Usage
First, add require option to .rspec
-r rspec-power_assert
Use ExampleGroup.it_is_asserted_by or ExampleGroup#is_asserted_by
describe Object do
it_is_asserted_by { a == b }
it do
is_asserted_by { a == b }
end
end
Config
verbose_successful_report
RSpec::PowerAssert.verbose_successful_report = true
If it set true, Successful Example reports with power_assert outputs.
If it set false, Successful Example reports without power_assert outputs.
Default is true.

On RSpec-3.3 or later, support aggregate_failures
(Thanks sue445)
2) RSpec::PowerAssert Array#map When use aggregate_failures should be called be is_asserted_by with 3 times
