​
Step 1: Add the dependency

// build.gradle
dependencies {
    compileOnly files(rootProject.ext.hytaleJar)
    compileOnly files("${rootDir}/libs/HRTK-API.jar")
}

​
Step 2: Write a test class

Create a new file anywhere in your mod’s source: 
package com.example.mymod.tests;

import com.frotty27.hrtk.api.annotation.*;
import com.frotty27.hrtk.api.assert_.*;
import com.frotty27.hrtk.api.context.*;

@HytaleSuite("Quickstart Tests")
public class QuickstartTests {

    @HytaleTest("Math works")
    void testMath() {
        HytaleAssert.assertEquals(4, 2 + 2);
    }

    @HytaleTest
    void testStringContains() {
        HytaleAssert.assertContainsString("world", "hello world");
    }

    @HytaleTest
    void testExceptionThrown() {
        HytaleAssert.assertThrows(NumberFormatException.class, () -> {
            Integer.parseInt("not a number");
        });
    }

    @HytaleTest
    void testCodecRoundTrip() {
        // Test that your component's codec serializes and deserializes correctly
        CodecAssert.assertRoundTrip(MyComponent.CODEC, new MyComponent("test", 42));
    }

    @EcsTest
    void testComponentInECS(EcsTestContext ctx) {
        // Create an entity and add a component
        var entity = ctx.createEntity();
        ctx.putComponent(entity, MyComponent.TYPE, new MyComponent("hello", 1));
        ctx.flush();

        // Verify it's there
        EcsAssert.assertHasComponent(ctx.getStore(), entity, MyComponent.TYPE);
    }
}

​
Step 3: Build your mod

./gradlew build
Your test classes compile into your mod JAR alongside your regular code.

​
Step 4: Install and run

  1. Place your mod JAR in your server’s mods folder
    • Singleplayer: %APPDATA%\Hytale\UserData\Mods\
    • Dedicated server: <your-server-root>/mods/
  2. Place HRTK.jar in the same mods folder
  3. Start the server
  4. Run /hrtk run

​
Expected output

=== HRTK: MyMod ===
  Quickstart Tests
    [PASS] Math works (1ms)
    [PASS] testStringContains (0ms)
    [PASS] testExceptionThrown (1ms)
    [PASS] testCodecRoundTrip (2ms)
    [PASS] testComponentInECS (3ms)

Results: 5 passed, 0 failed, 0 skipped (7ms total)
