Analyzer

FakeItEasy provides a Roslyn analyzer to detect incorrect usages of the library that cannot be prevented by the API or the compiler but will typically result in bugs at runtime.

Installation

The analyzer works in Visual Studio 2015 Update 1 or later. It can be installed from NuGet for each project that needs it:

PM> Install-Package FakeItEasy.Analyzer

Diagnostics

The analyzer currently provides two diagnostics:

Id Summary Description
FakeItEasy0001 Unused call specification Triggered when you specify a call but don't configure or assert it, making it a no-op.
FakeItEasy0002 Non-virtual member configuration Triggered when you try to configure a non-virtual member, which cannot be faked.
FakeItEasy0003 Argument constraint outside call spec Triggered when you try to use an argument constraint outside of a call specification.
