Feature Request: print number of tests skipped

[juliemr]

It would be nice to know if some test files were skipped because they were not on the correct platform.

This is more or less what the @Skip annotation is for: skipping tests visibly. I think it would mostly just be distracting if all tests whose platforms didn't match produced visible output. Also, it's not really possible to do accurately; we need to load the test file to determine what tests it defines, and it's not possible to load a test that imports dart:io on the browser or dart:html in the VM.

If you want to make sure you're running on all the relevant platforms, #46 will allow you to define which ones get used by default.

I don't know, it seems to me that without a warning, it would be very easy to miss a failure that you introduced but didn't actually run the tests for. I'd be happy with a warning that there were some tests that were skipped, without needing to actually parse the file to get a number.

Sounds like #46 could take care of making sure that a random contributor (or normal contributor who is distracted) doesn't accidentally miss some command line flags.
