Example:
use Google\Cloud\ServiceBuilder;
$cloud = new ServiceBuilder();
$storage = $cloud->storage();
$bucket = $storage->bucket('my-bucket');
$acl = $bucket->acl();
public function testUpdate()
{
$accessControl = ['entity' => 'allAuthenticatedUsers', 'role' => 'WRITER'];
$this->connection->patchAcl(Argument::any())->willReturn($accessControl);
$acl = new Acl($this->connection->reveal(), 'bucketAccessControls', ['bucket' => 'bucket']);
$this->assertEquals($accessControl, $acl->update('allAuthenticatedUsers', 'WRITER'));
}
