Invalid retry command if test fails to load #2521
Description
The test failure log includes a handy command to quickly rerun the failing test. But if the test failed because there's a compile error in the test, that message isn't so useful:
To run this test again: dart test test/other_test.dart -p vm --plain-name 'loading test/other_test.dart'
'loading test/other_test.dart' isn't a real test name, so if you fix the compile error and try to run the command it gives you, no tests are run:
> dart test test/other_test.dart -p vm --plain-name 'loading test/other_test.dart'
Building package executable...
Built test:test.
No tests ran.
No tests match "loading test/other_test.dart".
Ideally, the --plain-name part would just be omitted from that message, if the test failed to compile:
To run this test again: dart test test/other_test.dart -p vm
