How can I change the value of a field in node / [id] / edit? I should change the value of a field before it is rendered. I tried with [NAME_MODULE]_node_view but it is not invoked when I edit the node.

Thank you so much.
I alter my forms with the following: 

function mymodule_form_test_edit_form_alter(&amp;$form, FormStateInterface $form_state, $form_id) {
  // code here...
}
