🆒 -- although it would also be cool if updating this only required a change in one place!

[zachmargolis]

@jessieay it is only updating in one place? The rest are just specs?

[jessieay]

@zachmargolis I was including specs in my count! I would incline to referencing the constant in specs (in general, I am down with referencing constants in specs rather than magic strings or numbers), but I think we already have this convo and I am cool with keeping as-is.

One way to address @jessieay's point is to move the string to a locale file. That way, the spec tests that the correct locale entry is being called, and changing the entry won't affect the tests, the same way we test most of our strings.

As @jessieay alluded to, I like testing like this because I want to make sure it's the right string. For example if we re-used a constant in the tests and there was a typo with a 4th 'w' in the constant place, then the tests wouldn't catch anything and we'd ship a bug. I think minimal duplication for string-building things like this is totally acceptable 😁
