[wix-users] Unit Test Deferred Custom Actions

[Nir Bar]

Since you already factored-out the execution logic from the Session parsing logic you can simply create a local Log() function that will dump log messages to Session.Log() or Console.WriteLine() as appropriate.

One thing to note however, is that unit-testing custom actions can't be complete without executing it in LocalSystem account (as opposed to an Administrator account).

I usually unit-test custom actions by developing a standalone package that only executes the custom action. 
I suppress PublishXXX and RegisterXXX standard actions so the package just executes the custom actions without leaving any other trace on the machine.
