Moq is a mocking library for .NET that takes advantage of .NET 3.5 and C# 3.0 features to be the most productive and refactoring-friendly mocking library available. Mocking libraries allow developers to mock or fake dependencies for classes to enable isolated unit testing. Moq is used to mock objects that are non-deterministic, difficult to initialize, don't yet exist, or would include unnecessary test code. Moq allows creating mock instances, setting expectations on mocks, and using mocks in tests. The document provides an example of mocking HttpContext and includes references for more information on Moq.

WHAT
• Moq (pronounced "Mock-you" or just "Mock") is the only mocking library
for .NET developed from scratch to take full advantage of .NET 3.5 (i.e. Linq
expression trees) and C# 3.0 features (i.e. lambda expressions) that make it
the most productive, type-safe and refactoring-friendly mocking library
available.

WHY
• the object supplies non-deterministic results (e.g., the current time or the
current temperature);
• has states that are not easy to create or reproduce (e.g., a network error);
• is slow (e.g., a complete database, which would have to be initialized
before the test);
• does not yet exist or may change behavior;
• would have to include information and methods exclusively for testing
purposes (and not for its actual task).
