MustBeCalled partial argument match

[Edoardo]

Another question on MustBeCalled. Is there a way to assert a partial match of an argument?

For example, the first argument of the call to be asserted is an object which has 10 properties but I only care about 2 of them in the particular test case.

Thanks!

A failed attempt/example:

var accounts = ...
var target = Mock.Create<TargetClass>(Behavior.CallOriginal, accounts);

Mock.Arrange(() => target.TestCall(Arg.IsAny<Account>()).DoNothing();

target.Run(); // Will call internal TestCall for each account

foreach(var account in accounts)
Mock.Assert(() => target.TestCall(Arg.Matches<Account>(x => x.FirstName == account.FirstName && x.LastName == account.LastName), Occurs.Once());

Error is: Expected TargetClass.TestCall(Accoutn) call on the mock should be once, but it was called 0 times(s).

Any suggestion, please?

Hi Edoardo,

Thanks again for contacting us.

However, Mock.Assert will fail right away when something that is expected but not executed. Therefore, in your case asserting specific criteria in a loop won't work as the moment it will hit with the wrong expectation the test will fail.
