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.[:key] == :some_value && some_global_condition
      raise "some message"
    end
    ex.run         # run delegates to ex.call
  end
end
