## Handling error "Could not find a command named frontend_server.dart.snapshot"

Suppose you have an exercise you've already solved and submitted, and you're coming back to it after a while.
You may encounter this error when you test it:

```sh
$ dart test
...
Could not find a command named "/path/to/frontend_server.dart.snapshot".
```

The [solution][solution] is to delete the `pubspec.lock` file.
Then run the dart command again.
