Make FactoryBot factories go faster
Faster Factory finds FactoryBot factories and replaces them with faster methods.
It prefers FactoryBot.build_stubbed over FactoryBot.build over FactoryBot.create.
It doesn't change your tests in any other way.
It changes one occurrence at a time, then runs the localized test for that change.
If the tests pass, it commits the change.
If they fails, it reverts the change.
Largely inspired by factory_faster by Tom Copeland.
Add this line to your application's Gemfile:
gem 'faster_factory'And then execute:
bundle
Or install it yourself as:
gem install faster_factory
Highly encouraged requirement: git
Faster Factory uses the test && commit || revert (TCR) methodology
for trying a small change, running the tests, then keeping the change if the tests pass,
or throwing the change away if the tests fail/error.
Because of this, it really works best to use Faster Factory in the context of a git repository.
Highly encouraged: only use this on a feature/topic branch, not master.
That way, if something goes sideways in an unexpected way, you can rollback the changes,
throw them away, or use git bisect to find the first bad commit.
Work in progress:
Display Faster Factory help options.
faster_factory help
faster_factory -h
faster_factory --help
Run Faster Factory on all files in spec/ or test/,
auto-correcting and committing the changes that succeed.
faster_factory
Run Faster Factory on all files on only specified folder or files, auto-correcting and committing the changes that succeed.
faster_factory path/to/folder/or/file
TODO
Run Faster Factory with a custom git commit message. The default commit message are:
[TCR] Replace FactoryBot.create with FactoryBot.build in {{file}}[TCR] Replace FactoryBot.build with FactoryBot.build_stubbed in {{file}}
faster_factory --message "Makes {{file}} tests run faaaaster"
TODO
Run Faster Factory with a different test strategy.
By default, Faster Factory only runs the localized test around the change.
Eg, rspec spec/user_spec.rb:37, if the change is on line 37
If you prefer to run more tests with each change, you can.
Options are: line, file, all.
faster_factory --strategy file
You can combine strategies with a comma to try one first, then double check with something larger.
Eg, line,file will run rspec spec/user_spec.rb:37, then if it passes rspec spec/user_spec.rb.
Eg, line,all will run rspec spec/user_spec.rb:37, then if it passes rspec.
faster_factory --strategy file,all
Run Faster Factory without committing successful changes to git.
TODO
faster_factory --no-git
TODO
Run Faster Factory without keeping changes. Instead, generate a report of successful changes.
faster_factory --dry-run
After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
