ActiveSupport::DeprecationTestHelper

A test helper that removes ActiveSupport::Deprecation noise from being interlaced in your test output. Instead this gem collects any and all deprecation warnings that occur during your tests, and succinctly reports them at the end of the test run.

Installation

Add this line to your application's Gemfile:

gem 'activesupport-deprecation_test_helper'

And then execute:

$ bundle

Or install it yourself as:

$ gem install activesupport-deprecation_test_helper

Usage

Basic Configuration

In order to capture and report all deprecation warnings at the end of the test run, use one of the following methods for configuration.

Configuring for Supported Test Frameworks

Currently the following test frameworks are supported out of the box:

• Minitest (:minitest)
• RSpec (:rspec)

In order to configure you test runs in Minitest add the following to your test_helper.rb

require 'active_support/deprecation_test_helper'
ActiveSupport::DeprecationTestHelper.configure(:minitest)

And for RSpec add the following to your spec_helper.rb after your RSpec.configure block:

require 'active_support/deprecation_test_helper'
ActiveSupport::DeprecationTestHelper.configure(:rspec)

Configuring for Unsupported Test Frameworks

If you are using an unsupported test framework and would like to use this gem, you'll need to add the following pieces to your test setup.

1. Include ActiveSupport::DeprecationTestHelper into ActiveSupport::Deprecation using the following

require 'active_support/deprecation_test_helper'
ActiveSupport::Deprecation.include ActiveSupport::DeprecationTestHelper

1. Report all unexpected warnings at the end of the test run with

ActiveSupport::DeprecationTestHelper.report_unexpected_warnings

Expected Deprecation Warnings

If you have some deprecations warnings that you're not going to resolve, and would like to omit them from the test run report, you can do the following

ActiveSupport::DeprecationTestHelper.allow_warning("The full deprecation warning string")

Or you can use a regex if you would like to match a series of deprecation warnings

ActiveSupport::DeprecationTestHelper.allow_warning(/will be removed from Rails 6\.0/)

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
