Let's add test for this, looks good

[rishabh3112]

Looks good. For testing it, you may add a case in serve's smoketest only.

[snitin315]

I am not sure how to mock CTRL + C for tests here.

[alexander-akait]

Just run process using execa and send SIGINT signal, no need to test CTRL + C, because it can be changed by user

[alexander-akait]

I think it is not good to skip windows test here...

[snitin315]

I will see if I can test it on a windows machine locally.

[alexander-akait]

@snitin315 let's rebase, I think it is finished and please don't ignore windows tests, I will fix it if it will have problems

[evenstensberg]

Could you rebase?
