Babel plugin for protecting against improper use of t.throws() in AVA
Probably not useful except as an internal plugin for the AVA test runner.
Genesis of the idea.
Issue
I've seen a lot of incorrect use of the throws assertion in other test runner and even done the mistake myself sometimes. Now I'm beginning to see it with AVA too, so would be nice to be preemptive about it.
People don't realize they need to wrap their call in a function, so many end up doing t.throws(foo()) instead of t.throws(() => foo());. It's an easy mistake to make.
The difficulty is that t.throws(foo()) is allowed if foo() returns a promise or a function. There is no good way to differentiate between the two at runtime. So providing a good error message is going to take some AST transform magic.
Solution
See test.js.md for the transformation this plugin performs.
