I'm not sure what potential side-effects are for this removal.

Perhaps rather leave this in if you're unsure, since it seems like it wouldn't necessary apply to the use case?

because processConfigs was pulled out of the start method, it no longer has access to the screenWriter variable, especially since that also happens later on.
I may be able to store it in some other variable and then reset it to stderr in the start method when it gets called.

Ah I see, if you can keep the existing behaviour it may be best not to remove something that seems so intentional, especially given this is untested code.

Makes sense. Let me update the PR then.

Also, I'm not really sure how to add a test for this, any guidance would be appreciated. |

Hi, what needs to be done to get this merged? |

Hi @gkatsev, sorry for letting you wait that long. I just had another look through your PR and I must admit I have no idea how to add a test myself without adding some kind of mocking framework. From the code side I think this looks good. Even though it goes against my convictions I would actually be willing to merge this as it is without a test considering it is also a rather small change. Any objections from @guybedford ? |

@lukastaegert also, no worries, stuff happens and things fall through the cracks. |
Fixes #1804
This is the beginning of a PR to fixes #1804 based on some of the work that people did in that thread with minimal changes. Thanks @evocateur and @JimPanic
I think the changes are good but there's one thing that I'm not sure if there are any side-effects for but would love to get this merged in.
