junit5 VS Minestom

To make the above check work we need to wrap it in JUnit test:

Java / JUnit

Next, you need to install a testing framework that will be used for performing unit testing in your project. Several testing frameworks are available depending on the programming language used to create an application. For example, JUnit is commonly used for Java apps, pytest for Python apps, NUnit for .NET apps, Jest for JavaScript apps, and so on. We’ll use the Jest framework for this tutorial since we are using JavaScript.

This repository provides a BuildImageTest that uses the buildpack to create a native image. It then tests the native image, using Testcontainers and JUnit. Building the native image with AOT processing, as part of a test, takes minutes not seconds, and should not be part of normal "inner loop" development. So the BuildImageTest is in a separate sourceSet and can be executed independently. This is a very powerful pattern, that I'm just getting started with. I would love to hear your thoughts on this pattern or other alternatives to it.

To get started with testing, search for a popular testing framework for your programming language. PHP has PHPUnit, for example. Java has JUnit. Flutter apps use Flutter Driver. No matter your language or framework, there is a testing framework that will work for your app.

Another library which may be of use to you once you've gotten to grips with the basics of Java is JUnit. JUnit provides functionality for unit testing, allowing you to more easily see if your code is working as expected/if you've accidentally broken anything, via letting you write tests that can check if your code is behaving as expected or not.

In my last episode (https://youtu.be/cs2Wu9Co-2s) I said that we shouldn't use JUnit @BeforeEach to setUp test fields. Christoph Sturm (https://twitter.com/globalo) pointed out that there is an, erm, feature of JUnit 5 that means that we sometimes have to use @BeforeEach methods to initialise resources if we want them to be released in @AfterEach. The bug report is here https://github.com/junit-team/junit5/issues/1358 With or without this feature, we probably should use @BeforeEach to run code that will allocate non-memory resources that we need to free in @AfterEach, if only for symmetry. I suppose that also applies to any side-effects that we need to be reverted and that are not confined to the state of the test fixture.

Testing tools on the JVM stopped using reflection about twenty years ago, they all use annotations these days (e.g. https://testng.org, https://junit.org). Rust has annotations too, obviously.

Testcontainers is a Java library that supports JUnit tests providing lightweight instances of anything that we can run in a Docker container.

- What server software or framework to use. Ideally, if you dont need too much vanilla features (world generation, all mobs & items implemented, etc), I'd use something lightweight that is not based off of the vanilla server software. There are a few projects like this on github, including: https://github.com/Minestom/Minestom , https://github.com/feather-rs/feather , https://github.com/KryptonMC/Krypton , https://github.com/df-mc/dragonfly (bedrock). Which one you use will probably depend mostly on your preference. - You will need a way to store data separate from the servers. A database like postgres should work. There are a lot of different databases tho!

Even if performance is your worry, Minestom is an open-source barebones reimplementation of the minecraft server. With this, you can make extremelly custom things and let people connect using the default vanilla client. Of coruse, you can pair this with a mod if you want to.

Depends on what you're doing on said server. If it doesn't require vanilla mechanics then Minestom might suit the job well. Other than that, I'd recommend Paper, Purpur or Pufferfish.

It's unlikely to achieve have such performance and feature using Paper/Bukkit/Spigot or the one provided by Mojang. If you want to write your own server-side software, you could use Minestom.

This is quite a difficult questions because it depends on which type of Minecraft is currently being used (java, bedrock, education). The hardware available for the server as well as the ages of the students. Normal Minecraft servers are notoriously single threaded which makes it hard to host a server for 75 without good hardware. You could look into a project called minestom which is a nice library for making a multi threaded server, but it would require the students to program the server themselves. Which definitely could be fun and educational, but isn't doable with younger students

It is called Minestom. Its not done, but here is the website and discord. If you check out the showcase channel in the discord you'll see some pretty cool stuff they've made with the current program.

Im experimenting with Minestom and I want to make some crazy stress tests (1k users).

Also to add to this, if you don't need full vanilla functionality and are more focus on higher player count than something slightly more experimental but more performant might be your best bet like GlowstoneMC (glowstone supports paper plugins) or Minestrom
