I think there are several folders in appengine missing, e.g., errorreporting.

@fhinkel I think this issue can be closed.

Hey,
The testing documentation, https://cloud.google.com/functions/docs/bestpractices/testing, is sill using ava, but the code is using mocha.

Very confusing. Please update documentation.
