class RSpec::Core::World

@api private

Internal container for global non-configuration data.

Attributes

example_groups[R]

@private

filtered_examples[R]

@private

non_example_failure[RW]

Used internally to signal that a failure outside of an example has occurred, and that therefore the exit status should indicate the run failed. @private

wants_to_quit[RW]

Used internally to determine what to do when a SIGINT is received.

traverse_example_group_trees_until(&block) click to toggle source

@private Traverses the tree of each top level group. For each it yields the group, then the children, recursively. Halts the traversal of a branch of the tree as soon as the passed block returns true. Note that siblings groups and their sub-trees will continue to be explored. This is intended to make it easy to find the top-most group that satisfies some condition.

# File lib/rspec/core/world.rb, line 108
def traverse_example_group_trees_until(&block)
  example_groups.each do |group|
