[英]Rails + Rspec: How to test what a rake task “puts” / “print”?
I have a rake task that merely loops through all my products and increments a counter if the product saves. 我有一个rake任务,该任务只循环遍历我所有的产品,如果产品保存,则增加一个计数器。 It then prints out that counter.
然后打印出该计数器。 How do I test what number it
puts
? 如何测试它什么号码
puts
?
task(:resave_every_product => :environment) do
total_products = 0
counter = 0
all_products = Product.find(:all)
puts "done loading all products"
puts "starting resaving..."
all_products.each do |product|
puts "current product is #{product.id}" if (counter%1000 == 0)
counter += 1 if product.save
end
puts "done resaving products."
puts "total products - #{all_products.size}"
puts "products resaved - #{counter}"
end
如果您愿意从使用puts切换到Logger(除非您有特定的使用理由,否则建议这样做),可以在RSpec中测试输出,如下所示:
Rails.logger.should_receive(:info).with('done loading all products')
