I included what I thought would be useful, but could use some feedback on it.

Anything missing or something that could be improved? (Assertion snippets are planned https://github.com/sindresorhus/atom-sublime/issues/1).
Sublime has pretty powerful snippet system http://docs.sublimetext.info/en/latest/extensibility/snippets.html#substitutions, so I was thinking we could for example in the AVA snippet autofill the import by converting camelCase fooBar to foo-bar with a regex, e.g. import fooBar from 'foo-bar', so foo-bar is autofilled in this case.
