Mysql::Error: SAVEPOINT active_record_1 does not exist: ROLLBACK TO SAVEPOINT active_record_1 (ActiveRecord::StatementInvalid)

Possible Reason 1: parallel_tests - running more processes than features

If you run old versions of parallel_tests Show archive.org snapshot with more processes than you have Cucumber features, you will get errors like this in unexpected places:

This is a bug caused by multiple processes running the same features on the same database.

The bug is fixed in versions 0.6.18+ Show archive.org snapshot .

Possible Reason 2: You are running parallel tests but you are using an (probably old) database.yml which is not setup for parallel tests.

Checkout the card below to see how to set it up properly:

Possible Reason 3: (Tests) You are using database_cleaner with the :transaction strategy, while use_transactional_fixtures is true

Turn transactional fixtures off -- database_cleaner will take care of this. See How to set up database_cleaner for Rails with Cucumber and RSpec.
