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
- If using rails then add the gem to your development and test environments:
group :development, :test do gem 'ffaker' end
- and then run
bundle installin your terminal/BASH/command line.
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!
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!).
for Faker modules, so if you try to use a constant that is not defined
in the module, the
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
Using the same random seed as your tests
To get repeatable results in Minitest or Rspec, follow these instructions.
You can ensure unique values are generated using the
ffaker will retry the generation
until an unique value if found.
::..name # ensures an unique value is returned for FFaker::Name
If an unique value cannot be generated within a maximum limit of retries for a generator
FFaker::UniqueUtils::RetryLimitExceeded error will be raised.
You can prevent exceeding the limit by clearing the record of used values (e.g. between tests):
::..clear # clears the used values for FFaker::Name ::. # clears the used values for all generators
- 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.
- To run all the tests:
- To run a single test:
rake test TEST=test/test_lorem_br.rb
- To run all the tests:
- 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.
- Bump version in
- Tag with
- Push it.
