What mistakes I made in this practice:

Misunderstanding the requirement.
Do validation first.
Detail first rather than simple first.

Initial Setup

dotnet new classlib -n Kata
dotnet new xunit -n Kata.Tests
dotnet new sln
dotnet sln add Kata Kata.Tests
cd Kata.Tests
dotnet add reference ../Kata
dotnet add package FluentAssertions NSubstitute
cd ..

The following command should run all tests:

dotnet test
