Let’s Build Our First AI UX Testing Project

Now that we understand what AI UX testing is and have the tools ready, it’s time to start building. In this tutorial, we’ll create a basic Python project using the Mesa library to simulate how users interact with a simple interface grid.

Table of Contents

Step 1: Project Folder Structure

First, create a new project folder:

mkdir ai-ux-simulation
cd ai-ux-simulation

Create the main files you’ll need:

touch model.py agent.py server.py run.py

Step 2: Install Dependencies

Make sure you’ve installed the necessary Python libraries:

pip install mesa

Step 3: Define a Simple UX Environment

In model.py, define a basic Mesa model:

from mesa import Model
from mesa.space import MultiGrid
from mesa.time import RandomActivation
from agent import UserAgent

class UXModel(Model):
    def __init__(self, num_agents, width, height):
        self.num_agents = num_agents
        self.grid = MultiGrid(width, height, True)
        self.schedule = RandomActivation(self)

        for i in range(self.num_agents):
            a = UserAgent(i, self)
            self.schedule.add(a)
            x, y = self.random.randrange(self.grid.width), self.random.randrange(self.grid.height)
            self.grid.place_agent(a, (x, y))

    def step(self):
        self.schedule.step()

Step 4: Create a Simulated User Agent

In agent.py, define a simple agent that moves randomly:

from mesa import Agent

class UserAgent(Agent):
    def __init__(self, unique_id, model):
        super().__init__(unique_id, model)

    def step(self):
        possible_steps = self.model.grid.get_neighborhood(
            self.pos, moore=True, include_center=False)
        new_position = self.random.choice(possible_steps)
        self.model.grid.move_agent(self, new_position)

Step 5: Run the Simulation

In run.py:

from model import UXModel

model = UXModel(num_agents=5, width=10, height=10)
for i in range(20):
    model.step()

What’s Next?

You now have a working AI UX testing project that simulates users moving in a digital space. Tomorrow, we’ll visualize their movement and interactions using mesa.visualization.
