CorporateEspionage

I couldn't figure out how to use Moq to run assertions on calls on mocked objects, so I made my own mocking system to do that.

Features

Uses System.Reflection.Emit to create types at runtime, that implement arbitrary interfaces (mock objects) and record the parameters of any method call
Inspect the parameters of specific invocations, and run assertions using your favorite unit testing framework
Supports methods with an arbitrary amount of parameters, with arbitrary types, or no parameters at all
Supports method with both void and non-void return types (and returns the default value for the type)
Supports methods that return Task or Task<T> (and return Task.CompletedTask or Task.FromResult(default(T)) respectively)
Separate package offering NUnit constraints to make your job easier
Configure the return values of expected method invocations, by invocation index or by parameter criteria

Support for generic types and methods, and recording the generic type parameters

Instead of manually emitting CIL, use a library that can convert expressions into CIL

CorporateEspionage is meant to be used from within unit tests, so this repository's unit tests are good examples of how to use it.
