Review Comment:
This suggestion will not work out-of-the-box, but since you're trying to
verify the data and the schema, you could do something like this:
```suggestion
table))
assert_that(
result | beam.Map(lambda x: {id: x.id, name:x.name, type: x.type}),
equal_to([
{id:3, name:'customer1', type:'test'},
{id:1, name:'customer1', type:'test'},
{id:2, name:'customer2', type:'test'},
{id:4, name:'customer2', type:'test'}
]))
self.assertEqual(result.schema, {'id': 'INT64', 'name': 'STRING',
'type': 'STRING'})
```
