Rocks

A mocking library based on the Compiler APIs (Roslyn + Mocks)

Getting Started

Reference the Rocks NuGet package - that's it.

Prerequisites

The Rocks package targets .NET Standard 2.0 for host flexibility. That said, Rocks (as of 9.0.0) will generate code that requires .NET 9.

Usage

To make a mock, you take an interface or an unsealed class that has virtual members:

public interface IAmSimple
{
  void TargetAction();
}

and you use Rocks to create a mock with expectations, along with verifying its usage:

[assembly: Rock(typeof(IAmSimple), BuildType.Create)]

var expectations = new IAmSimpleCreateExpectations();
expectations.Methods.TargetAction();

var mock = expectations.Instance();
mock.TargetAction();

expectations.Verify();

More details can be found on the Overview page.
