I recently discovered that bundler has a feature to create binstubs, so I decided to redo my benchmarks of running a single pending spec (but including the complete spec_helper for my project).
To create rspec binstubs:
1

Here are my findings:
Description | Command | Avg. Time (3 runs) | |
---|---|---|---|
Bundled Rspec | bundle exec rspec |
61.76 s | |
Binstubs | bin/rspec |
50.24 s | |
Binstubs + Spork | bin/rspec –drb |
17.43 s | |
Binstubs + Spork + Nailgun | jruby –ng -S bin/rspec –drb |
6.65 s |
It is still slower than I would like, but well worth the effort. Since I didn’t want to remember the specific invocation depending on what I have running, I have a script that will use binstubs, nailgun and/or spork if available:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 |
