Installation

To install the library, use npm:

Usage

Writing Tests

Tests in LUnit can be defined as a simple TypeScript class. Each test is treated like a module, so you'll export the class definition as the module. Here's an example:

// ReplicatedStorage/Tests/SomeTest.spec.ts
import { Test, DisplayName, Assert } from "@rbxts/lunit";

// this is the function we're testing
function sum(a: number, b: number): number {
	return a + b;
}

class TestClass {
	@Test
	sumTwoNums() {
		Assert.equals(sum(5, 5), 10);
		Assert.notEqual(sum(5, 5), 999);
	}
}

export = TestClass; // export the class as a module

Running Tests

To run your tests, use the following npm script:

// SomeScript.server.ts
import { ReplicatedStorage } from "@rbxts/services";
import { TestRunner } from "@rbxts/lunit";

const testRunner = new TestRunner([
	ReplicatedStorage.FindFirstChild("Tests"), // the folder containing all your test modules
]);

testRunner.run();
