laravel-testing（Laravel 测试）

Laravel Testing

Agent Workflow (MANDATORY)

Before ANY implementation, use TeamCreate to spawn 3 agents:

1. fuse-ai-pilot:explore-codebase - Analyze existing test patterns
2. fuse-ai-pilot:research-expert - Verify Pest/PHPUnit docs via Context7
3. mcp__context7__query-docs - Check assertion and mocking patterns

After implementation, run fuse-ai-pilot:sniper for validation.

Overview

Decision Guide: Test Type

What to test?
├── HTTP endpoint → Feature test
├── Service/Policy logic → Unit test
├── Code structure → Arch test
├── External API → Mock with Http::fake()
├── Mail/Queue/Event → Use Fakes
└── Database state → assertDatabaseHas()

Decision Guide: Test Strategy

Coverage strategy?
├── Feature tests (70%) → Critical flows
├── Unit tests (25%) → Business logic
├── E2E tests (5%) → User journeys
└── Arch tests → Structural rules

Critical Rules

1. Use RefreshDatabase for database isolation
2. Use factories for test data (never raw inserts)
3. Mock external services - Never call real APIs
4. Test edge cases - Empty, null, boundaries
5. Run parallel - pest --parallel for speed

Quick Reference

// Feature test
it('creates a post', function () {
    $user = User::factory()->create();

    $this->actingAs($user)
        ->postJson('/api/posts', ['title' => 'Test'])
        ->assertCreated()
        ->assertJsonPath('data.title', 'Test');

    $this->assertDatabaseHas('posts', ['title' => 'Test']);
});

// With dataset
it('validates emails', function (string $email, bool $valid) {
    // test logic
})->with([
    ['valid@test.com', true],
    ['invalid', false],
]);

// Mock facade
Mail::fake();
// ... action ...
Mail::assertSent(OrderShipped::class);

Commands

# Run all tests
php artisan test

# Pest directly
./vendor/bin/pest

# Parallel execution
./vendor/bin/pest --parallel

# Filter by name
./vendor/bin/pest --filter "user can"

# Coverage
./vendor/bin/pest --coverage --min=80

# Profile slow tests
./vendor/bin/pest --profile

Best Practices

DO

• Use RefreshDatabase trait
• Follow AAA pattern (Arrange-Act-Assert)
• Name tests descriptively
• Test one thing per test
• Use factories for data

DON'T

• Create test dependencies
• Call real external APIs
• Use production database
• Skip edge cases
