Regression Notes

1. Potential unintended areas of impact

2. What I did to test those areas of impact (or what existing automated tests I relied on)

3. What automated tests I added (or what prevented me from doing so)

PR submission checklist:

• I have completed the Regression Notes.
• I have considered adding unit tests for my changes.
• I have considered adding accessibility improvements for my changes.
• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.

Testing checklist:

• WordPress.com sites and self-hosted Jetpack sites.
• Portrait and landscape orientations.
• Light and dark modes.
• Fonts: Larger, smaller and bold text.
• High contrast.
• VoiceOver.
• Languages with large words or with letters/accents not frequently used in English.
• Right-to-left languages. (Even if translation isn’t complete, formatting should still respect the right-to-left layout)
• iPhone and iPad.
• Multi-tasking: Split view and Slide over. (iPad)

Alright!

Sorry it took me a while to review this, but I wanted to verify it locally (just in case!) using the steps from #24247

All good!

Approving to unblock, my question regarding the scope to which we should wrap possible exceptions is not a blocker at all.

[mokagio]

I suppose we consider safe to blanket ignore any exception here because we are confident they would arise only when running unit tests due to the many stateful assumption in the app at the moment.

Is that safe?

How would you feel about running this only if NSClassFromString("XCTestCase") != nil?
