Test Quality Check

Analyze PHP test code for quality and best practices.

Quality Patterns

1. Test Structure (AAA Pattern)

// BAD: Mixed arrange/act/assert
public function testOrderTotal(): void
{
    $order = new Order();
    $this->assertEquals(0, $order->getTotal());
    $order->addItem(new Item('A', 10));
    $order->addItem(new Item('B', 20));
    $this->assertEquals(30, $order->getTotal());
    $order->applyDiscount(5);
    $this->assertEquals(25, $order->getTotal());
