Rakefile

task :test do
  puts "run tests"
end
 
namespace :build do
  task :dev do
    puts "build dev"
  end
 
  task :test do
    puts "build test"
  end
end
 
namespace :ci do
  # "test" here would invoke "ci:test". "rake:test" forces the global task
  task :dev => ["build:dev", "rake:test"]
  task :test => ["build:test"]
end
