You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: grpc_test.go
    path of file: ./repos/zap/zapgrpc/internal/test
    
    the code of the file until where you have to start completion: // Copyright (c) 2021 Uber Technol
    
func TestLoggerV2(t *testing.T) {
	core, observedLogs := observer.New(zapcore.InfoLevel)
	zlog := zap.New(core)

	grpclog.SetLoggerV2(zapgrpc.NewLogger(zlog))

	grpclog.Info("hello from grpc")

	logs := observedLogs.TakeAll()
	require.Len(t, logs, 1, "Expected one log entry.")
	entry := logs[0]

	assert.Equal(t, zapcore.InfoLevel, entry.Level,
		"Log entry level did not match.")
	assert.Equal(t, "hello from grpc", entry.Message,
		"Log entry message did not match.")
}
