Faker: Quick “Fake Data” Generation in Ruby

By Peter Cooper / December 3, 2007

I love finding a library that does exactly what it claims to do, and does it in the simplest way possible. Faker by Ben Curtis is a Ruby library, packaged as a Ruby Gem, that generates "fake data" for you, in the form of names, telephone number, e-mail addresses, addresses, and so forth.

For example:

Faker::Name.name  # => "Gwendolyn Wehner"
Faker::Internet.email # => "ava.conn@emmerich.info"
Faker::Internet.free_email # => "angelina.labadie@hotmail.com"
Faker::Internet.user_name # => "mitchel.heaney"

This could be particularly useful for throwing data at any libraries or systems you develop that need to process personal details.

I had trouble installing Faker in the usual way (with gem install faker) as the Ruby Gems server reports that the file could not be found. An easy workaround, for now, is to download the gem manually:

wget http://gems.rubyforge.org/gems/faker-0.2.0.gem
gem install faker

    Cool. I think the 404 thing is a problem with the Rubyforge server... I had trouble installing Rails today too.

    This can be particularly useful for test data, sweet. Thanks!

    Hi Peter,

    I've been having problems with rubyforge all day, so I think the issue is on their side.

    Another alternative is my random_data gem with random dates, times, integers, strings, booleans, addresses, as well as the ability to randomly select from a text file:
