ruby-on-rails - 使用 Minitest 的 Rails，如何设置 RuboCop 在每次使用 rake 运行测试时自动运行？

Question

当我运行以下命令时，我想要 RuboCop在测试运行之前检查我指定的应用程序目录:

bundle exec rake test

Answer 1

我将以下任务添加到 lib/tasks/test.rake :

require 'rubocop/rake_task'

# Add additional test suite definitions to the default test task here
namespace :test do
  desc 'Runs RuboCop on specified directories'
  RuboCop::RakeTask.new(:rubocop) do |task|
    # Dirs: app, lib, test
    task.patterns = ['app/**/*.rb', 'lib/**/*.rb', 'test/**/*.rb']

    # Make it easier to disable cops.
    task.options << "--display-cop-names"

    # Abort on failures (fix your code first)
    task.fail_on_error = false
  end
end

Rake::Task[:test].enhance ['test:rubocop']

结果:

$ bundle exec rake test
Running RuboCop...
