factory_girl is a fixtures replacement with a straightforward definition syntax, support for multiple build strategies (saved instances, unsaved instances, attribute hashes, and stubbed objects), and support for multiple factories for the same class (user, admin_user, and so on), including factory inheritance.
If you want to use factory_girl with Rails, see factory_girl_rails.
You should find the documentation for your version of factory_girl on Rubygems.
Add the following line to Gemfile:
bundle install from your shell.
To install the gem manually from your shell, run:
gem install factory_girl
Caveat: As of ActiveSupport 5.0 and above, Ruby 2.2.2+ is required. Because of Rubygems' dependency resolution when installing gems, you may see an error similar to:
$ gem install factory_girl ERROR: Error installing factory_girl: activesupport requires Ruby version >= 2.2.2.
To bypass this, install a pre-5.0 version of ActiveSupport before installing manually.
Supported Ruby versions
The factory_girl 3.x+ series supports MRI Ruby 1.9. Additionally, factory_girl 3.6+ supports JRuby 126.96.36.199+ while running in 1.9 mode. See GETTING_STARTED for more information on configuring the JRuby environment.
For versions of Ruby prior to 1.9, please use factory_girl 2.x.
