Question

So I just started using PHPUnit and I’m writing tests for a very simple library. It only consists of two classes so I figured it would be great place to start so I can get the hang of how Unit Testing works.

I made first class tests without any problems, but second one gives me a headache because I just can’t figure out whats wrong with this. It seems to be some error with my data provider.

<?php

use PIFlex\Roulette\Roulette;

class RouletteTest extends PHPUnit_Framework_TestCase
{
    protected $roulette;

    public function setUp()
    {
        $this->roulette = new Roulette();
    }

    /*
     * @dataProvider addItemDataProvider
     */
    public function testAddItem($item)
    {
        $this->assertInstanceOf(
            'PIFlex\Roulette\Roulette',
            $this->roulette->addItem($item, 1)
        );
    }

    public function addItemDataProvider()
    {
        return array(
            array("string"),
            array(1),
        );
    }
}

It throws me the following error:

There was 1 error:

1) RouletteTest::testAddItem
Missing argument 1 for RouletteTest::testAddItem()

FAILURES!

You have wrong annotation comment. It should started with “**”, so just change:

/*
 * @dataProvider addItemDataProvider
 */

into:

/**
 * @dataProvider addItemDataProvider
 */
