rspec-grpc-testing

RSpec tests for gRPC services validate unary and streaming RPC methods, error handling with status codes, and interceptors. Write specs that cover success, failure, and edge cases using a test-first approach with isolated test doubles and comprehensive assertions.

Yes. RSpec supports testing unary RPC calls and server-streaming patterns. Unary tests verify single request-response cycles; streaming tests validate multiple responses, completion signals, and error states across the stream lifecycle.

Verify gRPC error handling by asserting on status codes and error messages in your RSpec specs. Test that your service raises the correct gRPC status (e.g., NOT_FOUND, INVALID_ARGUMENT) with descriptive messages for invalid inputs and failure conditions.

Yes. RSpec can test interceptors by verifying they execute in the correct order, modify requests and responses as expected, and handle errors properly. Isolate interceptor logic with test doubles to validate behavior independently.

Write RSpec specs first that define expected unary and streaming behavior, error handling, and interceptor logic. Then implement the gRPC service code to satisfy the specs, ensuring comprehensive coverage of success paths, failure modes, and edge cases.

Yes. RSpec can test client-side code paths by mocking gRPC service responses and verifying clients handle unary responses, streaming data, and error status codes correctly. Use test doubles to isolate client logic from actual service calls.
