Stumped newbie...

I am a pretty seasoned web developer but am new to Drupal module development. I have read a ton of stuff on designing forms, my forms display fine but the validate / submit never seems to happen and I THINK I have my module coded correctly. I have reduced to a super simple module that duplicates my issue and I know I am just missing something super simple but I would really appreciate somebody pointing me in the right direction - I am sure somebody with more experience can tell me in two seconds what I am doing wrong. My module appears as follows

<?php
/* $Id$ */

function test_menu() {
  $items = array();

  $items[] = array(
    'path' => 'test',
    'title' => t('Test Module'),
    'callback' => 'test_page',
    'access' => user_access('access test content'),
    'type' => MENU_CALLBACK
  );

  return $items;
}

function test_perm() {
  return array('access test content');
} // function train_perm()

function test_page() { 
  global $testLog;
  $testLog = "<br>---log---<br>";

  $output = '';
  $output = drupal_get_form('test_form');
  $output .= $testLog;
  return $output;
}

function test_form() { 
  global $testLog;
  $testLog .= "Building form<br>";
  $form = array();
  $form['formvalue'] = array(
    '#type' => 'textfield',
    '#title' => t('Text field'),
    '#default_value' => "");
  $form['submit'] = array(
    '#type' => 'submit',
    '#value' => t('Submit'));

  return $form;
}  

function test_form_validate($form_id, $form_values) {
  global $testLog;
  $testLog .= "Validating form<br>";
}

function test_form_submit($form_id, $form_values) {
  global $testLog;
  $testLog .= "Submitting form<br>";
}

So the form displays fine and I fill in a value and hit submit. I expect the "log" messages below will show that it is validating the form and then submitting the form but when it comes back the textfield is once again blank and it never called validate or submit. What am I doing wrong? I keep reading and re-reading the form stuff and it SEEMS I have everything in place. I am so confused.
