To get started, make sure you have VirtualBox
and Vagrant installed. Then, clone this
repository, cd to the folder, and run vagrant up.
Once that's done, vagrant ssh, cd to /vagrant and run
ruby calculator_test.rb. You should see output that looks like this:
# Running tests:
Finished tests in 0.000756s, 0.0000 tests/s, 0.0000 assertions/s.
0 tests, 0 assertions, 0 failures, 0 errors, 0 skips
If that's what you got, you're good to go!
The exercise is called "String Calculator" and is based off of the information found here.
All of the steps can be found in requirements.md. Typically you would take one, write the test, write code that passes the test, refactor, and then move on to the next one.
The vagrant box is setup for ruby development, but of course the requirements are not language specific and therefore can be done in any language.
The presentation PDF is located at presentation.pdf, or on SpeakerDeck. PDFs are not very friendly to GIFs, so it does look a little weird. It was written in Markdown and presented using Deckset. The original Markdown file can be found in presentation.md.
