Since bd62389, isolate test of `test_serialized_attribute_works_under_concurrent_initial_access` fails. ``` $ ./bin/test -w test/cases/serialized_attribute_test.rb -n test_serialized_attribute_works_under_concurrent_initial_access Using sqlite3 Run options: -n test_serialized_attribute_works_under_concurrent_initial_access --seed 32129 # Running: E Error: SerializedAttributeTest#test_serialized_attribute_works_under_concurrent_initial_access: ActiveRecord::StatementInvalid: SQLite3::SQLException: no such table: ``` If duplicate an unloaded model, it seems that method invocation for that class is not guaranteed. Use the original class to avoid it.
