Summary: ## Changes in this pull request It's been a few years since I did an audit of our test suite. The majority of changes to IGListKit since then were adding additional error checking and hardening, so this was relatively straightforward. ### Checklist - [x] All tests pass. Demo project builds and runs. - [x] I added tests, an experiment, or detailed why my change isn't tested. - [x] I have reviewed the [contributing guide](https://github.com/Instagram/IGListKit/blob/main/.github/CONTRIBUTING.md) Pull Request resolved: https://github.com/instagram/IGListKit/pull/1654 Reviewed By: jurmarcus Differential Revision: D91551666 Pulled By: TimOliver fbshipit-source-id: c89c7a45abebb44dbf50b252bfadc9a7c2928683
