In the comments, I threw out the term "Mitali Test," which other commenters seemed to like. (I also demonstrated my inability to spell "knew," but that's another story.)
The Mitali Test asks three questions about a book:
- Are there two or more people of color with names?
- Do they have a significant conversation with each other?
- Do they talk about something other than race?
I decided to apply the Mitali Test to the middle-grade and YA books in my LibraryThing collection. Here's what passed*:

Is this a comprehensive list? Hardly. But it's a start.
*I was relying on memory when I compiled this list, and it's been a while since I read a few of these. Feel free to correct me on any that don't meet all three criteria.
