# Using test-prof's before_all block to safely wrap shared data in a transaction,
# shared_let acts similarly to +let(:foo) { value }+ but initialized the value only once
# Changes _within_ an example will be rolled back by database cleaner,
# and the creation is rolled back in an after_all hook.
#
# Caveats: Set +reload: true+ if you plan to modify this value, otherwise Rails may still
# have cached the local value. This will perform a database select, but is much faster
# than creating new records (especially, work packages).
#
# Since test-prof added `let_it_be` this is only a wrapper for it
# before_all / let_it_be fixture
def shared_let(key, reload: true, refind: false, &block)
let_it_be(key, reload:, refind:, &block)
end
# Defines an object to be used by default for all FactoryBot association
# matching they key name.
#
# The object is created only once in the example group, and reused for each
# example. Under the hood, it uses +let_it_be+ and +FactoryDefault+ from the
# test_prof gem.
#
# For instance, when creating work packages with +create(:work_package)+, a new
# user gets created for each create work package. To reuse the same user for all
# created work packages, in your example group add:
#
# shared_association_default(:user) { create(:user) }
#
def shared_association_default(key, factory_name: key, &block)
# unique let identifier to prevent clashes
let_it_be(key, reload: true, &block)
before do
set_factory_default(factory_name, send(key))
end
end
# Use this to boost performance in tests creating lots of work packages.
