如何仅在Rails的测试环境中插入日志？

Question

I want to put some code ONLY in test environment, for example insert a line of log:

puts "Something in TEST"

What's the best way to do it?

Answer 1

Before Rails 2.x, the best way to get the current environment was using RAILS_ENV . Rails 2.x or later, Rails introduced the Rails module with method Rails.env . So you can use

Before 2.x: if RAILS_ENV == 'test'

After 2.x: if Rails.env.test?
