Thank you!

Let's add an additional test that runs the migrator on a feedstock and make sure the pinnings repo is setup properly. Then we should be able to merge!

[baszalmstra]

@beckermr Is there an example for one of the other arch migrators that I could copy?

[beckermr]

Not specifically for an arch migration but there are good examples in tests/test_migrators.py.

[baszalmstra]

I have been trying to come up with a test but Im really struggling to grasp how to construct all the different objects at play. If someone has some time, I would love some help with this!

Happy New Year! 🥳

Maybe this would be a good item to discuss at the next bot meeting?

[h-vetinari]

AFAIU we need to wait for conda/conda#14401 (and its equivalent for conda-build) to land first

[wolfv]

Yes, if someone can help us with the appropriate test (or skeleton of tests) that would be highly appreciated.

[beckermr]

This file has a start of an example of how to test: https://github.com/baszalmstra/cf-scripts/blob/win-arm64-migrator/tests/test_flang.py

You'll likely need to add tests of any .bat files you edit as well.

[beckermr]

Two items otherwise Lgtm.

[beckermr]

Merge when you all are ready!
