In larger systems, test data isn t just a technical problem anymore, it becomes a governance problem.
Different services, different schemas, different teams. Some rely on shared fixtures, others on generators, some add an extra abstraction layer (GraphQL, contract mocks, API gateways).
How do you handle:
Ownership of test data per service?
Keeping schemas in sync with production APIs?
Preventing teams from breaking each other s tests via shared data?
TestSeed is an API-first tool for deterministic, schema-driven test data.
Instead of random generators or brittle fixtures, TestSeed lets teams define reusable seeds from OpenAPI, GraphQL, or custom schemas and generate identical datasets across local dev and CI/CD.
This makes integration test failures reproducible, eliminates flaky tests, and keeps microservice pipelines reliable.
