Development Notes

When developing against crecto, the database must exist prior to testing. There are migrations for each database type in spec/migrations, and references on how to migrate then in the .travis.yml file.

Create a new file spec/repo.cr and create a module name Repo to use for testing. There are example repos for each database type in the spec folder: travis_pg_repo.cr, travis_mysql_repo.cr, and travis_sqlite_repo.cr

When submitting a pull request, please test against all 3 databases.
