Question

我有一个方法，我设置了要传递的第一个参数的类型（数组）：

public function create(array $values, $options=array())
{
    // set datetime columns
    if(! isset($values['date_created']) or empty($values['date_created'])) {
        $values['date_created'] = date("Y-m-d H:i:s");
    }
    if(! isset($values['date_updated']) or empty($values['date_updated'])) {
        $values['date_updated'] = date("Y-m-d H:i:s");
    }

    return parent::create($values);
}

如何使用PHPUnit对此进行测试，它会不断发出致命错误，我猜这是预期的，但它不允许我的脚本运行：

1) UserTableTest::testCreateMethodWithInvalidArguments
Failed asserting that exception of type "PHPUnit_Framework_Error" matches expected exception "InvalidArgumentException".

我是否应该删除类型提示并使用is_array（$ values）来判断是否传递了正确的类型然后抛出异常？在PHPUnit中，我期待抛出异常。顺便说一句，下面是我的测试：

/**
* @expectedException InvalidArgumentException
*/
public function testCreateMethodWithInvalidArguments()
{
    // pass invalid argument, should be an array of values
    $result = $this->userTable->create('invalid argument type');
}

PHPUnit只需要知道你期待和异常，这样它就可以正确处理它并报告它。

 public function testExceptionHasRightMessage()
{
    $this->setExpectedException(
      'InvalidArgumentException', 'Right Message'
    );
    throw new InvalidArgumentException('Some Message', 10);
}

这是从PHP Unit Documentation - Writing Unit Tests

的示例2.11中提取的
