WireMock
A tool for building mock APIs.
Overview
WireMock is a simulator for HTTP-based APIs. It enables you to stay productive when an API you depend on doesn't exist or isn't complete. It supports testing of edge cases and failure modes that the real API won't reliably produce.
✨ Key Features
- Request matching (URL, headers, body)
- Response templating
- Stateful behavior simulation
- Proxying and recording interactions
- Fault injection (delays, corrupted responses)
- Java library and standalone server
🎯 Key Differentiators
- Powerful request matching and stateful simulation
- Mature and widely adopted in the Java ecosystem
- Extensible via custom extensions
Unique Value: Provides developers with fine-grained control over HTTP traffic and API simulations directly within their code and CI/CD pipelines.
🎯 Use Cases (4)
✅ Best For
- Integration testing in CI/CD pipelines
- Creating stable test environments for microservices
💡 Check With Vendor
Verify these considerations match your specific requirements:
- Users looking for a simple GUI-based tool
- Rapid, non-technical API prototyping
🏆 Alternatives
More powerful and flexible for complex, stateful simulations compared to UI-based tools like Mockoon or Postman.
