Ensure that t.throwsAsync() and t.notThrowsAsync() are awaited

When you use the t.throwsAsync() and t.notThrowsAsync() assertions, you must await the promise they return. If the test function completes before the assertions do, the test will fail.

This rule is fixable inside async functions. It will insert await before t.throwsAsync() and t.notThrowsAsync().

Fail

import test from 'ava';

test('main', t => {
	t.throwsAsync(somePromise);
	t.notThrowsAsync(somePromise);
});

Pass

import test from 'ava';

test('main', t => {
	await t.throwsAsync(somePromise);
	await t.notThrowsAsync(somePromise);
	const p = t.throwsAsync(somePromise);
	t.throwsAsync(somePromise).then(…);
});
