phpunit dbunit @dataProvider不起作用 [英] phpunit dbunit @dataProvider doesn't work
问题描述
我花了很多时间搜索问题出在哪里,但是我什么都没找到.
I spent a lot of time by searching where is the problem, but i haven't find anything.
它说"testAdd导致错误:缺少参数".当我运行测试时,只是没有执行dataProvider.我试图将die()放入dataProvider中,但它尚未消失.
It sais "testAdd caused an ERROR: Missing argument". Simply the dataProvider isn't executed, when I run the test. I tried to put die() into the dataProvider and it hasn't died.
这是我的代码:
class LabelEntityModelTest extends PHPUnit_Extensions_Database_TestCase
{
private static $connection = NULL;
/**
* @var \CXNS\DB\Connections\Connection
*/
private static $appConnection;
private static $table;
public function __construct()
{
if (self::$connection) {
return;
}
$pdo = new \PDO($GLOBALS['DB_DSN'], $GLOBALS['DB_USER'], $GLOBALS['DB_PASSWD']);
self::$appConnection = new \CXNS\DB\Connections\Connection(array("prefix" => "test_", "driver" => "pdo", "resource" => $pdo));
self::$appConnection->connect();
self::$connection = $this->createDefaultDBConnection($pdo, 'mysql');
self::$table = $this->createXMLDataSet(__DIR__ . '/fixtures/tables.xml');
}
protected function getDataSet()
{
return self::$table;
}
public function getConnection()
{
return self::$connection;
}
public function getAppConnection()
{
return self::$appConnection;
}
/**
* @group onlyThis
* @dataProvider providerAdd
*/
public function testAdd($labelId, $entityId)
{
$lem = new \appLibs\Labels\LabelEntityModel($this->getAppConnection(), "contacts");
$lem->add($labelId, $entityId);
$count = $this->getAppConnection()
->select("id")
->from("label_relationships")
->where("label_id = %i", $labelId)
->where("table_ref_id = %i", $entityId)
->count();
$this->assertEquals(1, $count, "insert failed");
}
public function providerAdd()
{
return array(
array(2, 3),
array(3, 4),
array(3, 4),
array(3, 4),
array(3, 4),
array(3, 4),
array(5, 7)
);
}
}
谢谢您的帮助.
推荐答案
永远不要覆盖TestCase构造函数.
PhpUnit有一个专门用于初始化目的的方法,称为setUp
和setUpBeforeClass
,因此我强烈建议您使用它.
我很确定这是造成您问题的原因.
You should never overwrite TestCase constructor.
PhpUnit has a specialized methods for initialization purposes called setUp
and setUpBeforeClass
, so I strongly suggest you to use that.
I´m pretty sure this is the cause of your problem.
