I'd make sure to update the docs as well if this change does move forward: https://grafana.com/docs/k6/latest/using-k6/k6-options/reference/

Thank you for the PR 🙇

It seems to me like you are changing way too many tests and I expect there might be some problems with the propagation of the default.

Can you try to rever each of the test changes and see if you can reduce them? I haven't commented in each place.

It also will be nice to get a test case in https://github.com/grafana/k6/blob/master/cmd/config_consolidation_test.go#L146 as that is where consolidation is usually tested as well as defaults.

Do you really need to update all of those tests ?

[alex-kattathra-johnson]

My understanding is that the defaults are set at the cmd level. But, these unit tests are testing the functionality of these respective modules independent of the runtime defaults.
