15+
## Notes
16+
* You can check app-automate Espresso related endpoints on [BrowserStack app-automate Espresso](https://www.browserstack.com/app-automate/espresso/get-started)
17+
* You can view your test results on the [BrowserStack app-automate dashboard](https://www.browserstack.com/app-automate)
18+
19+
## Additional Resources
