Introducing GraphQL Mocking in WireMock Cloud [Beta]

We're excited to announce that WireMock Cloud now supports GraphQL APIs! In beta starting now, you can mock GraphQL APIs for design, dev, test and CI just like we support for REST and GRPC.

Why This Matters for GraphQL Teams

GraphQL has taken off in recent years, but its tooling ecosystem still lags behind REST. While teams relying on OpenAPI have long enjoyed mature tools for mocking, testing, and simulation, GraphQL teams often have to build their own mocks from scratch. WireMock's new GraphQL support closes that gap.

This is especially big for teams who:

• Need to develop front-end features before a GraphQL backend is ready
• Want to simulate different responses and edge cases
• Depend on fast, reliable end-to-end and integration testing
• Are managing complex services with GraphQL APIs and need isolation during CI/CD

What You Can Do with WireMock + GraphQL

End-to-End and Integration Testing

Stub out dependent GraphQL services and return consistent responses for tests. Simulate success and error scenarios without needing the real service.

Frontend Development Without a Backend

Let frontend teams work in parallel by mocking expected GraphQL queries and returning realistic sample data.

Contract Testing

Catch breaking changes early by ensuring your GraphQL queries and responses adhere to an expected contract.

Run in CI/CD Pipelines

Spin up a WireMock instance with GraphQL stubs as part of your build pipeline to validate application behavior automatically.

Built for the GraphQL Shape of Things

GraphQL differs from REST—you typically send a POST request to a single endpoint, and query structure matters more than URL paths. WireMock has built GraphQL support with this in mind:

• Semantic Matching: Queries are matched by structure, not exact string—so field order or formatting won't break your stubs.
  
  
• Response Templating: Dynamically generate mock responses using request data or query variables.
  
  
• External Data Sources: Serve mock responses from files or external systems, enabling large or dynamic test data setups.
  
  

Stateful Behavior: Use scenarios and state to simulate flows like authentication, pagination, or mutation effects that evolve over time.

Try the Beta and Share Feedback

WireMock's GraphQL support is in beta and available in WireMock Cloud and WireMock OSS. Now's the perfect time to try it out, test your setup, and help shape the future of GraphQL testing.
