Most of the tests are working now. The ones that don’t are those that send GraphQL queries to a running server. Something bizarre has happened with how Mocha and/or Chai expects callbacks to be handled, possibly to do with done functions. Of course, both of them have radically different APIs now from when we first started using them.

I now have mod-graphql working just fine under Node without Babel.

The bad news: the tests won’t run due to some confusion about import vs. require, and it’s hard to get to the bottom of what’s causing the problem due to all the inversion of control in the testing framework (Mocha). I’ll get there.
