$policy = ExecutionPolicy::in(__DIR__);
// @doctest id="4f58"

​

$policy = $policy
    ->withTimeout(30)
    ->withIdleTimeout(10)
    ->withMemory('256M')
    ->withNetwork(false)
    ->withOutputCaps(2 * 1024 * 1024, 512 * 1024)
    ->withReadablePaths('/data/shared')
    ->withWritablePaths('/tmp/work')
    ->withEnv(['APP_ENV' => 'test'], inherit: true);
