@manekinekko Please review some of the tests that I have added in https://github.com/Azure/static-web-apps-cli/tree/ga/src/core/utils/options.spec.ts file as per your convenience so that I know if I'm doing it correctly or not 😅

[manekinekko]

You are in the right direction 👍

@manekinekko @sinedied I have finished adding alias flags for all of the commands that have been created so far along with their corresponding Unit tests. Please review the alias flags for the command options and do let me know if they need to be updated accordingly.

P.S:- I haven't added alias flags for a few short options like --env, --auto since I thought that it might not be needed as they are short (Do let me know, if needed, I can add them).

@manekinekko I have rebased and added alias flags for some of the new options that were added on the ga branch. Also updated README.md with these new alias flags for existing commands (I haven't added the alias flags for commands like login since it hasn't been added to docs yet 😅).

[sinedied]

I've made some tiny changes as it seems some recent flags changes were lost in your rebase, thanks for your PR!
