Bundler::Fixture

A simple fixture to generate a for-realz Gemfile.lock with completely fake data.

Bundler has wonderful fixture tooling for testing itself, but it's pretty elaborate and hard (for a knucklehead like me) to re-use. I cobbled this together and wanted to re-use it elsewhere and decided to package it up separately.

Works with Bundler 1.7+

Installation

Add this line to your application's Gemfile:

gem 'bundler-fixture'

And then execute:

$ bundle

Or install it yourself as:

$ gem install bundler-fixture

Usage

require 'bundler/fixture'

bf = BundlerFixture.new(dir: Dir.tmpdir)
bf.create_lockfile(gem_dependencies: bf.create_dependency('foo', '1.4.5'))

BundlerFixture takes the gem specs and builds an index with the contents, and sets up other dependencies so a Gemfile.lock can be built reflecting the dependency tree in all of the passed specs with Bundler::Definition. This ensures Bundler::LockfileParser will be able to parse the file successfully, handy for testing your own code that's working programatically with its output.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
