Describe the bug
When writing a test that is not inside /test folder, the output of a failing test is "═════..." (take a look at the screenshot)

the debug console displays the correct exception

To Reproduce
flutter create

enter the sample code into the test file integration_test/widget_test.dart

hint: the official flutter tutorial for integration tests also creates it inside /integration_test folder
https://docs.flutter.dev/testing/integration-tests#create-the-integration-test-files

and another hint, because this is a flutter vscode bug I was advised to open the issue here
flutter/flutter#159264

Expected behavior
Displaying the correct exception into the vscode ui

Code Sample

import 'package:flutter/material.dart';
import 'package:flutter_test/flutter_test.dart';

Future<void> main() async {
  group(
    "integration test",
    () {
      testWidgets("test1", (WidgetTester tester) async {
        await tester.tap(find.byKey(Key("NotExistingKey")));
      });
    },
  );
}
