Testing and Debugging

This outline provides information on testing and debugging within the pacman-typescript project.

Testing

The project leverages a variety of testing strategies, including:

Unit Tests:

• Located within the tests directory.
• Utilize the mocha testing framework with chai assertion library.

Integration Tests:

• Also located within the tests directory.
• Utilize the mocha testing framework with chai assertion library.

Example Unit Test (tests/game.test.js)

import { expect } from 'chai';
          import Game from '../src/game';
          
          describe('Game', () => {
            it('should initialize with a default score of 0', () => {
              const game = new Game();
              expect(game.score).to.equal(0);
            });
          
            it('should increase the score when a pellet is eaten', () => {
              const game = new Game();
              game.eatPellet();
              expect(game.score).to.equal(10); 
            });
          });
          

Example Integration Test (tests/game.integration.test.js)

import { expect } from 'chai';
          import Game from '../src/game';
          import Board from '../src/board'; 
          
          describe('Game Integration', () => {
            it('should move the Pacman correctly', () => {
              const game = new Game();
              const board = new Board(); 
              game.board = board;
          
              game.movePacman('right');
              expect(game.pacman.x).to.equal(1);
            });
          });
          

Running Tests:

• Utilize the npm command npm test in the project’s root directory.

Debugging

Debugging Techniques:

• Leverage the browser’s developer tools (e.g., Chrome DevTools, Firefox Developer Tools) for interactive debugging, including:
  • Setting breakpoints.
  • Inspecting variables and objects.
  • Stepping through code execution.
• Utilize the console.log() function for logging output to the browser’s console.
• Employ debugging techniques within the mocha testing framework.

Example Debugging Output:

console.log('Pacman position:', game.pacman.x, game.pacman.y);
