如何在 PHP 函数单元测试中处理异常

use PHPUnit\Framework\TestCase;

class ExampleTest extends TestCase
{
    public function testDivisionByZero()
    {
        $this->expectException(ArithmeticError::class);
        
        // 要测试的函数
        divide(10, 0);
    }
}

use PHPUnit\Framework\TestCase;
use Exception;

class ExampleTest extends TestCase
{
    public function testDivisionByZero()
    {
        try {
            // 要测试的函数
            divide(10, 0);
        } catch (Exception $e) {
            $this->assertInstanceOf(ArithmeticError::class, $e);
        }
    }
}

use PHPUnit\Framework\TestCase;
use Exception;

class DivideTest extends TestCase
{
    public function testDivision()
    {
        $this->assertEquals(10, divide(20, 2));
        
        $this->expectException(ArithmeticError::class);
        divide(10, 0);
        
        $this->assertInstanceOf(ArithmeticError::class, divide(0, 0));
    }
}
