How to use multiple dataproviders in a single codeception(a php based test automation framework) test? - codeception

Question

I use codeception which is a php based test automation framework.
I need to use multiple dataproviders in a single test class.
I know how to use a single dataprovider per test; example of my code below:
use Codeception\Example;
/**
* #dataProvider charProvider
*/
public function sampleTest(Example $data) {
//iterating through the array of data points contained in the data provider:
$data_point_char = iterator_to_array($data->getIterator());
print_r($data_point_char['data']);
}
/**
* #return array
*/
protected function charProvider() {
return[
['data' => 'a'],
['data' => 'b']
];
}
Now my requirement is to use another data provider: numProvider() within the same test:
protected function numProvider() {
return[
['data' => 1],
['data' => 2]
];
}
I am not sure, how the iterator_to_array() will reference this second data provider and iterate through it as in the code I used, this iterator_to_array() method is using a pretty generic parameter:
iterator_to_array($data->getIterator())
Not quite getting how individual data provider can be referenced in this manner?
And if individual dataproviders can be referenced independently within a same test, then following that multiple dataproviders can be used within the same test.
Kindly suggest how to achieve this?
Thanks in advance

Codeception 5 allows to specify multiple data providers for test method. Test method is executed repeatedly with each data item from each data provider, in your example sampleTest will be executed 4 times.
It is completely unnecessary to use iterator_to_array($data->getIterator()); for converting instance of Example class to array. Example implements ArrayAccess interface, so data from data provider can be accessed as array element - $example['data'].
/**
* #dataProvider charProvider
* #dataProvider numProvider
*/
public function sampleTest(Example $example) {
var_dump($example['data']);
}
