🖼️ Visual Testing (Web Apps)

For UI/UX testing, use Playwright MCP to capture and Vision AI to analyze:

Capture Screenshots

code

mcp_playwright_browser_navigate(url="http://localhost:8000/[page]")
mcp_playwright_browser_take_screenshot(filename="test-screenshot.png")

Analyze with Vision AI

code

mcp_zai-mcp-server_analyze_image(
  image_path="test-screenshot.png",
  prompt="Analyze this UI: check layout, colors, spacing, alignment, accessibility issues"
)

Visual Regression Flow

•Capture baseline screenshot
•Make changes
•Capture new screenshot
•Use Vision AI to compare and validate

Validation Loop (MANDATORY)

After writing or modifying tests, always verify:

bash

composer test           # PHP tests pass
npm run test           # JS tests pass (if applicable)

TDD Feedback Loop:

•Write test → Verify it FAILS (Red)
•Implement minimal code → Verify it PASSES (Green)
•Refactor → Verify it still PASSES
•Repeat for edge cases

Instructions (TDD Workflow)

Step	Action	Verification
1	Write failing test	`composer test --filter=NewTest` → FAILS
2	Implement minimal code	`composer test --filter=NewTest` → PASSES
3	Refactor	`composer test` → ALL PASS
4	Add edge cases	Repeat steps 1-3

Pest Patterns (Laravel)

Feature Test

php

test('user can create post', function () {
    $user = User::factory()->create();
    
    $this->actingAs($user)
        ->post('/posts', ['title' => 'Test'])
        ->assertRedirect('/posts');
        
    $this->assertDatabaseHas('posts', ['title' => 'Test']);
});

Unit Test

php

test('generates slug from title', function () {
    expect((new SlugGenerator)->generate('Hello World'))
        ->toBe('hello-world');
});

Vitest Patterns (React)

tsx

describe('PostForm', () => {
    it('submits with valid data', async () => {
        const onSubmit = vi.fn();
        render(<PostForm onSubmit={onSubmit} />);
        
        await userEvent.type(screen.getByLabelText(/title/i), 'Test');
        await userEvent.click(screen.getByRole('button', { name: /submit/i }));
        
        expect(onSubmit).toHaveBeenCalled();
    });
});

Test Commands

bash

# Laravel
composer test
php artisan test --filter=PostTest
php artisan test --coverage

# React
npm run test
npm run test:watch
npm run test:coverage
