I have a set of examples that should run with a specific set of records
in the database.
Since setting those records is an expensive operation I'd like to
perform it just once per context.
For example:
context 'sample tree' do
before(:all) { create_tree_records }
example ...
end
The problem with this is that while before(:each) and the examples will
run in a transaction that will be rolled back at the end of each
example, that won't happen to the records created/modified by the
before(:all) block.
It seems my database vendor (PostgreSQL) supports nested transactions
(savepoints):
http://www.postgresql.org/about/
I should also notice that I'm using Sequel and it seems that
transactions are reentrant in Sequel:
http://cheat.errtheblog.com/s/sequel/
Database#transaction is re-entrant:
DB.transaction do # BEGIN issued only here
DB.transaction
dataset << {:first_name => 'Inigo', :last_name => 'Montoya'}
end
end # COMMIT issued only here
So, this logic wouldn't work for me. I need a save point in a
before(:all), so that I'd restore it on a before(:each).
Is there any recommendation to make this work in my specs?
Thanks in advance,
Rodrigo.
