1.20

[CubBossa]

Hey, I think integration testing for plugins could be pretty useful and wondered if there will be a 1.20 support in the future

And I wondered if there is a way to simulate player activity. For example I have this editor where players can right click a block to create a graph node in their world (used for citizens pathfinding and stuff). Could I possibly simulate a right click on a block from a player?

And if you really wanted to go crazy, there could be a record functionality to generate test classes based on what I do ingame. Like spigottester --record create graph node, then type command, right click block, what ever. then spigottester --stop generates a java.class file in the plugin dir that contains a list of player action simulations like

@Test("create graph node")
public void testCreateGraphNode() {
  Player playerA = addPlayer("a");
  Simulator simA = new Simulator();
  simA .command("abc");
  simA .chat("hello world");
  // use primitive parameters to allow client side entity testing, like if there is a clientside display entity that can be clicked
  // its basically parsed packet information instead of parsed event information, so its recording incoming packets and simulating them later
  simA .interactBlock(ClickType.RIGHT_CLICK, "world", 0.123d, 1.234d, 2.345d);
  simA .interactEntity(ClickType.RIGHT_CLICK, 123);
}

of course the assertions must be added by hand but it would help a lot to quickly do your usual tests by hand but record them at the same time.

I'd love to help you out and am more than willing to try the record feature but I'm trying to avoid nms at all cost and would hope that you could add 1.20 support

Hi, I really glad that you found this library usefull

1.20 support

Isn't this library just working on the 1.20 version?

And I wondered if there is a way to simulate player activity.

When It comes to player activity, it is not really simple and possible to simulate real player actions, since it would required to join actuall player to server. Right now as you might found addPlayer("a"); creates virtual player that has all statistics and method working however it's like ghost

Could I possibly simulate a right click on a Block from a player?

Yes, To do so, you would need to publish PlayerInteractEvent with test player as argument. It is totally possible since PluginTest has method for publishing events

' generate test classes based on what I do ingame'

This sound so cool! I would love to do that, however recentlly I don't have much time for my side projects anyway you can contribute to this project :D

Bdw you should watch this. https://www.youtube.com/watch?v=vXaWOJTCYNg

About the fake players: an alternative would be to restrict the library to offline mode servers and simulate joining players via packets. Meaning the server tracks fake clients completely managed by the framework. The advantage would be that plugins based on packets could be tested too. To improve performance I render some static entities client side in my plugins and when the player clicks such entity, events would not fire serverside.

Thanks for sharing the vid!

ok I see issue with NMS, I can fix that, no problem

Sure if you have idea how to incorporate tracking ingoing and outgoing packets in the single test lifespan, we can implement that

Righto, I'll start by making a test suite for my plugin in 1.20 when you updated and then from that I'd contribute and test my changes on that suite
