SyncOnStart test cases

SyncOnStart.cs

using UdonSharp;
using UnityEngine;
using VRC.SDKBase;

namespace FairlySadPanda.TestCases
{
    [UdonBehaviourSyncMode(BehaviourSyncMode.Manual)]
    public class SyncOnStart : UdonSharpBehaviour
    {
        [SerializeField] private string testCaseName;
        [SerializeField] private string dataToSync = "the quick brown fox jumped over the lazy dog";
        [UdonSynced] private string newSyncedData;
        private string oldSyncedData;

        public void Start()
        {
            Debug.Log($"{buildPrefix()} sync on start triggered for {gameObject}");
            
            if (!Networking.IsOwner(gameObject))
            {
                Debug.Log($"{buildPrefix()} we don't think you're the owner of {gameObject} so we're not going to sync anything...");

                return;
            }

            if (oldSyncedData == dataToSync || newSyncedData == dataToSync)
            {
                Debug.Log($"{buildPrefix()} not syncing anything, test already run");

                return;
            }

            newSyncedData = dataToSync;
            
            RequestSerialization();
        }

        public override void OnPreSerialization()
        {
            Debug.Log($"{buildPrefix()} successfully reached preserialization of behaviour {gameObject}");
        }

        public override void OnPostSerialization(VRC.Udon.Common.SerializationResult result)
        {
            Debug.Log($"{buildPrefix()} successfully reached postserialization of behaviour {gameObject}");
        }

        public override void OnDeserialization(VRC.Udon.Common.DeserializationResult result)
        {
            if (newSyncedData == oldSyncedData)
            {
                Debug.LogWarning($"{buildPrefix()} successfully reached deserialization of behaviour {gameObject}: synced value is '{newSyncedData}' which isn't new data. Is this intended?");
                
                return;
            }
            
            Debug.Log($"{buildPrefix()} successfully reached deserialization of behaviour {gameObject}: synced value is '{newSyncedData}'");
            oldSyncedData = newSyncedData;
        }

        private string buildPrefix()
        {
            return $"[TEST] [{testCaseName}] [{Networking.LocalPlayer.displayName}:{Networking.LocalPlayer.playerId}]";
        }
    }
}

For the tests involving interact I used this code:

using UdonSharp;
using UnityEngine;
using VRC.SDKBase;

namespace FairlySadPanda.TestCases
{
    [UdonBehaviourSyncMode(BehaviourSyncMode.None)]
    public class EnableOnInteract : UdonSharpBehaviour
    {
        [SerializeField] private GameObject objectUnderTest;
        [SerializeField] private bool setOwnerWhenRunTest;

        public override void Interact()
        {
            if (objectUnderTest.activeSelf)
            {
                Debug.LogError($"object {objectUnderTest.name} is already active, test is invalid!");

                return;
            }
            
            objectUnderTest.SetActive(true);

            if (setOwnerWhenRunTest)
            {
                Networking.SetOwner(Networking.LocalPlayer, objectUnderTest);
            }
            
            Destroy(this);
        }
    }
}
