Serial running

Force test class to run tests in serial.

[TestFixture]
[NonParallelizable]

Internals visible

Make production assembly internals visible through Info.cs file to unit test assemblies:

using System.Runtime.CompilerServices;

[assembly: InternalsVisibleTo("MyProj.UnitTests")]

Asserts

// Assert contains
Assert.That(ex.InnerException.Message, Does.Contain("Issue cannot be empty" ).IgnoreCase);

// Assert property throws exception
Assert.Throws<Exception>(() => { var i = sut.ExistsButIsNotInt; });

// Assert that two IEnumable lists have equal contents
Assert.That(result, Is.EquivalentTo(headerList));

.NET Core proj that uses NUnit

Create new .NET Core project, then:

• Delete any Program.cs
• Remove any output type in .csproj
• Add required references to nuget packages:
  • Microsoft.NET.Test.Sdk
  • NUnit
  • NUnit3TestAdapter

Bare bones test .csproj file example:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.NET.Test.Sdk" Version="16.7.0" />
    <PackageReference Include="NUnit" Version="3.12.0" />
    <PackageReference Include="NUnit3TestAdapter" Version="3.17.0" />
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\..\src\MyProj\MyProj.csproj" />
  </ItemGroup>

</Project>
