Symfony2: PHPUnit Testing-> #dataProvider sends no multipleArray - unit-testing

Question

I make UnitTesting for my application.
I have a save saveArticleIds() Method and I wrote a testing for it -> testSaveArticelIds(). I have an dataProvider articelIdsArray() whith a multiple array. The function need that array exact like this.
/**
*
* #dataProvider articleIdsArray
*
*/
public function testSavearticleIds($articleIds) {
$articleIdObjekt = new ArticleIdHandler();
$result = $articleIdObjekt->saveArticleIds($articleIds,false);
$this->assertTrue($result);
}
public function articleIdsArray() {
return array(
array(
10552 => 10552,
14314 => 14314,
21034 => 21034,
22739 => 22739,
34568 => 34568,
34572 => 34572,
35401 => 35401,
38292 => 38292,
55141 => 55141,
161764 => 161764,
181589 => 181589
)
);
}
When I run my test, I get this Error:
There was 1 error: 1) My\Bundle\ArticleBundle\Tests\Article\ArticleIdHandlerTest::testSaveArticleIds
with data set #0 (10552, 14314, 21034, 22739, 34568, 34572, 35401, 38292, 55141, 161764, 181589)
Invalid argument supplied for foreach()
Why does it show the array like I have no keys in the array? I need the array exact like in my dataProvider! Any idea?? THANKS A LOT FOR YOU HELP!!!

Answer 1

maybe try this:
public function articleIdsArray()
{
return
array(
array(
array(
10552 => 10552,
14314 => 14314,
21034 => 21034,
22739 => 22739,
34568 => 34568,
34572 => 34572,
35401 => 35401,
38292 => 38292,
55141 => 55141,
161764 => 161764,
181589 => 181589
)
)
);
}
The reason is that the first level of the array nesting is the set of data provided for each round of tests, the second level represents the arguments provided to testSavearticleIds, in the same order as in the parameter list of the function (in your example there is only one argument), the last level is just the test array itself.
Hope this helps...

Try this :
/**
* #dataProvider articleIdsArray
*/
public function testSavearticleIds($articleIds)
{
$articleIdObjekt = new ArticleIdHandler();
$result = $articleIdObjekt->saveArticleIds($articleIds,false);
$this->assertTrue($result);
}
public function articleIdsArray()
{
return array(
'scenario_one' => 10552,
'scenario_two' => 14314,
...,
);
}

Answer 3

You doesn't need to use #dataProvider in your example.
Define your method like this
public function getArticleIdsArray() {
return array(
10552 => 10552,
14314 => 14314,
21034 => 21034,
22739 => 22739,
34568 => 34568,
34572 => 34572,
35401 => 35401,
38292 => 38292,
55141 => 55141,
161764 => 161764,
181589 => 181589
);
}
and use it in your test
public function testSavearticleIds($articleIds) {
$articleIdObjekt = new ArticleIdHandler();
$result = $articleIdObjekt->saveArticleIds($this->getArticleIdsArray(),false);
$this->assertTrue($result);
}
