使用Minitest的Rails，如何设置RuboCop，使其在每次使用rake运行测试时自动运行

Question

当我运行以下命令时，我希望RuboCop在运行测试之前检查我指定的应用程序目录：

bundle exec rake test

Answer 1

我向lib/tasks/test.rake:添加了以下任务

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
