Rails: Reset the test database
A solution that worked for me to recreate and populate the test database from scratch
bin/rake db:schema:dump RAILS_ENV=test bin/rake db:drop RAILS_ENV=test bin/rake db:create RAILS_ENV=test bin/rake db:test:prepare
INFO
bin/rake db:setup # Create the database, load the schema, and initialize with the seed data bin/rake db:reset # Drop the database + (rake db:setup)
