How to find how long my rake task is taking

Question

I am using Rails 3.0.10 . I am using mac.

I tried this

time  rake spec/models/user_spec.rb

Then I tried

time (rake spec/models/user_spec.rb)

This one took longer but I did not see my test output.

What is the right way to figure out how long my rake is taking.

Answer 1

您应该能够使用'time'为任何命令计时，并使用ruby解释器直接运行单个测试：

time ruby spec/models/user_spec.rb
