@jywarren please have a look😁

Awesome! Do you think it would be tough to add a test for this? I guess we don't have CLI tests... what do you think?

[tech4GT]

@jywarren Not at all. Adding a test for this right away😁

[tech4GT]

@jywarren should i create a separate issue for adding cli tests so we can add tests for other stuff like validate steps as well, what say?

[tech4GT]

@jywarren actually for creating this output directory all we have done is just call a native nodejs file system function so for adding a test for this i would have to wrap this up in a function but since it is only one line it will introduce unnecessary complexity, should i do it?

[jywarren]

Actually i think making a createDirectory function independently is probably a good idea, no? Clearly marked as running on the CLI/node only? What do you think?

[tech4GT]

@jywarren it's done please have a look, also i found a small error that if we do not give any steps to cli it does not exit cleanly, so i also fixed that in this commit. Thanks
