How to find which rspec test is taking so long

问题

One (or a couple) of our tests are taking forever and we'd like to optimize them.

We have say 1000 tests so it's impractical for me to go through run each file.

Is there an easy to way to find the slow ones?

This is rspec 1.3

回答1:

In RSpec 2 and 3, you can use the --profile flag or add --profile to your .rspec file. This will track the top 10 slowest examples.

For RSpec 1, you can use --format o with spec command. It shows a text-based progress bar with profiling of 10 slowest examples. For more details see this.

rspec --profile -- path/to/file/spec.rb
