Utility factory class to use to construct multiple
mocks when consistent verification is
desired for all of them.

Remarks
If multiple mocks will be created during a test, passing
the desired MockBehavior (if different than the
Default or the one
passed to the factory constructor) and later verifying each
mock can become repetitive and tedious.
This factory class helps in that scenario by providing a simplified creation of multiple mocks with a default MockBehavior (unless overriden by calling Create<(Of <<'(T>)>>)(MockBehavior)) and posterior verification.
Examples
The following is a straightforward example on how to
create and automatically verify strict mocks using a MockFactory:
The following examples shows how to setup the factory
to create loose mocks and later verify only verifiable setups:
The following examples shows how to setup the factory with a
default strict behavior, overriding that default for a
specific mock:
CopyC#
var factory = new MockFactory(MockBehavior.Strict); var foo = factory.Create<IFoo>(); var bar = factory.Create<IBar>(); // no need to call Verifiable() on the setup // as we'll be validating all of them anyway. foo.Setup(f => f.Do()); bar.Setup(b => b.Redo()); // exercise the mocks here factory.VerifyAll(); // At this point all setups are already checked // and an optional MockException might be thrown. // Note also that because the mocks are strict, any invocation // that doesn't have a matching setup will also throw a MockException.
CopyC#
var factory = new MockFactory(MockBehavior.Loose); var foo = factory.Create<IFoo>(); var bar = factory.Create<IBar>(); // this setup will be verified when we verify the factory foo.Setup(f => f.Do()).Verifiable(); // this setup will NOT be verified foo.Setup(f => f.Calculate()); // this setup will be verified when we verify the factory bar.Setup(b => b.Redo()).Verifiable(); // exercise the mocks here // note that because the mocks are Loose, members // called in the interfaces for which no matching // setups exist will NOT throw exceptions, // and will rather return default values. factory.Verify(); // At this point verifiable setups are already checked // and an optional MockException might be thrown.
CopyC#
var factory = new MockFactory(MockBehavior.Strict); // this particular one we want loose var foo = factory.Create<IFoo>(MockBehavior.Loose); var bar = factory.Create<IBar>(); // specify setups // exercise the mocks here factory.Verify();
