Testing commands run from view model initializer lists

[ac-zmcnulty]

A few weeks ago, I read up on the Flutter architecture docs, which promote MVVM and use of the command pattern. I've adopted both of those things, as well as command_it along the way (great library, so thank you!!).

I'm a bit confounded when it comes to testing, though.

Again, per the Flutter docs, I've adopted a pattern of running screen loading commands from my view model initializer lists. For example:

class TestViewModel extends ChangeNotifier {
  TestViewModel ({
    required String someProp
  }) : _someProp = someProp {
    load = Command.createAsyncNoResult<LoadCommandArgs>((args) async {
        // ** Command logic ** //
      })..run();
  }

I'd like to test whether the load command runs upon initializing the view model. Is this possible, or should I simply call runAsync on the load command (per the testing docs) and validate it produces the expected results?
