[antongolub]

closes #1116

const cwd = tmpdir()
const external = tmpdir()
await fs.outputJson(path.join(external, 'node_modules/a/package.json'), {
  name: 'a',
  version: '1.0.0',
  type: 'module',
  exports: './index.js',
})
await fs.outputFile(
  path.join(external, 'node_modules/a/index.js'),
  `
export const a = 'AAA'
`
)
const script = `
import {a} from 'a'
console.log(a);
`
const out =
  await $`node build/cli.js --cwd=${cwd} --prefer-local=${external} --test <<< ${script}`
assert.equal(out.stdout, 'AAA\n')
