Step 1 - Testing ElasticSearch - spec_helper.rb
# This file was generated by the `rails generate rspec:install` command. Conventionally, all
# specs live under a `spec` directory, which RSpec adds to the `$LOAD_PATH`.
# The generated `.rspec` file contains `--require spec_helper` which will cause this
# file to always be loaded, without a need to explicitly require it in any files.
#
# Given that it is always loaded, you are encouraged to keep this file as
# light-weight as possible. Requiring heavyweight dependencies from this file
# will add to the boot time of your test suite on EVERY test run, even for an
# individual file that may not need all of that loaded. Instead, make a
# separate helper file that requires this one and then use it only in the specs
# that actually need it.
#
# The `.rspec` file also contains a few flags that are not defaults but that
# users commonly want.
#
# See http://rubydoc.info/gems/rspec-core/RSpec/Core/Configuration

Thanks a lot for sharing the 3 codepieces! Very valuable.

thanks for your gist.
in config.around :each you need to traverse searchable models not only during creating indexes but after example.run as well, so the refined example should look something like:

SEARCHABLE_MODELS = [ModelName]
config.around :each, elasticsearch: true do |example|
  SEARCHABLE_MODELS.each do |model|
    model.__elasticsearch__.create_index!(force: true)
    model.__elasticsearch__.refresh_index!
  end

  example.run

  SEARCHABLE_MODELS.each do |model|
    model.__elasticsearch__.client.indices.delete index: model.index_name
  end
end
