 To keep the browser open after a spec run (for easier debugging and iterating on specs), you can pass the `--no-exit` flag to the e2e test command. Live reloading due to spec changes should also work:
 ```sh
-yarn test test/e2e/2_go_spec.js --browser chrome --no-exit
+yarn test test/e2e/go_spec.js --browser chrome --no-exit
 ```
