Nice that you want to learn Test-Driven Development (TDD)! Here you find a simple app that can help you calculate the amount of your bill when you want to add a tip! It (should) calculate the amount when there is a tip added and the total amount when taxes are applied too.
The project contains a View with properties (constant values), and it is your task with TDD to implement a View Model that helps the view calculate the Bill Amount + Tip and the Total Amount (Bill Amount + Tip + Taxes/VAT).
Clone this project, and check out the start branch - this is where you will start working.
git clone <correct url/ssh path>
git checkout startUse TDD methodology when solving the task. Remember: Write the test, let it fail, write the code that needs to pass the test and repeat, see image below.
