Hey hey, @DominikKamp, glad to see you here 😄

We had some problems with printing and people having weird locales (#830, #843). Do you think we might need to be concerned with this here as well?

Also, can you please add some tests?

Do you think we might need to be concerned with this here as well?

The function relayMessage() already gets an assembled string so that the locale should not matter here.

Also, can you please add some tests?

I do not really know, how the console output could be tested. But it could be tested that writeProblem() still creates a non-empty file after redirectOutput(). Where do unit tests go?

Yeah, the output itself should be hard to test, but just that it's being printed to the correct place.

We have a bunch of test_XX.py files, so it's mostly a matter of seeing in which it makes more sense, defaulting to test_model.py. I think it makes sense to add it here. There's also the possibility of creating a new test file, if you think it is justified (it also needs to be prefixed by test_).

The test function needs to be prefixed by test_, and you can use some models we have stored in helpers/utils.py, in case you don't want to build a new one.

Tests added but please verify that the console output is still as expected with and without redirectOutput().

Before doing anything else, it seems like the mac pipeline has to be fixed because the github runner is not able to compile the SCIPOptSuite before eternity ends (why not use the precompiled version like in the Windows-test?).

Changes look good. I will test before merging.

This does fix the issue on writeProblem. It also seems to help with #896

Let's wait until #933 is merged as then the pipelines can run faster
