Class: RSpec::Core::Example::Procsy

Relationships & Source Files
Inherits: Object
Defined in: rspec-core/lib/rspec/core/example.rb

Overview

Note:

This class also exposes the instance methods of ::RSpec::Core::Example, proxying them through to the wrapped ::RSpec::Core::Example instance.

Wraps both a Proc and an ::RSpec::Core::Example for use in around hooks. In around hooks we need to yield this special kind of object (rather than the raw ::RSpec::Core::Example) because when there are multiple around hooks we have to wrap them recursively.

Examples:

RSpec.configure do |c|
  c.around do |ex| # Procsy which wraps the example
    if ex.metadata[:key] == :some_value && some_global_condition
      raise "some message"
    end
    ex.run         # run delegates to ex.call.
  end
end
