test-loop - Continuous testing for Ruby with fork/eval
test-loop is a fast continuous testing tool for Ruby that continuously detects and tests changes in your Ruby application in an efficient manner, whereby it:
- Absorbs the test execution overhead into the main Ruby process.
- Forks to evaluate your test files directly and without overhead.
It relies on file modification times to determine what parts of your Ruby
application have changed and then uses Rake's String#pathmap
function to
determine which test files in your test suite correspond to those changes.
Features
Supports Test::Unit, RSpec, or any other testing framework that is utilized by your application's
test/test_helper.rb
andspec/spec_helper.rb
files.Tests CHANGES in your Ruby application; does NOT run all tests every time.
Reabsorbs test execution overhead if the test or spec helper file changes.
Mostly I/O bound, so you can have it always running without CPU slowdowns.
Implemented in less than 40 (SLOC) lines of code! :-)
