Gem Version Build Status

Mummy makes it easy to test yourself for tests and exams. Just like your mum did back when you were younger.


Install the gem (Ruby 2.0.0 and later only):

$ gem install mummy

Then, run mummy with a path to a file to run your test from:

$ mummy GV101/Democracy.txt
$ mummy GV100/ --markdown-heading-level 1

You can write your tests in Markdown (.md) and plain-text (.txt) files. Mummy will detect the right parser to use based on the file type, but you can specify this yourself with a --parser command line argument (e.g. --parser markdown or --parser text).

If you're using a text file, just separate the terms you want to be tested on with line breaks.

If you're using Markdown, prefix the terms to be tested on with ## (i.e. write them as second-level headings). You can change the heading level you want to look for from the default of H2 (##) by specifying a --markdown-heading-level command line option (e.g. --markdown-heading-level 1 will look for lines starting with one "#").

Mummy will read the terms back to you in random order. Hit enter to move onto the next one, or enter an asterisk (*) before hitting enter if you want to run by that term again at the end.


After checking out the repo, run bin/setup to install dependencies. Then, run rake rspec 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


Bug reports and pull requests are welcome on GitHub at This project is intended to be a safe, welcoming space for collaboration, and contributors are expected to adhere to the Contributor Covenant code of conduct.


The gem is available as open source under the terms of the MIT License.


Test yourself on words listed in a file - perfect for revising for exams!
