A friendly substitute for .NET mocking libraries.

NSubstitute is designed as a friendly substitute for .NET mocking libraries. It is an attempt to satisfy our craving for a mocking library with a succinct syntax that helps us keep the focus on the intention of our tests, rather than on the configuration of our test doubles. We've tried to make the most frequently required operations obvious and easy to use, keeping less usual scenarios discoverable and accessible, and all the while maintaining as much natural language as possible. Perfect for those new to testing, and for others who would just like to to get their tests written with less noise and fewer lambdas. 

A .NET dynamic fake library for creating all types of fake objects, mocks, stubs etc. Easier semantics, all fake objects are just that - fakes - the use of the fakes determines whether they're mocks or stubs. Context-aware fluent interface guides the developer. Designed for ease of use. Full compatibility with both C# and VB.Net. 

WireMock.Net is a flexible library for stubbing and mocking web HTTP responses using advanced request matching and response templating. Based on the functionality from http://WireMock.org, but extended with more functionality.

A C# .NET version based on mock4net which mimics the functionality from the JAVA based WireMock.org. For more info, see also this WIKI page: What is WireMock.Net. HTTP response stubbing, matchable on URL/Path, headers, cookies and body content patterns Library can be used in unit tests and integration tests Runs as a standalone process, as windows service, as Azure/IIS or as docker Configurable via a fluent DotNet API, JSON files and JSON over HTTP Record/playback of stubs (proxying) Per-request conditional proxying Stateful behaviour simulation Response templating / transformation using Handlebars and extensions Can be used locally or in CI/CD scenarios

Moking Entity Framework Core operations such ToListAsync, FirstOrDefaultAsync etc

Extensions for mocking Entity Framework Core (EFCore) operations such ToListAsync, FirstOrDefaultAsync etc. by Moq, NSubstitute or FakeItEasy When writing tests for your application it is often desirable to avoid hitting the database. The extensions allow you to achieve this by creating a context – with behavior defined by your tests – that makes use of in-memory data. 

Spikes resulted in :. Both make the foundation of Moq v5. https://github.com/kzu/avatar https://github.com/moq/moq 

An automocking container for Moq. Use this if you're invested in your IoC container and want to decouple your unit tests from changes to their constructor arguments. 

AutoMoqer is an "auto-mocking" container that creates objects for you. Just tell it what class to create and it will create it.
