Here is a test for the blog module.
I found the following issues:
1) In checking the breadcrumbs, I used
assertText and noticed that html entities are not converted to plain text.
For example, the apostrophe ([user name]'s blog) needs to be asserted as the html entity
Is this intended or do we want to have these characters converted?
2) The statement
$this->drupalGet('admin/help/blog'); does not take you to the blog specific help, but only to the help contents page.
