flutter test -d should give a warning/error #154850
Description
Use case
I often mistakenly run things like flutter test -d chrome1, with the expectation that my test platform will be Chrome. Instead of erroring or telling me what I did wrong, the tests will be executed with the default platform without a problem. I'll admit that this has tricked me into thinking that my tests passed on Chrome before...
Proposal
Instead, if flutter test receives an invalid -d flag, it should output a suggestion to try the --platform flag. I'd also argue that it shouldn't run the tests at all in that scenario.

That's the correct flag for
flutter run, but forflutter testit should be--platform=chrome. ↩
