与PHPUnit类'mysqli'找不到 [英] With PHPUnit Class 'mysqli' is not found
问题描述
我刚开始使用 PHPUnit .我编写的一些简单测试正在运行.因此，一般而言，PHPUnit已启动并正在运行.但是MySQLi类有问题.
I just started with PHPUnit. Some simple tests I wrote are working. So in general PHPUnit is up and running. There's something wrong with the MySQLi class though.
在我的代码中，它可以正常工作.这是一行:
In my code it works fine. Here's the line:
$this->mysqli = new \mysqli($this->host, $user->getUser(), $user->getPwd(), $this->db);
在运行phpunit的情况下解析此行时，我收到以下错误消息(指向该行):
When this line is parsed running phpunit I get the following error message (pointing to that line):
PHP Fatal error: Class 'mysqli' not found in /opt/lampp/htdocs/...
两种可能性(如我所见):
Two possibilities (as I see it):
1)我缺少某些功能/扩展/配置步骤/与与MySQLi扩展一起使用的PHPUnit的正确设置有关的其他内容.
1) I'm missing some feature / extension / configuration step / something else related to a correct setup of PHPUnit working with the MySQLi extension.
编辑
如果我测试扩展名extension_loaded('mysqli')，它将在我的常规代码中返回true.如果我在测试"中执行以下操作，则会跳过测试(即返回false):
If I do test for the extension extension_loaded('mysqli') it returns true in my normal code. If I do the following within the Test it skips the test (i.e. it returns false):
if (!extension_loaded('mysqli')) {
$this->markTestSkipped(
'The MySQLi extension is not available.'
);
}
/EDIT
2)我的代码可能有问题.我正在尝试模拟User对象以建立测试连接.所以这里是:
2) There might be a problem with my code. I'm trying to mock a User object in order to make a test connection. So here it is:
<?php
class ConnectionTest extends \PHPUnit_Framework_TestCase
{
private $connection;
protected function setUp()
{
$user = $this->getMockBuilder('mysqli\User')
->setMethods(array('getUser', 'getPwd'))
->getMock();
$user->expects($this->once())
->method('getUser')
->will($this->returnValue('username'));
$user->expects($this->once())
->method('getPwd')
->will($this->returnValue('p@ssw0rd'));
$this->connection = new \mysqli\Connection($user);
}
public function testInternalTypeGetMysqli()
{
$actual = $this->connection->getMysqli();
$expected = 'resource';
$this->assertInternalType($expected, $actual);
}
protected function tearDown()
{
unset($this->connection);
}
}
经过测试的Connection类如下:
The tested Connection class looks like this:
<?php
namespace mysqli;
class Connection
{
protected $mysqli;
protected $host = 'localhost';
protected $db = 'database';
public function __construct(\mysqli\User $user)
{
$this->mysqli = new \mysqli($this->host,
$user->getUser(),
$user->getPwd(),
$this->db);
if (mysqli_connect_errno()) {
throw new \RuntimeException(mysqli_connect_error());
}
}
public function getMysqli()
{
return $this->mysqli;
}
}
解决方案
整个问题是/是一个安装问题.我正在使用提供我的PHP的 XAMPP 安装.独立安装 PHPUnit 使其使用不同的设置！因此，在我的浏览器(由XAMPP驱动)中，一切都很好，但是在我的命令行中，MySQLi扩展一直都缺失了！ Debian提供了一个名为 php5-mysqlnd 的软件包.安装此程序后一切正常！ (除非出现其他错误:-)
This whole thing is / was an installation problem. I'm using a XAMPP installation which provides my PHP. Installing PHPUnit independently makes it use a different setup! So in my browser (XAMPP powered) all was fine, but in my command line the MySQLi extension has been missing all together! Debian provides a package called php5-mysqlnd. Having this installed all works fine! (except other errors appearing :-)
推荐答案
PHPUnit通常在CLI-命令行界面中运行.
PHPUnit normally runs within the CLI - command line interface.
您所拥有的PHP与网络服务器不同.不同的二进制文件，通常也有不同的配置.
The PHP you've got there is different than with the webserver. Different binary and often a different configuration as well.
$ php -r "new mysqli();"
应该给您同样的错误.验证二进制文件和配置的位置:
Should give you the same error. Verify where the binary and configuration is located:
$ which php
还有
$ php -i | grep ini
确保您已经 mysqli类的扩展名已安装并启用.配置完成后，您应该可以完美地运行单元测试.
Ensure you've got the extension for the mysqli class installed and enabled. Once configured you should be able to run your unit-tests flawlessly.
