RSCG – mocklis
 
 

Generating mocks from classes for unit tests

This is how you can use mocklis .

The code that you start with is

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

  <PropertyGroup>
    <TargetFramework>net8.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>

    <IsPackable>false</IsPackable>
    <IsTestProject>true</IsTestProject>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.NET.Test.Sdk" Version="17.9.0-preview-23577-04" />
    <PackageReference Include="Mocklis" Version="1.4.0-alpha.2" />
    <PackageReference Include="MSTest.TestAdapter" Version="3.2.0-preview.23623.1" />
    <PackageReference Include="MSTest.TestFramework" Version="3.2.0-preview.23623.1" />
    <PackageReference Include="coverlet.collector" Version="6.0.0">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    </PackageReference>
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\MockLisClock\MockLisClock.csproj" />
  </ItemGroup>
	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>

</Project>

The code that you will use is

namespace TestClock;

[MocklisClass]
public partial class TestMock : IMyClock
{

}

using Mocklis;

namespace TestClock;

[TestClass]
public class TestClock
{
    [TestMethod]
    public void TestMyClock()
    {
        var mockSetup = new TestMock();
        mockSetup.GetNow.Return(DateTime.Now.AddYears(-1));

        // When testing the mock like this you need to cast to the interface.
        // This is different from e.g. Moq where the mocked instance and the 'programming interface' are different things.
        // With Mocklis they are the same. The 99% case is where the mock is passed to another constructor as a dependency,
        // in which case there's an implicit cast to the interface.
        var mock = (IMyClock)mockSetup;
        var data = mock.GetNow();
        Assert.AreEqual(DateTime.Now.Year - 1, data.Year);

    }
}

global using Microsoft.VisualStudio.TestTools.UnitTesting;
global using MockTest;
global using Mocklis.Core;

The code that is generated is

// <auto-generated />

namespace TestClock
{
    partial class TestMock
    {
        public global::Mocklis.Core.FuncMethodMock<global::System.DateTime> GetNow { get; }

RSCG – RSCG_UtilityTypes
 
 

Add omit and pick to selectively generate types from existing types

This is how you can use RSCG_UtilityTypes .

The code that you start with is

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

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net8.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>
  <ItemGroup>
	  <PackageReference Include="RSCG_UtilityTypes" Version="2023.1223.1230" OutputItemType="Analyzer" ReferenceOutputAssembly="false" />
	  <PackageReference Include="RSCG_UtilityTypesCommon" Version="2023.1223.1230" />
  </ItemGroup>
	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>
</Project>

The code that you will use is

using UtilDemo;

var p=new PersonFull();
p.FirstName="Andrei";
p.LastName="Ignat";
Person1 p1=(Person1)p ;
Person2 p2=(Person2)p ;
Console.WriteLine(p1.FirstName);
Console.WriteLine(p2.LastName);

using RSCG_UtilityTypesCommon;

namespace UtilDemo;
[Pick("Person1",nameof(FirstName),nameof(LastName))]
[Omit("Person2", nameof(Salary))]
public class PersonFull
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public int Salary { get; set; }

}

The code that is generated is

namespace UtilDemo
{
partial class Person1
    {
        public string FirstName { get; set; }
        public string LastName { get; set; }

public static explicit operator Person1(PersonFull data )
    {
        var ret= new Person1 ();
        ret.FirstName = data.FirstName;
ret.LastName = data.LastName;
        return ret;
    }



public static explicit operator PersonFull(Person1 data )
    {
        var ret= new PersonFull ();
        ret.FirstName = data.FirstName;
ret.LastName = data.LastName;
        return ret;
    }


}
}

namespace UtilDemo
{
partial class Person2
    {
        public string FirstName { get; set; }
        public string LastName { get; set; }

public static explicit operator Person2(PersonFull data )
    {
        var ret= new Person2 ();
        ret.FirstName = data.FirstName;
ret.LastName = data.LastName;
        return ret;
    }



public static explicit operator PersonFull(Person2 data )
    {
        var ret= new PersonFull ();
        ret.FirstName = data.FirstName;
ret.LastName = data.LastName;
        return ret;
    }


}

RSCG – Ling.Audit
 
 

Generating audit data from class implementation of interfaces

This is how you can use Ling.Audit .

The code that you start with is

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

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net8.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>

  <ItemGroup>
    <PackageReference Include="Ling.Audit" Version="1.1.0" />
  </ItemGroup>
	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>
</Project>

The code that you will use is

// See https://aka.ms/new-console-template for more information
using LingDemo;

Console.WriteLine("Hello, World!");
var p = new Person();
await Task.Delay(2000);
p.FirstName = "Andrei";
p.LastName = "Ignat";
Console.WriteLine(p.CreationTime);
Console.WriteLine(p.LastModificationTime);

using Ling.Audit;

namespace LingDemo;
partial class Person :IFullAudited<Guid>
{
    public int ID { get; set; }
    public string FirstName { get; set; }= string.Empty;
    public string LastName { get; set; } = string.Empty;
}
