Testing the node form buttons (SimpleTest)

This code goes on for 89 lines, to test the node form buttons.

<?php
/**
 * Tests that the right buttons are displayed for saving nodes.
 */
function testNodeFormButtons() {

  // Login as administrative user.
  $this->drupalLogin($this->admin_user);

  // Verify the buttons on a node add form.
  $this->drupalGet('node/add/article');
  $this->assertButtons(array(t('Save and publish'), t('Save as unpublished')));

  // Save the node and assert it's published after clicking
  // 'Save and publish'.
  $edit = array('title' => $this->randomString());
  $this->drupalPostForm('node/add/article', $edit, t('Save and publish'));

  // Get the node.
  $node_1 = node_load(1);
  $this->assertTrue($node_1->isPublished(), 'Node is published');

  // Verify the buttons on a node edit form.
  $this->drupalGet('node/' . $node_1->id() . '/edit');
  $this->assertButtons(array(t('Save and keep published'), t('Save and unpublish')));

  // Save the node and verify it's still published after clicking
  // 'Save and keep published'.
  $this->drupalPostForm(NULL, $edit, t('Save and keep published'));
  $node = node_load(1, TRUE);
  $this->assertTrue($node_1->isPublished(), 'Node is published');

Testing the node form buttons (Behat)

A start at replacing the previous (not complete, but close).

Given I am logged in as a user with the "administer nodes, bypass node access" permissions
When I visit "node/add/article"
And fill in "Title" with "A sample node title"
And press "Save and publish"
Then I should see the heading "A sample node title"
