Questions tagged [nsubstitute]

NSubstitute is a .NET mocking framework. It creates substitutes of types for testing that can act as both mocks (can check calls were received) and stubs (can configure results for calls).

NSubstitute is a dynamic .NET mocking library, compatible with netstandard-1.3 and .NET 4.5 and above (earlier versions support back to .NET 3.5).

Using a "fluent" syntax, it creates substitutes of types for testing that can be configured to return specific results for calls, or can be queried about the calls they did receive. As this combines the behaviour of "mocks" and "stubs", NSubstitute uses the term "substitute" to describe these test doubles.
