Facts

Purpose

gRPC Mock is a gRPC Java testing tool for mocking service endpoints in integration or unit tests.grpcmock.org · 4 Oct 2026

Stubbing

It configures gRPC method stubs through a fluent Java API.grpcmock.org · 4 Oct 2026

Matching

Stubs can match request headers and request bodies.grpcmock.org · 4 Oct 2026

Response behavior

Responses can have configurable delays, and later invocations can return different responses.grpcmock.org · 4 Oct 2026

Supported methods

It supports unary, server streaming, client streaming, and bidirectional streaming methods.grpcmock.org · 4 Oct 2026

Verification

Tests can verify method invocations, including invocation counts, status, headers, and request messages.grpcmock.org · 4 Oct 2026

Spring Boot integration

The grpcmock-spring-boot module integrates gRPC Mock with Spring Boot tests.grpcmock.org · 4 Oct 2026

JUnit integration

The grpcmock-junit5 module provides JUnit 5 extensions, including an in-process server option.grpcmock.org · 4 Oct 2026

Test lifecycle

With the JUnit 5 extensions, mappings are cleared after each test and the server shuts down after the test class finishes.grpcmock.org · 4 Oct 2026

Concurrency limitation

In multithreaded test setups, static configuration methods can produce UNIMPLEMENTED errors because gRPC Mock uses a ThreadLocal instance.grpcmock.org · 4 Oct 2026

Project status

The site describes gRPC Mock as open source.grpcmock.org · 4 Oct 2026
