puts 是在命令行里面打印输出。使用 puts 进行临时输出、调试和验证代码逻辑。
Rails.logger 是在日志里面打印输出。使用 Rails.logger 记录应用程序的运行时信息、错误和重要事件。
eg :
puts
test "should get index width paramater" do
# 打印出所有的 Manager 记录
puts Manager.all.inspect
assert_equal 3, Manager.count
assert Manager.count == 3
get managers_url, params: { email: "admin@email.com" }
assert_equal 1, assigns(:managers).size
assert_response :success
end
运行命令行输出：
$ bundle exec rails test test/controllers/managers_controller_test.rb:18
Run options: --seed 24542
