PHPUnit：dataProvider在PHPUnit_Framework_TestCase的子类中不起作用

Question

I'm using classes extended from PHPUnit_Framework_TestCase in my tests. And it seems like the @dataProvider doesn't work for these extended classes.

Here's just a simple test

namespace HH\Api\V10;

class StupidityTest extends TestCase
{
    /**
     * @dataProvider additionProvider
     */
    public function testAdd($a, $b, $expected)
    {
        $this->assertEquals($expected, $a + $b);
    }

    public function additionProvider()
    {
        return [
          [0, 0, 0],
          [0, 1, 1],
        ];
    }
}

phpunit returns this error:

If I use \\PHPUnit_Framework_TestCase instead of TestCase then it works fine. But it's not working for these extended classes: TestCase & ApiTestCase .

TestCase class

namespace HH\Api\V10;

use HH\Api\ApiTestCase;

class TestCase extends ApiTestCase
{
}

ApiTestCase class

namespace HH\Api;

use GuzzleHttp\Client;
use GuzzleHttp\Exception\RequestException;
use GuzzleHttp\Message\Response;

class ApiTestCase extends \PHPUnit_Framework_TestCase
{
    protected $client = null;

    public function __construct()
    {
        parent::__construct(); // <--have called parent constructor
        $this->client = new Client([
            'base_url' => $this->url(),
        ]);
    }
    ....
}

Any help would be really appreciated. Thanks

Answer 1

Finally figured out why it didn't work out.

The constructor of the sub class needs to be identical to that of the parent class PHPUnit_Framework_TestCase .

class ApiTestCase extends \PHPUnit_Framework_TestCase
{
    protected $client = null;

    public function __construct($name = null, array $data = array(), $dataName = '')
    {
        parent::__construct($name, $data, $dataName);
        ...
    }
 ...
}

But I found out that the better way to do this was not through the constructor but with fixtures.

public function setUp()
{
    $this->client = new Client([
        'base_url' => $this->url(),
    ]);
}

您应该使用setUp夹具来设置$client
