Description
The faker and ffaker APIs are mostly the same, although the API on ffaker keeps diverging with its users additions. In general, the only difference is that you need to:
ffaker alternatives and similar gems
Based on the "Fake Data" category.

Fabrication
DISCONTINUED. This project has moved to GitLab! Please check there for the latest updates. -
StringPattern
Generate strings supplying a simple pattern. Perfect to be used in test data factories. Validate if a text fulfills a specific pattern. Also you can use regular expressions (Regexp) to generate strings: `/[a-z0-9]{2,5}\w+/.gen`. Generate words in English or Spanish.

ffaker vs faker
The faker and ffaker APIs are mostly the same, although the API on ffaker keeps diverging with its users additions. In general, the only difference is that you need to:
gem install ffaker
and then
require 'ffaker'
Rails
- If using rails then add the gem to your development and test environments:
group :development, :test do
gem 'ffaker'
end
- and then run
bundle install
in your terminal/BASH/command line.
Why ffaker?
ffaker is a fork of faker, and was initially written in an effort to speed up a slow spec suite. Since those days faker has also been rewritten and the "speed" factor is probably irrelevant now. Bear in mind, if your spec suite is slow, chances are the generation of random data will probably not account for much of the run time.
Nowadays the code bases have diverged enough to make the two projects truly different: since ffaker creation, a lot of new API methods have been added through the generous contributions of people all over the world.
Hopefully some day faker and ffaker will join forces!
Contributors
A lot of people have contributed to ffaker. Check this list.
If you want to add new modules or localization data, use one of the directories for data files (or create a new one!).
const_missing is
overriden
for Faker modules, so if you try to use a constant that is not defined
in the module, the
override
will look for a data file matching the name of the constant. E.G.: the
first time someone accesses FFaker::Name::FIRST_NAMES
, a const of that
name will be set with data from ffaker/data/name/first_names
.
Using the same random seed as your tests
To get repeatable results in Minitest or Rspec, follow [these instructions](RANDOM.md#using-the-same-random-seed-as-your-tests).
Unique results
You can get unique value from any methods in FFaker like this:
FFaker::Name.unique.name
TODO
- Even though the API is pretty simple, better rdoc documentation would not hurt.
- Put all modules under their respective languages (E.G. EducationUS instead of just Education)
Note on Patches/Pull Requests
- Fork the project.
- Make your feature addition or bug fix.
- Add tests for it. This is important so I don't break it in a future version unintentionally.
- Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
- Send me a pull request. Bonus points for topic branches.
Release
- Bump version in
lib/version.rb
. - Update
Changelog.md
. - Tag with
v<major>.<minor>.<patch>
