 require_once'PHPUnit / Framework.php ; 

 class ExceptionTest扩展PHPUnit_Framework_TestCase 
 {
 public function testException（）
 {
 $ this-> expectException（InvalidArgumentException :: class）; 
 //或PHPUnit 5.2 
 // $ this-> setExpectedException（InvalidArgumentException :: class）; 

 //...然后添加生成异常的测试代码
 exampleMethod（$ anInvalidArgument）; 
} 
} 
 

Does anyone know whether there is an assert or something like that which can test whether an exception was thrown in the code being tested?

http://phpunit.de/manual/current/en/writing-tests-for-phpunit.html#writing-tests-for-phpunit.exceptions.examples.ExceptionTest.php

<?php
require_once 'PHPUnit/Framework.php';

class ExceptionTest extends PHPUnit_Framework_TestCase
{
    public function testException()
    {
        $this->expectException(InvalidArgumentException::class);
        // or for PHPUnit < 5.2
        // $this->setExpectedException(InvalidArgumentException::class);

        //...and then add your test code that generates the exception 
        exampleMethod($anInvalidArgument);
    }
}
