PHPUnit Selenium2Testcase not working with data provider

Question

I have the following PHP unit test case.

For checking purposes I commented out the actual test (even with the ->url() call it does not work)

<?php

class BasicTest extends \PHPUnit_Extensions_Selenium2TestCase
{
    static $browsers = array(
        'chrome28win7' =>
            array(
                'browserName' => 'chrome',
                'desiredCapabilities' => array(
                    'version' => '28',
                    'os' => 'Windows',
                    'os_version' => '7',
                    'resolution' => '1280x1024',
                ),
            ),

    );

    /**
     * @dataProvider urlDataProvider
     * @param $path
     */
    public function testUrlScreenshot($path)
    {
        return; // for checking
        $this->url(env('BROWSER_BASE') . $path);
    }

    public static function urlDataProvider()
    {
        $list = <<<EOL
datenschutz.html
impressum.html
EOL;
        $plainArray = explode("\n", $list);

        $result = array();

        foreach($plainArray as $entry) {
            $result = array($entry);
        }
        return $result;
    }
}

I am getting the following exception:

if I do not use the dataProvider annotation, I can run tests. Why is that? Is `@dataProvider

Answer 1

The exception actually covered up another error.

Debugging revealed this:

So PHP Unit raised an error because my dataset was invalid (dataset needs to be an array of arrays), which somehow made PHPUnit trying to call setupSpecificBrowser() on the exception class.

Fixing the dataset fixed the error.
