grpc-finagle interop client/server

In order to test how well grpc-finagle interoperates with other grpc stacks, we implement the [https://github.com/grpc/grpc/blob/master/doc/interop-test-descriptions.md](standard interop service).

Current status

Some of the basic interop tests work, but many need improvements.

Test implementation status

These test names are standard and defined in the above document.

• empty_unary empty (zero bytes) request and response.
• large_unary single request and (large) response. (flow control deadlock) #929
• client_streaming request streaming with single response. (flow control deadlock) #982
• server_streaming single request with response streaming.
• ping_pong full-duplex streaming. (flow control deadlock) #980
• empty_stream full-duplex streaming with zero message. #981
• timeout_on_sleeping_server fullduplex streaming on a sleeping server.
• compute_engine_creds large_unary with compute engine auth. (needs TLS) #895
• service_account_creds large_unary with service account auth. (needs TLS) #894
• jwt_token_creds large_unary with jwt token auth. (needs TLS) #893
• per_rpc_creds large_unary with per rpc token. (needs TLS) #891
• oauth2_auth_token large_unary with oauth2 token auth. (needs TLS)
• cancel_after_begin cancellation after metadata has been sent but before payloads are sent.
• cancel_after_first_response cancellation after receiving 1st message from the server.
• status_code_and_message status code propagated back to client.
• custom_metadata server will echo custom metadata. (needs metadata support) #986
• unimplemented_method client attempts to call unimplemented method.
• unimplemented_service client attempts to call unimplemented service.

How to test a grpc-finagle server against the official grpc-go interop client.

build and run the interop server

$ ./sbt
> grpc-interop/run

build and run the grpc-go interop client.

$ go get -u google.golang.org/grpc
$ go get -u cloud.google.com/go/compute/metadata
$ go get -u golang.org/x/oauth2
$ go get -u go/src/github.com/grpc/grpc-go/interop/client/client.go
$ go build -o go-grpc-interop-client  go/src/github.com/grpc/grpc-go/interop/client/client.go
$ ./go-grpc-interop-client -use_tls=false  -test_case=empty_unary -server_port=60001

To find all the test cases you can run, use the --help flag.

$ ./go-grpc-interop-client --help

build and run the grpc-java interop client.

First, you will need gradle installed. (brew install gradle on macOS)

$ git clone https://github.com/grpc/grpc-java.git
$ cd grpc-java
$ ./gradlew installDist -PskipCodegen=true
$  ./run-test-client.sh --use_tls=false --test_case=empty_unary --server_port=60001
