Is your feature request related to a problem?

Hi! I'm trying to implement "Run tests" button. I've created button according to guide at https://tutorialkit.dev/guides/how-to-use-tutorialkit-api/#write-to-terminal

However, there are 2 problems:

1. I need to create extra terminal for "npm run test" command, because the first terminal is already open for the dev server. Is it correct?
2. It seems that I don't have access to "npm run test" result. I want to display a message to the user after the test pass. How can I do this?
