SOAP Mock Server
Test enterprise integrations without connecting to production systems. Mock WSDL-based services, simulate SOAP faults, and validate XML payloads. Works offline, no dependencies.
Full SOAP Protocol Support
Everything you need to mock enterprise SOAP web services for development and testing.
WSDL-Based Mocking
Import WSDL files to automatically generate mock endpoints. Validates requests against schema definitions.
XML Request/Response
Full XML parsing and generation with namespace support. XPath-based request matching and response templating.
SOAP Fault Simulation
Simulate server faults, client faults, and custom error conditions. Test error handling in your applications.
WS-Security Support
Mock authentication with UsernameToken, X.509 certificates, and SAML assertions. Validate security headers.
Envelope Validation
Strict SOAP envelope validation against WSDL schemas. Catch malformed requests before they hit production.
Multiple SOAP Versions
Full support for SOAP 1.1 and SOAP 1.2 protocols. Handle both Content-Type and SOAPAction headers.
Simple Configuration
Define SOAP operations, XPath-based request matching, and XML response templates in a clean YAML format. Import WSDL files for automatic schema validation.
- WSDL import: Auto-generate mocks from service definitions
- XPath matching: Route requests based on XML content
- Namespace support: Full XML namespace handling
- Fault simulation: Test error handling with SOAP faults

From legacy mainframes to modern microservices. Mockd handles your SOAP testing needs.
Legacy System Integration
Test integrations with mainframes, ERP systems, and legacy web services without connecting to production.
Enterprise Service Testing
Mock complex enterprise service buses and SOA architectures for isolated development and testing.
B2B Integration Testing
Simulate partner APIs and EDI gateways. Test business-to-business workflows without external dependencies.
Mainframe/ERP Connectivity
Mock SAP, Oracle, and mainframe SOAP endpoints. Develop without costly backend access.
Why Mockd vs SoapUI?
SoapUI is powerful but heavy. Mockd gives you lightweight, CI/CD-friendly SOAP mocking without the complexity.
| Feature | SoapUI | Mockd |
|---|---|---|
| WSDL import | Requires desktop app | CLI or config file |
| CI/CD integration | Complex setup | Single binary, easy automation |
| Resource usage | Heavy Java application | Lightweight Go binary |
| Response templating | Groovy scripting | Simple YAML templates |
| Version control | XML project files | Clean YAML configs |
| Pricing | Free tier limited | Open source, free forever |
