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: etcd_config_test.go
    path of file: ./repos/etcd/tests/e2e
    
    the code of the file until where you have to start completion: // Copyright 2016 The etcd Authors

func TestSnapshotCatchupEntriesFlag(t *testing.T) {
	e2e.SkipInShortMode(t)

	ctx, cancel := context.WithTimeout(context.Background(), 10*time.Second)
	defer cancel()

	proc, err := e2e.SpawnCmd([]string{e2e.BinPath.Etcd, "--experimental-snapshot-catchup-entries", "1000"}, nil)
	require.NoError(t, err)
	require.NoError(t, e2e.WaitReadyExpectProc(ctx, proc, []string{"\"snapshot-catchup-entries\":1000"}))
	require.NoError(t, e2e.WaitReadyExpectProc(ctx, proc, []string{"serving client traffic"}))
	require.NoError(t, proc.Stop())

	// wait for the process to exit, otherwise test will have leaked goroutine
	if err := proc.Close(); err != nil {
		t.Logf("etcd process closed with error %v", err)
	}
}
