Is anyone interesting in picking this up? Otherwise I'll assign it to myself in about an hour.

I imagine we can mostly duplicate the existing String.prototype.replace tests, modifying those tests where searchValue and replaceValue are both strings. At that point, we’d only have to add tests for the exception on a non-global RegExp searchValue (but again, we can mostly re-use the existing matchAll tests for that).

Sure thing, I'm just checking as IIRC, @ljharb has expressed intention to write these tests in the last meeting. Otherwise, I'm gonna get this covered this week. (today or tomorrow, optimistically).

Feel free to do it before i find time to :-)

This would be amazing if we didn't have too many legacy tests.
