pact-stub-server
A Pact stub server that serves mock responses for consumer-driven contract tests (Pact) so a consumer can be tested against predictable provider behaviors without calling the real provider.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
As a test stub, it likely does not enforce production-grade authz/authn. If exposed beyond a test network, treat it as an unauthenticated service and ensure it is network-restricted. TLS and secret-handling details are not verified here.
⚡ Reliability
Best When
You want a lightweight way to run consumer tests using Pact contracts and deterministic mock provider responses.
Avoid When
You need real provider integrations, strict runtime authorization/tenancy policies, or comprehensive API documentation/SDKs beyond Pact interaction contracts.
Use Cases
- • Local development of consumer applications using Pact contract tests
- • CI testing where provider availability is not required
- • Simulating provider responses for different scenarios described by Pact contracts
- • Debugging consumer behavior against contract-defined interactions
Not For
- • Production use as an always-accurate replacement for the real provider
- • Running full provider verification (this is for stubbing/consumer-side testing, not verifying provider implementations)
- • Use as a general-purpose API mocking platform beyond Pact interactions
Interface
Authentication
Stub servers typically do not provide fine-grained auth by default; authorization behavior (if any) is usually incidental or configured for test usage rather than implementing production-grade auth.
Pricing
Open-source style package; no usage-based pricing info provided.
Agent Metadata
Known Gotchas
- ⚠ Focus is on Pact interactions; capabilities and endpoints depend on the Pact contracts loaded.
- ⚠ Mismatch between the request shape and the contract interaction can yield non-intuitive 'no matching interaction' behavior.
- ⚠ Stub behavior may be sufficient for consumers but not for testing authorization/side effects as a real provider would.
