voluptuous: list of dictionaries. full compliance

Question

test_data = [{'field1': 'value1',
              'field2': 1},
             {'field1': 'value3',
              'field2': 2}
             ]


schema = Schema([
    {Required('field1'): 'value1',
     Required('field2'): int},
    {Required('field1'): 'value3',
     Required('field2'): int}
    
])

assert schema(test_data)

How to check that the list contains 2 dictionaries with the structure shown above? When I try to check for a full match, I get an error: voluptuous.error.MultipleInvalid: not a valid value for dictionary value @ data[1]['field1']

I am not very familiar with voluptuous, but seems like it's not meant for parsing such schema without voluptuous.ExactSequence

Your schema would look like:

schema = Schema(
    ExactSequence(
        [
            {Required('field1'): 'value1', Required('field2'): int},
            {Required('field1'): 'value3', Required('field2'): int}
        ]
    ))
