Hi got this error

  √ should load from memory
TypeError: Cannot read property 'stats' of undefined

Here's my code

import test from 'ava';
import { rollup } from 'rollup';

process.chdir(__dirname);

test('should load from memory', t => {
    return rollup({
        entry: '../src/index.js',
        plugins: []
    }).then(bundle => {
        var result = bundle.generate({
            format: 'cjs'
        });

        console.log(result.code);
    });
});

When I remove console.log, error does not reject. It doesn't seem problem in rollup.

Thanks for report. We'll look into it.

process.chdir(__dirname);

You don't need this. AVA does this for you.

And btw, you should take advantage of async functions ;)

import test from 'ava';
import { rollup } from 'rollup';

test('should load from memory', async t => {
    const bundle = await rollup({
        entry: '../src/index.js',
        plugins: []
    });

    const result = bundle.generate({
        format: 'cjs'
    });

    console.log(result.code);
});

@sindresorhus Oh cool about chdir. I'm just afraid a little new syntax :)) But will try. Still babel is out of the box :)

I got this error too.
In my case, I saw that it was caused by padding ava an empty .js file.

I was able to recreate from scratch by running ava via cli on a directory containing one file with a valid test and another empty file.
