Support for OpenAPI Links in Other REST API Fuzzers

Ascertain whether publicly available REST API fuzzers other than EvoMaster implement support for the OpenAPI “links” specification, enabling link-aware test generation.

Background

The paper extends EvoMaster to exploit OpenAPI links so that values extracted from earlier responses can be used as inputs for subsequent requests, maintaining this behavior in generated tests to avoid flakiness.

The authors explicitly note uncertainty about whether other REST API fuzzers provide analogous support for OpenAPI links, highlighting a gap in knowledge about tool capabilities across the ecosystem.

References

We do not know if any other fuzzers support OpenAPI links.
