I want to insert post programatically so here is the code to add one:

global $user_ID;
$new_post = array(
    'post_title' => 'My New Post',
    'post_content' => 'Lorem ipsum dolor sit amet...',
    'post_status' => 'publish',
    'post_date' => date('Y-m-d H:i:s'),
    'post_author' => $user_ID,
    'post_type' => 'post',
    'post_category' => array(0)
);
$post_id = wp_insert_post($new_post);

How to add a featured image to post and trigger it for testing ?

What do you mean by trigger it for testing? – Sunyatasattva Apr 5 at 17:33

The post thumbnail is just saved as post meta with the key: _thumbnail_id. So after you insert the post and get the post id, you can set the post meta for that post. The $thumbnail_id is just the ID of the image you'd like to set as the thumbnail, up to you since I can't tell from your question what this should be. 

global $user_ID;
$new_post = array(
    'post_title' => 'My New Post',
    'post_content' => 'Lorem ipsum dolor sit amet...',
    'post_status' => 'publish',
    'post_date' => date('Y-m-d H:i:s'),
    'post_author' => $user_ID,
    'post_type' => 'post',
    'post_category' => array(0)
);
$post_id = wp_insert_post($new_post);

if( ! is_wp_error( $post_id ) )
       update_post_meta( $post_id, '_thumbnail_id', $thumbnail_id );

How can I test this code? If making it a function, then where should I call it? – 10wtaylor Apr 7 at 16:25
I don't know. My point was to just let you know that you could update the post meta after however you are inserting the post. – helgatheviking Apr 7 at 18:47
Post thumbnail function will automatically find any meta data having image! – 10wtaylor Apr 9 at 9:01
That's not what you asked. You asked how to programmatically set a post thumbnail when inserting a post. You do that by setting the _thumbnail_id meta key for that post. If that's not what you meant, then please revise your question for clarity. – helgatheviking Apr 9 at 9:23
Then what's the use of update_post_meta function, if post thumbnail function couldn't retrieve image from it! – 10wtaylor Apr 9 at 11:09

 $wp_filetype = wp_check_filetype(basename($filename), null );
  $wp_upload_dir = wp_upload_dir();
  $attachment = array(
     'guid' => $wp_upload_dir['url'] . '/' . basename( $filename ), 
     'post_mime_type' => $wp_filetype['type'],
     'post_title' => preg_replace('/\.[^.]+$/', '', basename($filename)),
