Add multiple attribute values to product via php

Hello,
I’m trying to add multiple attributes with multiple values to a product using php, but no luck. Only last attribute value is added to the list.

$values_attr="option1,option2,option3";

$attribute_values = explode(",", $values_attr);
foreach($attribute_values as $attribute) {
    wp_set_object_terms($post_id, $attribute, "pa_test_attr", false);
}

$product_attributes['pa_test_attr'] = array(
    'name' => "pa_test_attr",
    'value' => $attribute_values,
    'position' => 0,
    'is_visible' => 0,
    'is_variation' => 0,
    'is_taxonomy' => 1
);

update_post_meta($post_id, '_product_attributes', $product_attributes);

What could be the issue? Thank you!
