Crispr

TODO: Delete this and the text below, and describe your gem

Welcome to your new gem! In this directory, you’ll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file lib/crispr. To experiment with that code, run bin/console for an interactive prompt.

Installation

TODO: Replace UPDATE_WITH_YOUR_GEM_NAME_IMMEDIATELY_AFTER_RELEASE_TO_RUBYGEMS_ORG with your gem name right after releasing it to RubyGems.org. Please do not do it earlier due to security reasons. Alternatively, replace this section with instructions to install your gem from git if you don’t plan to release to RubyGems.org.

Install the gem and add to the application’s Gemfile by executing:

bundle add UPDATE_WITH_YOUR_GEM_NAME_IMMEDIATELY_AFTER_RELEASE_TO_RUBYGEMS_ORG

If bundler is not being used to manage dependencies, install the gem by executing:

gem install UPDATE_WITH_YOUR_GEM_NAME_IMMEDIATELY_AFTER_RELEASE_TO_RUBYGEMS_ORG

Usage

TODO: Write usage instructions here

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 the created tag, and push the .gem file to rubygems.org.

Crispr

Crispr is a mutation testing tool for Ruby. It introduces small mutations into your code to test whether your existing test suite can detect and fail on them. This helps reveal gaps in your test coverage and improve confidence in your codebase.

Installation

Add this line to your application’s Gemfile:

gem "crispr"

And then execute:

bundle install

Or install it yourself as:

gem install crispr

Usage

Run Crispr against a specific file or directory:

crispr run path/to/your/code.rb

The tool will:

• Parse the code into an AST
• Apply simple mutations
• Re-run your test suite for each mutation
• Report which mutations survived (i.e., were not detected by tests)

Development

After checking out the repo, run:

bin/setup

To run the tests:

rake spec

To install this gem onto your local machine:

bundle exec rake install

To release a new version, update the version number in version.rb, then run:

bundle exec rake release
