Method: RSpec::Core::Configuration#prepend_before

Defined in:
lib/rspec/core/configuration.rb

#prepend_before(scope = nil, *meta, &block) ⇒ void

Adds block to the start of the list of before blocks in the same scope (:example, :context, or :suite), in contrast to #before, which adds the hook to the end of the list.

See Hooks#before for full before hook docs.

This method differs from Hooks#prepend_before in only one way: it supports the :suite scope. Hooks with the :suite scope will be run once before the first example of the entire suite is executed. Conditions passed along with :suite are effectively ignored.
