dart: imports are before package: imports (iirc).

Done, and changed for the other tests in this folder.

 
 main() {
-  var result = Process.runSync(Platform.executable,
-      [Platform.script.resolve('./bad_snapshot').toFilePath()]);
-  print("=== stdout ===\n ${result.stdout}");
-  print("=== stderr ===\n ${result.stderr}");
-  Expect.equals(253, result.exitCode);
+  // Even though we are only calling toString() we should still have an
+  // interceptor for ByteData so that it doesn't end up as an unknown JS object.
+  // This test is just to make sure we don't crash.
+  new ByteData(1).toString();

You need to do something with the string as otherwise it might just get removed
entirely in the output.

Who is "we" ?
The "interceptor" part doesn't make sense for the VM. Mention "dart2js".

Done.
