Intro

A big part of what we do at JustGiving is reclaim the Gift Aid on donations made to charities. This saves them a lot of time and processing overheads.

This assignment is a very small task to create a Gift Aid calculator.

For reference, Gift Aid is calculated as follows:

[Donation Amount] * ( [TaxRate] / (100 - [TaxRate]) )

  • This assignment takes an average of about 30 minutes.
  • We use NUnit and Moq at JustGiving, references have been added using NuGet Packages. Everything is in place for you to just write the code (no "File > New Project" required).
  • Please DO NOT fork this project on Github, as we want to be sure candidates' test submissions are original.

Task requirements

  • All stories to be completed with an appropriate level of testing.
  • No actual database implementation is required, feel free to stub it out.
  • Your code should trend towards being SOLID.
  • Please download the Recruitment-Test repository, complete the tasks as you see fit.
  • Send us a Dropbox/Skydrive/whatever link to your zipped code to james.adams@justgiving.com but please do not send attached zip files via email!
