Grid Walker - Instructions

About Page

Grid Walker gives you a small rule-based movement space.

Use it to practice:

• boundary and edge testing
• movement rule modelling
• keyboard interaction
• checking invalid moves
• inspecting grid state in the DOM or JavaScript

Exploratory Testing

Map the grid as you play. Track coordinates, moves, expected result, and actual result.

Workshop Challenges

Use the game as a small state-modelling exercise:

• find at least three bugs
• get the highest score you can
• compare mouse movement with keyboard movement
• work out exactly when the game thinks you have exited the grid
• inspect the generated table cells, scores, classes, and coordinates

Useful things to watch:

• atCell, moves, score, and status
• each cell’s id, score attribute, and CSS class
• differences between clicking cells and using arrow keys
• what happens before a start cell is selected

Questions to guide testing:

• Can you move only left, right, up, and down?
• Can you move back onto a visited cell?
• What happens if you try to exit from the wrong side?
• Does the page text match the actual win condition?
