私的Railsのメモ

# 概要
私的なRailsのメモ。
頻繁に利用はしないが、時々やり方が気になりそうなところを追加していく予定。かなり初歩的なところばかりですが悪しからず

# Test
## Railsのデフォルトテストの結果に色付け
minitest-reporters gemを利用

```test/test_helper.rb
ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../../config/environment', __FILE__)
require 'rails/test_help'

## ここから
require "minitest/reporters"
Minitest::Reporters.use!
## ここまで追加

class ActiveSupport::TestCase
  # Setup all fixtures in test/fixtures/*.yml for all tests in alphabetical
  # order.
  fixtures :all

  # Add more helper methods to be used by all tests here...
end
```

## スタックトレースを簡略化？
テスト実行時に、失敗した場合の余計なトレースを簡略化してくれる？

```config/initializers/backtrace_silencers.rb
 # Be sure to restart your server when you modify this file.

# You can add backtrace silencers for libraries that you're using but don't
# wish to see in your backtraces.
Rails.backtrace_cleaner.add_silencer { |line| line =~ /rvm/ } # ここだけ修正

# You can also remove all the silencers if you're trying to debug a problem
# that might stem from framework code.
# Rails.backtrace_cleaner.remove_silencers!
```

## Guardでテスト自動化

```
$ bundle exec guard init
```

```Guardfile.
# 全部追加

# Defines the matching rules for Guard.
guard :minitest, spring: true, all_on_start: false do
  watch(%r{^test/(.*)/?(.*)_test\.rb$})
  watch('test/test_helper.rb') { 'test' }
  watch('config/routes.rb')    { integration_tests }
  watch(%r{^app/models/(.*?)\.rb$}) do |matches|
    "test/models/#{matches[1]}_test.rb"
  end
  watch(%r{^app/controllers/(.*?)_controller\.rb$}) do |matches|
    resource_tests(matches[1])
  end
  watch(%r{^app/views/([^/]*?)/.*\.html\.erb$}) do |matches|
    ["test/controllers/#{matches[1]}_controller_test.rb"] +
    integration_tests(matches[1])
  end
  watch(%r{^app/helpers/(.*?)_helper\.rb$}) do |matches|
    integration_tests(matches[1])
  end
  watch('app/views/layouts/application.html.erb') do
    'test/integration/site_layout_test.rb'
  end
  watch('app/helpers/sessions_helper.rb') do
    integration_tests << 'test/helpers/sessions_helper_test.rb'
  end
  watch('app/controllers/sessions_controller.rb') do
    ['test/controllers/sessions_controller_test.rb',
     'test/integration/users_login_test.rb']
  end
  watch('app/controllers/account_activations_controller.rb') do
    'test/integration/users_signup_test.rb'
  end
  watch(%r{app/views/users/*}) do
    resource_tests('users') +
    ['test/integration/microposts_interface_test.rb']
  end
end

# Returns the integration tests corresponding to the given resource.
def integration_tests(resource = :all)
  if resource == :all
    Dir["test/integration/*"]
  else
    Dir["test/integration/#{resource}_*.rb"]
  end
end

# Returns the controller tests corresponding to the given resource.
def controller_test(resource)
  "test/controllers/#{resource}_controller_test.rb"
end

# Returns all tests for the given resource.
def resource_tests(resource)
  integration_tests(resource) << controller_test(resource)
end
```

```\.gitignore
# See https://help.github.com/articles/ignoring-files for more about ignoring
# files.
#
# If you find yourself ignoring temporary files generated by your text editor
# or operating system, you probably want to add a global ignore instead:
#   git config --global core.excludesfile '~/.gitignore_global'

# Ignore bundler config.
/.bundle

# Ignore the default SQLite database.
/db/*.sqlite3
/db/*.sqlite3-journal

# Ignore all logfiles and tempfiles.
/log/*.log
/tmp

# ここ追加
# Ignore Spring files.
/spring/*.pid
```

```:Gemfile
# 追加
gem 'hirb'
gem 'hirb-unicode'
```

```
bundle install
