Agentscape is a library for creating agent-based simulations. It provides a simple API for defining agents and their behavior, and for defining the environment in which the agents interact. Agentscape is designed to be flexible and extensible, allowing

import { test as base, expect } from 'vitest'

import RandomGenerator from './RandomGenerator'


interface TestFixture {
    rng: RandomGenerator
}

const test = base.extend<TestFixture>({
    rng: new RandomGenerator(1234)
})

test('It should generate random floats between 0 and 1', ({ rng }) => {
    const result = rng.uniformFloat(0, 1)
    expect(result).toBeGreaterThanOrEqual(0)
    expect(result).toBeLessThanOrEqual(1)
    expect(Number.isInteger(result)).toBe(false)
})

test('It should generate random integers between min and max', ({ rng }) => {
    const result = rng.uniformInt(0, 10)
    expect(result).toBeGreaterThanOrEqual(0)
    expect(result).toBeLessThanOrEqual(10)
    expect(Number.isInteger(result)).toBe(true)
