Mimic

Fast, friendly and familiar mocking library for modern .NET

What is Mimic | Features | Roadmap | Changelog

---

Mimic is still very early in it's development and the functionality and/or interfaces that it provides are subject to change without warning between versions until the v1 release.

What is Mimic

Mimic is a friendly and familiar mocking library built for modern .NET built on top of the Castle Project's dynamic proxy generator. It's simple, intuitive and type-safe API for configuring mimic's of interfaces/classes allows for both; Setup of return values for methods/properties and verifying if method calls have been received after the fact.

var mimic = new Mimic<ITypeToMimic>(); // Easily setup methods mimic.Setup(m => m.IsMimicEasyToUse(Arg.Any<string>())) .Returns(true); // Access the `Object` property to generate an implementation of `ITypeToMimic` and call our setup method ITypeToMimic mimickedObject = mimic.Object; bool whatDoYouThink = mimickedObject.IsMimicEasyToUse("it's so intuitive"); // Verify that the specified method has been called at least once on the `Object` mimic.VerifyReceived(m => m.IsMimicEasyToUse("it's so intuitive"), CallCount.AtLeastOnce);

Features

• A friendly interface designed to ease adoption by users of other popular .NET mocking libraries
• Support for generating mock objects of interfaces and overridable members in classes
• Intuitive and type-safe expression based API for setups and verification of methods
• Mimic is strict by default, meaning it throws for methods without a corresponding setup, but it's possible to disable the default behaviour by setting Strict = false on construction
• Quick and easy stubbing of properties to store and retrieve values
• Implicit mocking of interfaces returned by mimicked methods allowing for easy setup of nested calls
• Comprehensive set of behaviours for method setups such as; Returns, Throws, Callback, When, Limit, Expected, AsSequence and Proceed
• Verification of expected, setup and received calls including asserting no additional calls

Roadmap

Considering = ❓ | Planned = 📅 | In-Progress = 🚧

• [❓] Setup and Verification of Event's
• [❓] Configurable default return values instead of just null for reference and default for value types when Strict = false
