.NET library to mock object properties with attributes

Tagger.Reflect

.NET library to mock object properties with attributes.

What is for?

I initially designed this library for writing tests for Command Line Parser Library. Although it's main purpose is testing, it can be helpful in the scope of dynamic programming.

Targets

• .NET Standard 2.0
• .NET Framework 4.6.1

Install via NuGet

$ dotnet add package Tagger.Reflect --version 1.6.9-beta

The latest stable version is 1.0.3.

At a glance

interface IMyInterface
{
    string Foo { get; set; }
    int Bar { get; set; }
    bool Baz { get; set; }
}

// define an anonymous template limited to target properties
var mirror = new Mirror(new { Foo = default(string) })
    .Implement<IMyInterface>()
    .Add(x => x.ForProperty("Foo")
               .Define<MyAttribute>()
               .AttributeCtor(new { index = 0 })
               // define an anonymous instance for each attribute
               // property to set
               .AttributeProperty(new { Dir = "/etc/app" })
               .AttributeProperty(new { Config = "file.dat" });

var instance = mirror.Unwrap<IMyInterface>();

// instance layout:
// class anonymous : IMyInterface {
//     ...
//     [MyAttribute(0, Dir = "/etc/app", Config = "file.dat")]
//     public string Foo { get; set; } 
//     ...
// }

See this unit test for more examples.
