How to Compare the Rails 3 Test Suite

I want to optimize the test suite. First I need to know where the time is being spent. At a minimum, I want to know how much time is spent on each test.

I came across this gem https://github.com/timocratic/test_benchmark , but is no longer supported.

Please note that my goal is to compare the test suite, not the application.

Is there any other stone that I could use?

  • Rails
  • Rspec
  • Capybara

Rspec includes a minimum functional profiler. Have you looked at him? ( blogging tutorial for rspec1 but still valid for rspec2 )

Basically, if you specify -p , then you will get a list of the slowest 10 tests.

Are you familiar with the unix time command? If you just want to see how long your test suite has been running, you can simply add a time command:

 time rake spec

After rspec exits, you should see something like

 Finished in 5.31 seconds 195 examples, 0 failures, 27 pending real 0m26.580s user 0m14.085s sys 0m2.168s

Of course, it is assumed that you are on the * nix platform :-)
