Fast Faker == Faker refactored. rubygems.org/gems/ffaker

A port of Perl’s Data::Faker library that generates fake data. rubygems.org/gems/faker

require 'ffaker'
Faker::Name.name => "Christophe Bartell"
Faker::Internet.email => "[email protected]"

Faker and Ffaker APIs are mostly the same, although the API on ffaker keeps growing with its users additions. In general, the only difference is that you need to:

gem install ffaker

and then

require 'ffaker'

instead of “faker” with only one f.

Ffaker was initially written in an effort to speed up a slow spec suite. Bear in mind, if your spec suite is slow, chances are the generation of random data will not account for much of the run time.

Since then, the original faker gem has become faster (at the moment it did not seem it was maintained). Nevertheless, ffaker is still about 20x faster than faker.

$ cat scripts/benchmark.rb

# ...
N = 10_000

Benchmark.bm do |rep|
  rep.report("generating #{ N } names") do
    N.times do
      Faker::Name.name
    end
  end
end

• Even though the API is pretty simple, better rdoc documentation would not hurt.

• Put all modules under its respective language (E.G. EducationUS instead of just Education)

• 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.
