A better link to the SQL Cop tSQLt tests would be:
http://dl.dropbox.com/u/58229865/SQLCop%20Tests.zip
(links directly to a zip file containing all the tSQLt SQL Cop tests)
Or
http://documentation.red-gate.com/display/SQT1/SQL+Cop+static+analysis+tests
(contains links to web pages describing each of the SQL Cop tests)
