This preserves the shape of the previous API, but stubs out the functionality.
This is a temporary measure designed to make it easier for users to try the

This ensures that console_reporter_test isn't run on browsers, and
improves the path detection for test/io.dart.

This is still extremely bare-bones and won't work with tests that actually

Remove the "build/" prefix from a bunch of status lines, add a missing

This also adds LiveTest.close, which releases resources associated with a
LiveTest.
