Testing

April 30, 2026 • Section: Stripe

References

Test Code is from https://github.com/stripe/stripe-python/tree/5202e51e114cc71182a71b980b8e2ac51eb175df/tests
fixtures3.yaml and openapi.spec3.json is from https://github.com/stripe/openapi

OpenAPI

For the latest openapi.spec3.json you need to replace all occurrences of “oneOf” with “anyOf” because stripe-mock does not support “oneOf”.
You can do this with the following command:

 sed -i 's/"oneOf"/"anyOf"/g' openapi.spec3.json

Notes

The “unsupported field in JSON schema: ‘oneOf’” error occurs because stripe-mock relies on an underlying validation library (go-jsval) that does not support the oneOf keyword introduced in OpenAPI 3.0.
