FactoryFaster

FactoryFaster optimizes your Rails app's FactoryGirl usage by replacing create with build where it's safe to do so.

Installation

Add this line to your application's Gemfile in the 'development' group:

gem 'factory_faster'

And then execute:

$ bundle

Usage

Process just one file with:

bundle exec script/rails runner "FactoryFaster::Batch.new('test/unit/foo_test.rb').process"

Or if you want to include the gem but not require it in your Gemfile:

bundle exec script/rails runner "require 'factory_faster' ; FactoryFaster::Batch.new('test/unit/foo_test.rb').process"

Or use a glob to process lots of files:

bundle exec script/rails runner "FactoryFaster::Batch.new('test/unit/*.rb').process"

The output will be something like this:

foo> $ bundle exec script/rails runner "FactoryFaster::Batch.new('test/unit/foo_test.rb').process"
Processing test/unit/foo_test.rb

2 of 2 could be replaced, so replacing those

BUGS / TODO

Adding a new test to a file invalidates all the skip line numbers after the addition. Subsequent runs then get both the old and the new line numbers, so gradually more and more lines get skipped.

FactoryFaster will miss the case there a test case has multiple calls to Factory.create and if more than one of then has to be switched to Factory.build in order to trigger an error.

FactoryFaster depends on sed to replace the code. It could use plain old Ruby instead.

FactoryFaster doesn't skip commented out lines.
