAILS_ENV=bar bundle exec rake db:setup
cd ../..

# Run tests
DB=mysql bundle exec rake

Run tests with postgres:

# Create the appropriate database config. file
rm test/dummy/config/database.yml
DB=postgres bundle exec rake prepare

# If this is the first test run ever, create databases.
# Unlike mysql, use create/migrate instead of setup.
cd test/dummy
RAILS_ENV=test bundle exec rake db:create
RAILS_ENV=test bundle exec rake db:migrate
RAILS_ENV=foo bundle exec rake db:create
RAILS_ENV=foo bundle exec rake db:migrate
RAILS_ENV=bar bundle exec rake db:create
RAILS_ENV=bar bundle exec rake db:migrate
cd ../..

# Run tests
DB=postgres bundle exec rake
