🔧 Test Implementation

Playwright Integration Testing

// advanced-screenshots.js
class ScreenshotTaker {
  async testGameContent() {
    // Load game page
    await this.page.goto('https://tjsingleton.github.io/bulletbuzz/game/');

    // Wait for game to load
    await this.page.waitForSelector('#gameCanvas');

    // Verify game is running
    const canvas = await this.page.locator('#gameCanvas');
    const isVisible = await canvas.isVisible();

    // Check for game elements
    const hasPlayer = await this.page.locator('.player').count() > 0;
    const hasEnemies = await this.page.locator('.enemy').count() > 0;

    return isVisible && hasPlayer && hasEnemies;
  }
}

Error Detection Integration

// Monitor all types of errors
page.on('console', msg => {
  if (msg.type() === 'error') {
    console.log(`❌ Console Error: ${msg.text()}`);
  }
});

page.on('response', response => {
  if (!response.ok()) {
    console.log(`❌ Network Error: ${response.url()} - ${response.status()}`);
  }
});

page.on('pageerror', error => {
  console.log(`❌ Page Error: ${error.message}`);
});

📋 Test Scenarios

1. Complete Game Session

async testCompleteGameSession() {
  // Start game
  await this.page.goto('https://tjsingleton.github.io/bulletbuzz/game/');
  await this.page.waitForSelector('#gameCanvas');

  // Wait for game to run
  await this.page.waitForTimeout(5000);

  // Check game state
  const gameState = await this.page.evaluate(() => {
    return window.game?.getGameState();
  });

  // Verify game is running
  expect(gameState.isRunning).toBe(true);
  expect(gameState.player.health).toBeGreaterThan(0);
}

2. Documentation Integration

async testDocumentationIntegration() {
  // Test game-to-docs link
  await this.page.goto('https://tjsingleton.github.io/bulletbuzz/game/');
  const docLink = await this.page.locator('a[href="../"]');
  await docLink.click();

  // Verify we're on docs page
  const currentUrl = this.page.url();
  expect(currentUrl).toContain('tjsingleton.github.io/bulletbuzz');
  expect(currentUrl).not.toContain('/game/');
}

3. Logo Integration Test

async testLogoIntegration() {
  // Test logo on docs page
  await this.page.goto('https://tjsingleton.github.io/bulletbuzz/');
  const logo = await this.page.locator('img[alt*="BulletBuzz Logo"]');

  // Verify logo size
  const logoWidth = await logo.evaluate(el => el.getBoundingClientRect().width);
  expect(logoWidth).toBeGreaterThan(80);
  expect(logoWidth).toBeLessThan(120);
}
