WireMock Extension for gRPC

gRPC Extension for WireMock Logo

This extension allows you to use WireMock to mock gRPC services.

The extension scans for descriptor files (generated from the service’s .proto files) in the grpc subdirectory of WireMock’s root. Using these, it converts incoming messages to JSON before passing them to WireMock’s core stubbing system which allows the existing JSON matchers to be used when matching requests. It also converts JSON responses back into proto messages so that all of WireMock’s response definition features including Templating can be used.

gRPC Mocking Schema

The extension is distributed through Maven Central: org.wiremock:grpc-extension
