Show runtime for each rspec example

Question

currently I'm running more than 1k examples and it's taking a long time to complete (more than 20 minutes!!!).

I'd like to identify which examples are the ones taking more time to complete, is there any way to run rspec and return the time each example takes to complete(individually)? I'm using rspec 1.3.0 and rspec-rails 1.2.3

You can use profiling to list your 10 slowest examples:

spec -p spec/*/*_spec.rb --colour --format profile

If you run this on a specific test suite you can get the 10 slowest examples from a smaller subset of examples:

spec -p spec/models/user_spec.rb --format profile

Newer Versions of Rspec

For newer versions of rspec you should use the --profile option:

rspec spec/ --profile         | (shows the 10 slowest examples)
rspec spec/ --profile 2       | (shows the 2  slowest examples)

Thanks! I think it should be easy to add support for the N slowest examples! – jpemberthy Feb 01 '11 at 13:56

The "profile" format is not present in the version of Rspec I'm using, 2.11.0 – David N. Welton Aug 28 '12 at 14:28

I think in the newer versions of RSpec you only need to use the `--profile` option. – Pan Thomakos Aug 31 '12 at 23:06
you can have those params globally in ~/.rspec - a '--param stuff' per line – jobwat Dec 03 '14 at 22:56
