Testing

The examples below assume that $GRPC_ROOT is set to the directory that contains the grpc repository, and $GO_BIN is the directory that contains the go client and server executables. ($> export GO_BIN=...).

Common test

The test suite grpc_SUITE.erl can be executed using erlang.mk:

make ct

Testing against the GO implementation

To test the Erlang implementation against the reference implementation in go, install the go examples:

go install google.golang.org\grpc\examples\route_guide\client
go install google.golang.org\grpc\examples\route_guide\server

Testing the Erlang client against the go server

• start the go server without any arguments: $GO_BIN/server.
• run the "test_grpc_client":

$> make shell
1> cd("test").
2> c(test_grpc_client).
3> test_grpc_client:run(tcp). %% run a test without ssl

To test with tls:

• stop the go server (^C)
• start the go server again, this time with tls:

$> $GO_BIN/server -tls -cert_file $GRPC_ROOT/test/certificates/server1.pem -key_file $GRPC_ROOT/test/certificates/server1.key -json_db_file $GRPC_ROOT/test/testdata/route_guide_db.json

Run the test client with the tls option:

4> test_grpc_client:run(tls).

Testing the Erlang server against the go client

Start the Erlang server (without tls):

$> make shell
1> cd(test).
2> c(test_grpc_server).
3> test_grpc_server:run(tcp).

Run the go client:

$> $GO_BIN/client

To test with ssl:

4> test_grpc_server:stop().
5> test_grpc_server:run(ssl).

Tun the go client with ssl: $> $GO_BIN/client -tls -ca_file $GRPC_ROOT/test/certificates/My_Root_CA.crt -server_host_override localhost
