I know that Karl prefers to use just "client" API
but I usually initialize CUT "with the shortcut", not whole (sometimes
complex) flow used by "client" API.
Using whole flow makes test method longer, more brittle, harder to
understand (and test runs slower).
If "shortcut" method is dangerous (can make problems/inconsistence
when real client code will use it) -
name can start with Testing, /* like Michael Feathers' stuff with
setting testing instance for Singleton */
method can be internal (and assembly has InternalVisibleTo attribute)
and used just in debug mode
So I would have the test like this:
[Test]
public void
ChangeRole_DeselectRoleRequestIsPending_DoesNotSendDeselectRoleCadRequest()
{
// Arrange
InitializeObjectUnderTest();
// something like this
_logic.TestingSetStateToDeselectRoleRequestPending();
// Act
_logic.ChangeRole();
// Assert
DispServerConnection.AssertWasNotCalled(x =>
x.SendDeselectRoleCadRequest());
}
QST: guys, do you prefer to use just "client" API ???
