Test Discovery and Balancing End-to-End

We’re ready to update our agent’s tests to test everything end-to-end: the client configuring the resolver and picker, the resolver discovering the servers, and the picker picking subconnections per RPC.

Open your agent tests in internal/agent/agent_test.go and add this import:

ClientSideServiceDiscovery/internal/agent/agent_test.go

"github.com/travisjeffery/proglog/internal/loadbalance"

Then update the client function to use your resolver and picker:

ClientSideServiceDiscovery/internal/agent/agent_test.go

func client(
        t *testing.T,
        agent *agent.Agent,
        tlsConfig *tls.Config,
) api.LogClient {
        tlsCreds := credentials.NewTLS(tlsConfig)
        opts := []grpc.DialOption{
 grpc.WithTransportCredentials(tlsCreds), ...
