This fails when running a test that extends CentralAuthTestCaseUsingDatabase:

    /**
     * @dataProvider provideWfWikiID
    */
    public function testWfWikiID($expect) {
        $this->assertSame( $expect, wfWikiID() );
    }

    public function provideWfWikiID() {
        return array(
            array( wfWikiID() ),
        );
    }


    CentralAuthPluginUsingDatabaseTest::testWfWikiID with data set #0 ('wiki')
    Failed asserting that two strings are identical.

I tried to use $this->dbPrefix() inside the provider to kludge the right value and got a failure with this stacktrace which might help figure out where we could initialize $wgDBprefix to get consistent behavior:

Fatal error: Call to a member function getType() on a non-object in /vagrant/mediawiki/tests/phpunit/MediaWikiTestCase.php on line 400
