Testing

USD Validation NVIDIA comes with two classes to help you test your Rules.

• ValidationTestCaseMixin: A mixin for test cases to simplify testing of individual Validation Rules.

• AsyncioValidationTestCaseMixin: A mixin for asyncio test cases to simplify testing of individual Validation Rules.

ValidationTestCaseMixin

You could mix ValidationTestCaseMixin with TestCase as follows:

from unittest import TestCase

from usd_validation_nvidia.tests import ValidationTestCaseMixin


class ValidationTestCase(TestCase, ValidationTestCaseMixin): ...

An example to implement a test case would look like:

class RuleTest(ValidationTestCase):

    def test_rule(self):
        self.assertSuccess(
            asset=get_url("pass.usda"),
            rule=MyRule,
        )
        self.assertFailure(
            asset=get_url("fail.usda"),
            rule=MyRule,
        )

AsyncioValidationTestCaseMixin

You could mix AsyncioValidationTestCaseMixin with IsolatedAsyncioTestCase as follows:

from unittest import IsolatedAsyncioTestCase

from usd_validation_nvidia.tests import AsyncioValidationTestCaseMixin


class AsyncioValidationTestCase(IsolatedAsyncioTestCase, AsyncioValidationTestCaseMixin): ...

An example to implement a test case would look like:

class RuleTest(AsyncioValidationTestCase):

    async def test_rule(self):
        await self.assertSuccessAsync(
            asset=get_url("pass.usda"),
            rule=MyRule,
        )
        await self.assertFailureAsync(
            asset=get_url("fail.usda"),
            rule=MyRule,
        )

Assertions

Additionally you could verify for specific issues, for example:

class RuleTest(AsyncioValidationTestCase):

    async def test_rule(self):
        await self.assertRuleAsync(
            asset=get_url("fail.usda"),
            rule=MyRule,
            asserts=[
                IsAFailure("Invalid condition"),
            ],
        )

IsAFailure can match to multiple attributes, like message, rule, requirement, location, etc.

Fixes

class RuleTest(AsyncioValidationTestCase):

    async def test_rule(self):
        await self.assertSuggestionAsync(
            asset=get_url("fail.usda"),
            rule=MyRule,
        )
