## Reporting Bugs

Please use our [bug report template][1].

## Development

Install gems with `bundle exec appraisal install`.

Testing is a little awkward because the test suite:

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

### 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 appraisal ar-5.0 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 appraisal ar-5.0 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
DB=postgres RAILS_ENV=test bundle exec rake db:drop db:create db:migrate
DB=postgres RAILS_ENV=foo bundle exec rake db:drop db:create db:migrate
DB=postgres RAILS_ENV=bar bundle exec rake db:drop db:create db:migrate
cd ../..

# Run tests
DB=postgres bundle exec rake
DB=postgres bundle exec appraisal ar-5.0 rake
```
