power-assert output fails when using async/await

[jamestalmage]

test.js

import test from 'ava';

function foo() {
    return Promise.resolve(true);
}

test('foo', async t => {
    t.plan(1);
    t.ok(await foo() === false);
});

output

  Error: Line 1: Unexpected identifier
    at Test.<anonymous> (/.../test.js:9:4)
    at step (/.../test.js:5:273)

I have cross-posted here: power-assert-js/babel-plugin-espower#6

I can't tell which library is causing the error. Please close if you are confident it is the power-assert plugin.

@jamestalmage Thank you for reporting.
And yes, this is caused by power-assert (Thank you for cross-posting this).

For now, please avoid using await expression INSIDE assertions.

Doesn't work:

test('foo', async t => {
    t.plan(1);
    t.ok(await foo() === false);
});

Would work:

test('foo', async t => {
    t.plan(1);
    const result = await foo();
    t.ok(result === false);
});

Sorry for inconvenience, I'll fix it ASAP.

Closing since the issue is in power-assert
