使用Minitest的Rails，如何使用rake运行每次测试时自动运行RuboCop？

当我运行以下命令时，我希望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... Inspecting 9 files ......... 9 files inspected, no offenses detected Run options: --seed 55148 # Running: ................... Finished in 1.843280s, 10.3077 runs/s, 34.7207 assertions/s. 19 runs, 64 assertions, 0 failures, 0 errors, 0 skips
