from protestr import provide
from protestr.specs import between, sequence, either, subset
import json


class TestUsage(unittest.TestCase):
    @provide(
        people=sequence(
            each={
                "id": str,
                "name": either("John Smith", "Jane Doe"),
                "hobbies": subset(
                    ("cycling", "swimming", "testing with protestr"),
                    n=2
                ),
                "metadata": {str: str}
            },

            # describe the sequence size
            n=between(1, 5),

            # optionally, cast to some sequence type
            type=list
        )
    )
    def test_foo(people):
        print(f"people={json.dumps(people, indent=4)}")

people=[
    {
        "id": "nFvgELbMptWisGdIDgQ",
        "name": "John Smith",
        "hobbies": [
