Dotnet: painless NUnit project setup

nunit-cheatsheet.md

We'll create a simple project and set up a test. Use case: adder.

0. Install NUnit Framework (only once per machine)

dotnet new -i NUnit3.DotNetNew.Template

1. Create a new console project

dotnet new console -o MyProject

2. Create a new test project in a desired directory (-n)

dotnet new nunit -n MyProjectTest

3. Go to MyProjectTest/ and add a reference to MyProject

$ cd MyProjectTest/
$ MyTestProject/> dotnet add reference ../MyProject/MyProject.csproj

4. Create Adder.cs in MyProject/

namespace adder {
    public class Adder {
        public int add(int a, int b) {
            return a + b;
        } 
    }
}

5. Create AdderTest.cs in MyProjectTest/

using NUnit.Framework;
using adder;

namespace adderTest {
    public class AdderTest {
        [Test]
        public void addTest() {
            Adder adder = new Adder();
            Assert.AreEqual(5, adder.add(2, 3));
        }
    }
}

6. Run tests

$ MyProjectTest/> dotnet test
