I'm running a simple unit test to validate that ActiveRecord raises an exception when I try and update a column with a duplicate foreign key.
Inside the unit test,
charge.time_logs << time_logs(:first)
will generate
ActiveRecord::StatementInvalid: Mysql::Error: #23000Duplicate entry '20' for key 2: UPDATE time_logs SET `task_id` = 1, `date_created` = NULL, `time_charge_id` = 20, `hours` = 2.0, `log_entry` = NULL WHERE id = 2
However,
assert_raise ActiveRecord::StatementInvalid do charge.time_logs << time_logs(:first) end
will generate
<ActiveRecord::StatementInvalid> exception expected but none was thrown.
What am I doing wrong?
