尝试为我的Phalcon测试设置固定装置，但失败。 您能找出我的实现方式出了什么问题吗？
使用“ getConnection”功能连接到数据库成功
创建dataSet（YAML类型）
创建getDataSet函数，但无法设置固定装置并进行清理
<?php
use Phalcon\Di;
use Phalcon\Mvc\Model\Manager as ModelsManager;
use Phalcon\Test\UnitTestCase as PhalconTestCase;
use PHPUnit\DbUnit\TestCaseTrait;
require_once "CustomHelper.php";
// config of phpunit
abstract class UnitTestCase extends PhalconTestCase
{
use TestCaseTrait;
/**
* @var bool
*/
private $_loaded = false;
public function setUp()
{
parent::setUp();
$di = Di::getDefault();
$di->set(
"modelsManager",
function () {
return new ModelsManager();
}
);
$di["modelsMetadata"] = function () {
$metadata = new \Phalcon\Mvc\Model\Metadata\Files(
[
"metaDataDir" => joinPaths(__DIR__, "/path/to/metadata/"),
]
);
return $metadata;
};
$di->setShared('mockControllerHelper', new mockControllerHelper());
$di->setShared('helper', new Helpers());
$di->setShared('config', function () {
return require CONFIG_DIR . 'app.php';
});
$di->setShared('db', function () {
$config = $this->getConfig();
// database configuration from app.php
$class = 'Phalcon\Db\Adapter\Pdo\\' . $config->database->adapter;
$params = [
'host' => $config->database->host,
'username' => $config->database->username,
'password' => $config->database->password,
'dbname' => $config->database->dbname,
];
if ($config->database->adapter == 'Postgresql') {
unset($params['charset']);
}
$connection = new $class($params);
return $connection;
});
$this->setDi($di);
$this->_loaded = true;
}
public function tearDown()
{
/* This static call cleans up the Mockery container used by the current test, and run any verification tasks needed for our expectations. */
\Mockery::close();
}
/**
* Check if the test case is setup properly
*
* @throws \PHPUnit_Framework_IncompleteTestError;
*/
public function __destruct()
{
if (!$this->_loaded) {
throw new \PHPUnit_Framework_IncompleteTestError(
"Please run parent::setUp()."
);
}
}
// Setting part of dbunit
static private $pdo = null;
private $conn = null;
final public function getConnection()
{
require CONFIG_DIR . 'app.php';
if ($this->conn === null) {
if (self::$pdo == null) {
self::$pdo = new PDO(
'mysql:host='. $globalConfig->database->host .';dbname=test',
$globalConfig->database->username,
$globalConfig->database->password
);
}
$this->conn = $this->createDefaultDBConnection(self::$pdo, 'dbname=test');
}
return $this->conn;
}
}
<?php
namespace Test\Controllers;
use PHPUnit\DbUnit\DataSet\YamlDataSet;
class DatabaseTest extends \UnitTestCase
{
protected function getDataSet()
{
return new YamlDataSet(__DIR__ . "/../DataSet/dataSet.yml");
}
public function testsTableRow() {
$this->assertEquals(1, $this->getConnection()->getRowCount('testRow'), "");
}
}
testRow:
-
id: 1
name: 'test'
text: 'hello, world'
Failed asserting that 0 matches expected 1.
当我在getConnection中使用真实的mysql数据库连接并调用$this->getConnection()->getRowCount('testRow')时，结果是正确的。
因此，问题似乎来自加载yaml数据集
$this->getConnection的内容是：
（执行print_r($this->getConnection(), false);）
(
[connection:protected] => PDO Object
(
)
[metaData:protected] => PHPUnit\DbUnit\Database\Metadata\MySQL Object
(
[schemaObjectQuoteChar:protected] => `
[pdo:protected] => PDO Object
(
)
[schema:protected] => dbname=test
[truncateCommand:protected] => TRUNCATE
)
)
$this->getDataSet()的内容是：
（执行print_r($this->getDataSet(), false);）
(
[tables:protected] => Array
(
[testRow] => PHPUnit\DbUnit\DataSet\DefaultTable Object
(
[tableMetaData:protected] => PHPUnit\DbUnit\DataSet\DefaultTableMetadata Object
(
[columns:protected] => Array
(
[0] => id
[1] => name
[2] => text
)
[primaryKeys:protected] => Array
(
)
[tableName:protected] => testRow
)
[data:protected] => Array
(
[0] => Array
(
[id] => 1
[name] => test
[text] => hello, world
)
)
[other:PHPUnit\DbUnit\DataSet\AbstractTable:private] =>
)
)
[parser:protected] => PHPUnit\DbUnit\DataSet\SymfonyYamlParser Object
(
)
)
答案 0 :(得分：1)
Dbunit必须执行一些设置操作，并且它们在PHPUnit\DbUnit\TestCaseTrait方法的setUp()中进行了定义（您可以看到更多的code details here。在继承PHPUnit\DbUnit\TestCase时，您基本上不需要不必担心（除了确保从测试用例中调用parent::setUp()之外），当直接从trait中使用功能时，必须确保也调用了dbunit的设置。
您可以通过如下方式实现此目标：
<?php
use Phalcon\Test\UnitTestCase as PhalconTestCase;
use PHPUnit\DbUnit\TestCaseTrait;
abstract class UnitTestCase extends PhalconTestCase
{
use TestCaseTrait {
setUp as protected dbunitSetUp;
};
public function setUp()
{
parent::setUp(); // phalcon setup
$this->dbuintSetUp(); // dbunit setup
}
}
对于上面的示例，仅包括与问题相关的行，并跳过诸如getConnection之类的其他内容。
