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.
- 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!
Please complete each story in order.
As a donor
I want to see my gift aid calculated according to the current tax rate
So that I know how much extra cash the charity will make
- Gift aid calculated at a tax rate of 20%.
- Supported by unit tests.
As a site administrator
I want to be able to change the applicable tax rate
So that I don't need to change the code when the tax rate changes
- Current Tax Rate is retrieved from data store.
- Gift Aid amount is calculated based on the current amount in the data store.
As a donor
I want to see my gift aid amount rounded correctly to 2 decimal places
So that I'm not confused about how much will be paid to the charity
- Gift aid amount correctly rounded to 2 decimal places (1.316 should round to 1.32).
As an events promoter
I want to supplement gift aid payments based on event type
So that people will feel inspired to donate to these event types
- 5% supplement added for donations to "running" events.
- 3% supplement added for donations to "swimming" events.
- No supplement should be applied for other events.
Thanks for your time, we look forward to hearing from you!
