Question

I have a test method that receives an array as an argument, and I want to feed the data from a data provider method?

how can that be achieved?

public function dataProvider(){
        return array(array(
                'id'=>1,
                'description'=>'',
        ));
}

/**
 * @dataProvider dataProvider
 */
public function testAddDocument($data){
// data here shall be an array provided by the data provider
// some test data here
}

What happens is that it passes the value of ‘id’ key …etc

I want to pass the whole array

Data provider methods must return an array containing one array for each set of arguments to pass to the test method. To pass an array, include it with the other arguments. Note that in your sample code you’ll need another enclosing array.

Here’s an example that returns two sets of data, each with two arguments (an array and a string).

public function dataProvider(): array
{
    return
        [// data sets
            [// data set 0
                [// first argument data set 0
                    'id'          => 1,
                    'description' => 'this',
                ],
                'foo',//second argument data set 0
            ],
            [//data set 1
                [//first argument data set 1
                    'id'          => 2,
                    'description' => 'that',
                ],
                'bar',//second argument data set 1       
            ],
        ];
}

Important: Data provider methods must be non-static. PHPUnit instantiates the test case to call each data provider method.
