Methods

AddMethodCallbackAsync<TService>(Mocker, Expression<Func<TService, Task>>, Action, bool)

Replaces the current interface registration with a proxy that runs the supplied callback and returns a completed Task for the specified exact asynchronous method call expression.

Declaration

public static TService AddMethodCallbackAsync<TService>(this Mocker mocker, Expression<Func<TService, Task>> callExpression, Action callback, bool replace = true) where TService : class

Parameters

Type	Name	Description
Mocker	mocker	The current Mocker instance.
Expression<Func<TService, Task>>	callExpression	The exact asynchronous method call expression to intercept. FastMoq matcher markers such as FastArg are supported.
Action	callback	The side effect to execute when the call matches callExpression.
bool	replace	True to replace an existing registration for TService. Defaults to true because the helper intentionally swaps in a proxy-backed registration.

Returns

Type	Description
TService	The proxy-backed instance now registered for TService.

Type Parameters

Name	Description
TService	The interface type to wrap.

AddMethodCallback<TService>(Mocker, Expression<Action<TService>>, Action, bool)
